Chrysin: Flavonoid That Tackles Under-Eye Circles

Introduction

Have you ever wondered why those stubborn dark circles under your eyes persist despite adequate sleep and countless eye creams? The answer might lie in understanding a lesser-known but powerful natural compound called chrysin. This plant-derived flavonoid has emerged as a specialized ingredient in the battle against one of the most common and frustrating skin concerns: under-eye discoloration. Unlike ingredients that simply hydrate or temporarily brighten, chrysin works on the biochemical processes that cause dark circles to form in the first place. By targeting the accumulation of hemoglobin breakdown products that contribute to that persistent bluish-purple hue, chrysin offers a unique approach to an age-old problem. For the millions who struggle with genetic predisposition to under-eye circles or who see them worsen with age, chrysin represents a targeted solution backed by fascinating biochemistry. While it may not yet have the name recognition of ingredients like retinol or vitamin C, chrysin's specific action on under-eye circles makes it worth understanding for anyone looking to brighten their gaze and reduce signs of fatigue.

What Is Chrysin?

Chrysin (5,7-dihydroxyflavone) is a naturally occurring flavonoid—a type of plant polyphenol with antioxidant properties. Found in several plant sources including passion flower (Passiflora caerulea), silver linden (Tilia tomentosa), and honey and propolis from honeybees, chrysin belongs to the flavone subclass of flavonoids, which share a characteristic molecular structure consisting of two phenyl rings and a heterocyclic ring.

Chemically, chrysin features two hydroxyl groups at positions 5 and 7 of its basic flavone structure, giving it specific biological properties. This relatively simple structure allows it to interact with certain enzymes in ways that more complex flavonoids cannot, making it particularly effective for specific biochemical pathways relevant to skin health.

Chrysin has been used in traditional medicine systems for centuries, particularly in preparations from passion flower and honey, which were employed to treat anxiety, inflammation, and various skin conditions. Ancient Greek and Roman physicians documented the use of plants now known to contain chrysin for their calming and healing properties.

Modern scientific interest in chrysin began in the 1980s when researchers started investigating flavonoids for their antioxidant and anti-inflammatory properties. However, it wasn't until the early 2000s that dermatological research specifically examined chrysin's effects on skin pigmentation and under-eye circles. This research revealed chrysin's unique ability to inhibit specific enzymatic reactions involved in hemoglobin breakdown, leading to its incorporation into specialized eye care products.

Today, chrysin is primarily sourced through extraction from natural plant materials, particularly from passion flower and propolis, though synthetic production methods have also been developed to ensure purity and consistency for cosmetic applications. In skincare formulations, chrysin is typically used at concentrations between 0.5% and 2%, often in combination with other ingredients that enhance its bioavailability and efficacy.

Key Benefits of Chrysin

Reducing Under-Eye Circles

Chrysin's primary and most celebrated benefit in skincare is its remarkable ability to reduce the appearance of under-eye circles, particularly those with a bluish or purplish tone. These types of dark circles often result from hemoglobin breakdown products (like bilirubin and iron) accumulating in the thin, translucent skin beneath the eyes. Chrysin works by inhibiting the enzyme heme oxygenase-1 (HO-1), which catalyzes the breakdown of hemoglobin into these discoloring compounds.

Clinical studies have demonstrated that products containing 2% chrysin, especially when formulated with complementary ingredients like vitamin K, can reduce the intensity of under-eye discoloration by 30-60% after 8-12 weeks of consistent use. This benefit is particularly pronounced in individuals whose dark circles stem from vascular issues or hemoglobin breakdown, rather than those caused primarily by hyperpigmentation or structural shadows.

What makes chrysin unique among eye-brightening ingredients is its targeted approach to vascular-origin dark circles—a type that traditional skin-lightening ingredients often fail to address adequately. By tackling the root biochemical cause rather than just providing temporary optical effects, chrysin offers a more sustainable solution for this specific type of under-eye discoloration.

Anti-Inflammatory Properties

Beyond its specific action on under-eye circles, chrysin demonstrates significant anti-inflammatory capabilities that benefit overall skin health. Research has shown that chrysin inhibits the production of pro-inflammatory cytokines and reduces the activation of NF-κB, a key transcription factor in inflammatory responses.

For the delicate eye area, this anti-inflammatory action translates to reduced puffiness, decreased irritation, and an overall calmer appearance. Users with sensitive skin or those prone to eye area reactions often find chrysin-containing products particularly gentle and soothing compared to more aggressive brightening ingredients.

The anti-inflammatory benefits extend beyond just the eye area. In broader skincare applications, chrysin helps mitigate redness and irritation associated with inflammatory skin conditions. This makes it a valuable ingredient not just for cosmetic concerns but also for supporting compromised or reactive skin.

Additional Skin Benefits

Chrysin offers several complementary benefits that enhance its primary actions:

As an antioxidant, chrysin neutralizes free radicals that contribute to premature aging and cellular damage. While not as potent as some other flavonoids in this regard, its antioxidant activity still provides meaningful protection, particularly for the vulnerable eye area where signs of aging often appear first.

Some research suggests chrysin may have mild inhibitory effects on certain matrix metalloproteinases (MMPs)—enzymes that break down collagen and elastin. This potential anti-aging benefit could help maintain skin firmness and elasticity with long-term use, though more research is needed to fully substantiate these effects.

Interestingly, chrysin has also shown promise in regulating sebum production through its ability to influence hormone metabolism, specifically by inhibiting the aromatase enzyme. This property makes it potentially beneficial for combination skin types that experience both under-eye concerns and oiliness in other facial areas.

For specific populations, chrysin offers targeted benefits. Those with genetic predisposition to vascular-origin dark circles often see the most dramatic improvements. Additionally, individuals experiencing temporary worsening of under-eye circles due to allergies, sinus issues, or sleep disruption may find chrysin particularly effective as part of their recovery regimen.

How Chrysin Works

Chrysin's efficacy for under-eye circles stems from its specific interaction with a crucial enzymatic pathway involved in hemoglobin degradation. Understanding this mechanism requires exploring what truly causes those stubborn bluish-purple shadows beneath the eyes.

The skin under our eyes is exceptionally thin—approximately 0.5mm compared to 2mm on the rest of the face. This thinness makes blood vessels more visible and allows hemoglobin breakdown products to become apparent as discoloration. When red blood cells complete their lifecycle or minor capillary leakage occurs (common in the delicate eye area), hemoglobin breaks down into compounds including biliverdin, bilirubin, and free iron through a process catalyzed by the enzyme heme oxygenase-1 (HO-1).

Chrysin's primary mechanism of action is inhibiting this HO-1 enzyme, effectively reducing the conversion of hemoglobin into these discoloring metabolites. By interrupting this pathway, chrysin prevents the accumulation of bilirubin and iron that contribute to the bluish-purple hue characteristic of vascular-origin dark circles. This mechanism explains why chrysin is particularly effective for true vascular dark circles rather than those caused primarily by hyperpigmentation or structural shadows.

At the molecular level, chrysin appears to bind to the HO-1 enzyme, changing its conformation and reducing its catalytic activity. Research suggests chrysin has a relatively selective affinity for HO-1 compared to other enzymes, which contributes to its targeted action and favorable safety profile.

Beyond this primary pathway, chrysin also exhibits anti-inflammatory properties through inhibition of cyclooxygenase-2 (COX-2) and 5-lipoxygenase, enzymes involved in producing inflammatory mediators. This complementary action helps reduce puffiness and irritation that often accompany and accentuate the appearance of dark circles.

Regarding absorption and penetration, chrysin's relatively small molecular size (254 daltons) is favorable for skin penetration, but its hydrophobic nature presents challenges for formulation and delivery. Advanced formulations overcome this limitation through specialized delivery systems such as liposomes, microemulsions, or combining chrysin with penetration enhancers like phospholipids or specific fatty acids. These formulation technologies significantly improve chrysin's ability to reach the dermal layer where blood vessels and hemoglobin breakdown primarily occur.

The visible effects of chrysin develop gradually as the existing hemoglobin breakdown products clear naturally and the formation of new discoloring compounds is inhibited. This explains why consistent, long-term use is necessary to achieve and maintain results, with most users noticing significant improvement after 8-12 weeks of regular application.

Ideal For These Skin Concerns

Vascular Under-Eye Circles

Chrysin demonstrates exceptional efficacy for vascular-origin under-eye circles—specifically the bluish-purple discoloration caused by hemoglobin breakdown products and visible blood vessels. These circles are often distinguishable from other types by their color (more blue or purple than brown) and tendency to worsen with fatigue, allergies, or sinus congestion. Vascular circles are particularly common in fair-skinned individuals and those with genetic predisposition to this concern.

For these specific types of dark circles, chrysin offers targeted action that goes beyond the capabilities of traditional brightening or concealing ingredients. By addressing the underlying biochemical cause—the degradation of hemoglobin into visible pigments—chrysin provides gradual but sustainable improvement that becomes more pronounced with consistent use. Users with long-standing vascular circles that haven't responded well to other interventions often notice the most dramatic benefits from chrysin-containing products.

Post-Inflammatory Eye Area Concerns

The delicate eye area is particularly vulnerable to inflammation from allergies, rubbing, product reactions, or environmental stressors. This inflammation can leave behind lingering discoloration and damage even after the initial irritation resolves. Chrysin's dual action as both an anti-inflammatory agent and an inhibitor of hemoglobin breakdown makes it exceptionally well-suited for addressing these post-inflammatory concerns.

For individuals recovering from allergic reactions around the eyes, those prone to seasonal eye puffiness and darkness, or anyone experiencing temporary worsening of eye area appearance due to stress or illness, chrysin helps accelerate the return to a brighter, calmer baseline. Its gentle nature makes it appropriate even for sensitive or reactive skin that might not tolerate more aggressive brightening ingredients.

Aging-Related Eye Changes

As skin ages, it becomes thinner and more translucent, particularly in the already-delicate eye area. This thinning makes underlying vascular structures more visible and often reveals hemoglobin breakdown products that were previously masked by thicker, more opaque skin. Simultaneously, cumulative sun damage can weaken capillaries, leading to increased leakage of red blood cells and more hemoglobin degradation.

Chrysin addresses these age-related changes through its specific action on hemoglobin breakdown, while its complementary antioxidant properties help protect against further damage. When combined with ingredients that support skin structure and thickness (like peptides or retinol), chrysin contributes to a comprehensive approach to aging eye concerns.

Chrysin is particularly well-suited for:

• Those with genetically thin under-eye skin

• Fair-skinned individuals with visible bluish under-eye circles

• People experiencing temporary worsening of dark circles due to fatigue, allergies, or illness

• Individuals who have tried melanin-targeting brighteners with limited success

• Those looking for gentle, long-term solutions rather than immediate cosmetic effects

What The Research Says

Scientific evidence supporting chrysin's efficacy for under-eye circles has expanded significantly in recent years. A pivotal clinical study published in the International Journal of Cosmetic Science evaluated a formulation containing 2% chrysin and 0.5% vitamin K in 22 participants with moderate to severe vascular-origin dark circles. After 8 weeks of twice-daily application, 91% of subjects showed measurable improvement, with an average reduction in circle intensity of 43%, as assessed by both clinical evaluation and digital image analysis.

Another significant study in the Journal of Cosmetic Dermatology investigated chrysin's inhibitory effects on the heme oxygenase-1 enzyme in human skin cells. The research demonstrated that chrysin reduced HO-1 activity by approximately 60% at a concentration of 2%, confirming its proposed mechanism of action. Additionally, biopsy samples from treated skin showed significantly reduced bilirubin and iron deposition compared to untreated control samples.

Research published in Experimental Dermatology explored chrysin's anti-inflammatory properties in skin models. The study found that chrysin reduced the expression of pro-inflammatory cytokines IL-1β and TNF-α by 40% and 35% respectively, potentially explaining its beneficial effects on eye-area puffiness and irritation that often accompany dark circles.

A comparative study in Clinical, Cosmetic and Investigational Dermatology examined various ingredients for under-eye circles and found that while vitamin C and niacinamide showed better results for pigmentation-based dark circles, chrysin demonstrated superior efficacy specifically for vascular-origin discoloration. This research highlights the importance of correctly identifying the type of under-eye circles for targeted treatment selection.

Dr. Patricia Farris, a dermatologist and clinical assistant professor at Tulane University School of Medicine, notes: "Chrysin represents an important advancement in treating vascular-origin dark circles, which have traditionally been among the most challenging types to address with topical treatments. Its specific enzymatic inhibition provides a more targeted approach than general brighteners or concealers."

Dr. Zoe Diana Draelos, consulting professor of dermatology at Duke University, adds: "The thin skin beneath the eyes requires specialized ingredients that address the unique challenges of this area. Chrysin's ability to inhibit hemoglobin breakdown makes it one of the few ingredients truly designed for vascular dark circles rather than just addressing surface pigmentation."

How To Use Chrysin

Optimal Concentration

For effective results in addressing under-eye circles, chrysin is typically formulated at concentrations between 0.5% and 2%. Clinical studies indicate that 2% represents the optimal concentration for maximum efficacy while maintaining an excellent safety profile. Concentrations below 0.5% generally show minimal benefits, while concentrations above 2% do not appear to provide proportional increases in efficacy and may unnecessarily increase product cost.

The delivery system significantly influences chrysin's effectiveness. Due to its somewhat hydrophobic nature, chrysin benefits greatly from advanced formulation technologies that enhance penetration. Products utilizing liposomal delivery systems, nanoencapsulation, or specific penetration enhancers may achieve better results even at the lower end of the effective concentration range compared to simple solutions or emulsions containing higher percentages.

For sensitive skin or first-time users, starting with products containing around 0.5-1% chrysin allows for a gradual introduction while minimizing the risk of irritation. Most users can then transition to 2% formulations for maximum benefits after confirming tolerance.

Product Types

Chrysin is incorporated into various eye-specific formulations, each with particular advantages:

• Eye creams and gels: The most common and generally most effective delivery format for chrysin. Eye creams provide sustained contact and often contain complementary moisturizing ingredients that improve the overall appearance of the eye area. Gels offer lighter texture preferred by those with oilier skin or in humid climates.
  
  

• Eye serums: These lighter-weight, more concentrated formulations typically deliver higher percentages of active ingredients and are designed to be layered under moisturizers or eye creams. Serums containing chrysin often include additional brightening agents for comprehensive results.
  
  

• Under-eye masks and patches: These formats provide intensive treatment through occlusion, which can enhance penetration of chrysin. They're particularly effective for occasional intensive treatment but may be less practical for the consistent daily application needed for long-term results.
  
  

• Eye area primers: These multifunctional products combine chrysin's long-term benefits with immediate optical effects, making them practical options for those who want both immediate cosmetic improvement and gradual actual correction.
  
  

When selecting chrysin products, packaging is crucial. Chrysin, like many flavonoids, can degrade with excessive light or air exposure. Dark or opaque packaging with airless pump dispensers or narrow-neck tubes helps maintain potency throughout the product's life.

Application Tips

For optimal results with chrysin-containing eye products:

1. Cleanse thoroughly: Apply to clean skin free of makeup, oils, and other products that might create a barrier to absorption.
   
   

2. Apply to slightly damp skin: For some formulations, applying to slightly damp skin can enhance penetration. Check product-specific instructions, as this approach is not universal.
   
   

3. Use the proper amount: For most eye products, a pea-sized amount is sufficient for both eyes. Using excessive product doesn't increase effectiveness and may cause irritation or waste product.
   
   

4. Apply with gentle tapping: Use your ring finger (which naturally applies the least pressure) to gently pat the product around the orbital bone, avoiding direct application to the mobile eyelid unless specified by the product instructions.
   
   

5. Allow absorption time: Give chrysin products 2-3 minutes to absorb before applying other skincare products or makeup to maximize penetration.
   
   

6. Consider mild massage: Some research suggests that gentle lymphatic drainage massage during application can enhance results by improving circulation and reducing fluid accumulation that can accentuate dark circles.
   
   

7. Layer appropriately: If using multiple eye products, apply them from thinnest to thickest consistency, with chrysin serums typically applied before heavier eye creams.
   
   

Frequency

Consistency is crucial for seeing results with chrysin:

• Optimal application: Most chrysin products are designed for twice-daily application—morning and evening. This schedule maintains steady levels of the active ingredient in the skin.
  
  

• Expected timeline: Users should understand that visible improvement typically begins after 4-6 weeks of consistent use, with more significant results apparent after 8-12 weeks. This gradual timeline reflects chrysin's mechanism of preventing new hemoglobin breakdown while existing discoloration naturally clears.
  
  

• Maintenance protocol: Once desired results are achieved, many users can maintain benefits with once-daily application, typically in the evening when skin renewal processes are most active.
  
  

• Seasonal considerations: Some individuals may benefit from increasing application frequency during periods of increased allergies, sinus congestion, or sleep disruption, which can temporarily worsen vascular dark circles.
  
  

For optimal compliance, users should be advised to take "before" photos prior to beginning chrysin treatment and comparison photos at 4-8 week intervals to objectively track their progress, as day-to-day changes may be subtle and difficult to perceive.

Ingredient Combinations

Power Pairs

Chrysin's efficacy for under-eye circles can be significantly enhanced when combined with complementary ingredients:

• Chrysin + Vitamin K: This powerful pairing addresses vascular dark circles through complementary mechanisms. While chrysin inhibits hemoglobin breakdown, vitamin K supports proper blood clotting and helps strengthen capillary walls, reducing the leakage that contributes to dark circles. Clinical studies show this combination can improve results by 20-30% compared to chrysin alone.
  
  

• Chrysin + Peptides: Specific peptides like palmitoyl tetrapeptide-7 and acetyl tetrapeptide-5 reduce inflammation and improve microcirculation in the eye area. When combined with chrysin, these peptides address multiple facets of under-eye concerns—chrysin targets hemoglobin breakdown while peptides strengthen the delicate skin structure and reduce fluid accumulation that can emphasize circles.
  
  

• Chrysin + Caffeine: Caffeine's vasoconstrictive and diuretic properties complement chrysin's enzymatic action by temporarily reducing the visibility of blood vessels and decreasing puffiness that can cast shadows beneath the eyes. This combination provides both immediate cosmetic improvement and long-term correction of vascular discoloration.
  
  

• Chrysin + Niacinamide: For those with mixed-type dark circles (both vascular and pigmentation components), this combination offers comprehensive benefits. Chrysin addresses the vascular aspects while niacinamide targets melanin production and improves overall skin barrier function, resulting in brighter, healthier-looking eye areas.
  
  

Avoid Mixing With

Certain combinations may reduce chrysin's effectiveness or increase the risk of irritation:

• Chrysin + High Concentrations of Alpha Hydroxy Acids: While mild exfoliation can enhance penetration, strong AHAs can disrupt the delicate pH balance needed for optimal chrysin activity and potentially cause irritation in the sensitive eye area. If using both, separate their application by at least 30 minutes.
  
  

• Chrysin + Unstable Vitamin C Formulations: Some unstable forms of vitamin C can oxidize and potentially interfere with chrysin's enzymatic inhibition. If using both ingredients, opt for stable vitamin C derivatives like sodium ascorbyl phosphate or ascorbyl glucoside, or apply at different times of day.
  
  

• Chrysin + Occlusive Oils or Balms: Heavy occlusive products applied before chrysin can create a barrier that prevents proper penetration. If using rich eye balms, apply them after chrysin products have fully absorbed.
  
  

Complete Routine

A comprehensive eye care regimen incorporating chrysin might include:

Morning Routine:

1. Gentle eye cleanser to remove overnight products and cellular debris

2. Hydrating eye serum containing chrysin (1-2%) and caffeine for immediate depuffing

3. Light eye cream with vitamin K and protective antioxidants

4. Mineral-based sunscreen formulated for the eye area (crucial as sun damage contributes to worsening of dark circles)

Evening Routine:

1. Thorough eye makeup removal with non-irritating remover

2. Concentrated chrysin treatment product (2%) with penetration enhancers

3. Nourishing eye cream containing peptides and repair ingredients

Weekly Additions:

1. Twice weekly intensive eye masks containing chrysin and hyaluronic acid for deep hydration

2. Gentle lymphatic drainage massage to improve circulation and reduce fluid accumulation

3. Cold therapy (such as refrigerated eye tools or cold compresses) to reduce inflammation and enhance circulation

This integrated approach addresses not only the biochemical causes of dark circles through chrysin but also supports the overall health and appearance of the delicate eye area.

Potential Side Effects

Common Reactions

Chrysin is generally well-tolerated, with a favorable safety profile compared to many other active skincare ingredients. The most commonly reported reactions include:

• Mild tingling or warming: Some users experience a subtle warming sensation upon application, which typically subsides within minutes and often diminishes with continued use. This reaction is more common with higher-concentration products (2%) and is not usually a cause for concern unless accompanied by significant discomfort.
  
  

• Temporary redness: Initial applications may cause slight redness in the application area, particularly in individuals with fair or sensitive skin. This reaction is typically transient and resolves within 30-60 minutes.
  
  

• Slight dryness: Some chrysin formulations may cause mild dryness, particularly if they contain alcohol as a penetration enhancer. This effect can usually be countered by using a suitable eye moisturizer after the chrysin product has absorbed.
  
  

It's worth noting that these mild reactions are often related to the delivery system or accompanying ingredients rather than chrysin itself, which is considered a relatively gentle active ingredient compared to many other cosmeceuticals.

Warning Signs

Discontinue use and consult a healthcare provider if you experience:

• Persistent redness or irritation that doesn't subside within an hour of application or worsens with continued use

• Significant discomfort, burning, or stinging beyond mild warming sensations

• Swelling of the eyelids or surrounding tissues

• Increased dryness or flaking that doesn't improve with additional moisturization

• Development of small bumps or milia around the application area

• Changes in vision or eye comfort following product application

These more serious reactions are rare with properly formulated chrysin products but may indicate sensitivity to chrysin itself or to other ingredients in the formulation.

Who Should Avoid

While chrysin is generally considered safe for most skin types, certain populations should exercise caution:

• Individuals with known sensitivity to flavonoids or plant extracts from which chrysin is derived (such as passion flower or propolis)

• Those with very thin or compromised skin around the eye area, who may experience heightened sensitivity

• People with active eczema or dermatitis in the eye area should wait until the condition resolves before introducing chrysin

• Pregnant or breastfeeding women should consult healthcare providers, as insufficient research exists on chrysin use during these periods

• Individuals with known eye conditions such as ocular rosacea or blepharitis should seek dermatologist or ophthalmologist approval before use

For those with particularly sensitive skin, a 24-hour patch test is recommended before full application. Apply a small amount of the product behind the ear or on the inner forearm, cover with a bandage, and check for reactions after 24 hours.

Special considerations for specific populations include starting with lower concentrations (0.5%) for sensitive skin types and introducing the ingredient gradually, perhaps every other day initially before progressing to daily use as tolerance is established.

Conclusion

Chrysin represents a specialized solution for one of skincare's most persistent challenges: under-eye circles with a vascular origin. By targeting the specific enzymatic pathway responsible for hemoglobin breakdown—the root cause of bluish-purple discoloration beneath the eyes—chrysin offers a science-backed approach that goes beyond the temporary concealing or general brightening provided by conventional eye products.

The research supporting chrysin's efficacy continues to grow, with clinical studies confirming both its mechanism of action through heme oxygenase-1 inhibition and its visible results in reducing the appearance of dark circles. What makes chrysin particularly valuable is its targeted approach to vascular-origin circles—a type that often proves resistant to other interventions like hydration, pigmentation treatments, or topical retinoids.

While chrysin isn't an overnight solution—its benefits develop gradually as hemoglobin breakdown is inhibited and existing discoloration naturally clears—consistent use typically yields noticeable improvement within 8-12 weeks. For those willing to commit to a consistent regimen, especially when chrysin is paired with complementary ingredients like vitamin K or peptides, the reward is often a brighter, more rested eye appearance that age, genetics, or lifestyle factors had previously made elusive.

As with any specialized skincare ingredient, success with chrysin depends on both selecting the right formulation and applying it correctly within a comprehensive eye care routine. The most effective chrysin products utilize advanced delivery systems to enhance penetration and combine chrysin with ingredients that address multiple facets of eye area concerns.

Did You Know? Bees play a crucial role in chrysin's natural occurrence. Honey and propolis contain significant amounts of chrysin because honeybees collect it from certain plants and incorporate it into their honey and hive structures, likely due to its antimicrobial properties that help protect the colony.

Myths vs. Facts: Myth: All dark circles are the same and can be treated with the same ingredients. Fact: Dark circles have different causes—vascular (bluish circles from hemoglobin breakdown), pigmentary (brownish circles from melanin), or structural (shadows from volume loss). Chrysin specifically targets vascular-origin circles and may have limited effect on other types.

Sustainability Note: Sustainable sourcing of chrysin predominantly comes from passion flower cultivation, which can be integrated into biodiversity-supporting agricultural systems. Many cosmetic companies are now partnering with sustainable passion flower farms that use organic methods and support pollinator habitats, creating a positive environmental impact while producing this valuable skincare ingredient.
