Ingredients Details
Argania Spinosa Argan Kernel Oil
Common Name(s): Argania spinosa argan kernel oil oil
DESCRIPTION
What It Does: Nourishes and softens skin through its balanced fatty acid profile, while antioxidant compounds protect against oxidative skin damage.
Why It's Used: Plant oils provide physiologically compatible lipid structures that integrate into the skin barrier and deliver fat-soluble antioxidants directly to skin cells.
How It Works: Fatty acids integrate into stratum corneum lipid lamellae, reinforcing the lipid barrier. antioxidants (tocopherols, carotenoids, polyphenols) neutralize ros through electron donation or singlet oxygen quenching.
Typically Found In: Face oils,serums,moisturizers,hair treatments,body oils
TECHNICAL DETAILS
Primary Category: Plant oils
Secondary Functions: Emollient,antioxidant
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.5โ30%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Cold-pressed or solvent-extracted plant oil; no animal components.
SKIN COMPATIBILITY
Irritancy Rating: 1899-12-31 00:00:00 -0800
Comedogenicity Rating: 1900-01-01 00:00:00 -0800
Sensitivity Concerns: Low sensitization potential at recommended use concentrations.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Well-characterized cosmetic ingredient with established safety profile. generally non-irritating at typical use concentrations. suitable for leave-on and rinse-off cosmetics.
Works Well With: Vitamin e,ceramides,other plant oils,squalane
Avoid Combining With: Strong oxidizers (accelerate rancidity)
SCIENTIFIC NOTE
Vegetable oils are triglyceride matrices where the fatty acid composition determines skin compatibility, barrier function, and comedogenicity. oleic acid-rich oils (>60%) soften barrier lipids and enhance penetration; linoleic acid-rich oils reinforce ceramide-poor stratum corneum; saturated fatty acid-rich oils provide occlusion without skin penetration.

Betaine
Common Name(s): Trimethylglycine,tmg,natural betaine
CAS Number: 107-43-7
DESCRIPTION
What It Does: Provides osmoprotective humectant conditioning with anti-irritant and mild foam-boosting activity.
Why It's Used: Natural-origin multifunctional osmolyte from sugar beet providing hydration, anti-irritancy, and conditioning in virtually every cosmetic category.
How It Works: Quaternary ammonium betaine provides zwitterionic character for water binding via ionic hydration. osmoprotective function at 100โ500mm as compatible solute protecting cells from osmotic stress. reduces surfactant irritation by competing with sls for protein binding sites. mild foam enhancement.
Typically Found In: Virtually all categories โ moisturisers, shampoos, cleansers
TECHNICAL DETAILS
Primary Category: Functional ingredient โ humectant
Secondary Functions: Tewl reduction,skin plumping
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.5%โ10%
SOURCING & ETHICS
Vegan Status: Yes โ from beta vulgaris (sugar beet) molasses
Halal Status: Yes
Source Notes: Synthetic or naturally derived. excellent aqueous solubility.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating; suitable for all skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Ceramides,emollients,occlusives,glycerin,hyaluronic acid
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Betaine's anti-irritant mechanism for surfactant systems involves competitive protein protection: betaine at high concentrations preferentially interacts with skin proteins, occupying binding sites that would otherwise be occupied by surfactant molecules causing protein denaturation. this competition reduces available protein binding for irritating surfactants, explaining betaine's well-documented ability to reduce sls irritation when co-formulated.

Glycerin
Common Name(s): Glycerol,glycerine,1,2,3-propanetriol
CAS Number: 56-81-5
DESCRIPTION
What It Does: Glycerin pulls water from the environment and deeper skin layers into the outer skin layer (epidermis), boosting moisture levels and keeping skin soft, smooth, and plump.
Why It's Used: It is used in virtually every moisturizer, serum, and cleanser because it is highly effective at hydrating skin, is well-tolerated by all skin types, and enhances the texture and spreadability of formulations.
How It Works: As a humectant, glycerin forms hydrogen bonds with water molecules, trapping them in the skin. it also reinforces the skin barrier by integrating into lipid structures between skin cells.
Typically Found In: Moisturizers,serums,cleansers,toners,sheet masks,sunscreens,body lotions,shampoos,conditioners
TECHNICAL DETAILS
Primary Category: Humectant
Secondary Functions: Skin barrier support,emollient,solvent
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ30% (typical: 3โ10%)
SOURCING & ETHICS
Vegan Status: Yes โ plant-derived (coconut, soy, palm) or synthetic
Halal Status: Yes โ when plant-derived or synthetic; verify source with supplier
Source Notes: Derived from plant oils via hydrolysis or saponification; synthetic versions also available. palm-derived glycerin carries sustainability concerns.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low; non-irritating at all standard concentrations
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Extremely rare allergic reactions; generally safe for all skin types including sensitive and baby skin
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Widely recognized as safe. ewg hazard score: 1. no significant concerns for irritation, sensitization, or toxicity at typical concentrations (up to 50%).
Works Well With: Hyaluronic acid,ceramides,niacinamide,panthenol,urea,peptides,retinol,ahas/bhas
Avoid Combining With: No known incompatibilities at standard concentrations
SCIENTIFIC NOTE
Glycerin is an endogenous skin component found naturally in the stratum corneum. aquaporin-3 channels in keratinocytes facilitate glycerin transport, making it integral to natural skin hydration pathways.
