Ingredients Details
Acetyl Glucosamine
Common Name(s): Acetyl glucosamine,cosmetic active,functional ingredient
CAS Number: N/a
DESCRIPTION
What It Does: Delivers characteristic cosmetic function — skin conditioning, protection, preservation, or active biological benefit — at recommended use concentration.
Why It's Used: Selected for its functional contribution and formulation compatibility — supported by cosmetic science literature and regulatory safety assessment.
How It Works: Works through the mechanism of its molecular class — physicochemical interaction with the formulation or biological interaction with skin proteins, lipids, or receptors as documented in peer-reviewed literature.
Typically Found In: Skin care formulations
TECHNICAL DETAILS
Primary Category: Active ingredient – cosmetic active
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%–10%
SOURCING & ETHICS
Vegan Status: Conditional
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1–2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Acetyl glucosamine delivers documented functional benefit with an established safety profile within the cosmetic regulatory framework (cosing eu, cir usa).

Algae Extract
Common Name(s): Algae extract,botanical extract,phytochemical active
CAS Number: N/a
DESCRIPTION
What It Does: Provides antioxidant protection from reactive oxygen species, reduces inflammatory cytokine production in skin, and conditions skin surface through the plant's secondary metabolite complex.
Why It's Used: Chosen for its natural origin narrative, traditional use heritage, and multi-functional phytochemical profile that supports several concurrent skin care claims from one ingredient.
How It Works: Polyphenols, terpenoids, and alkaloids in the extract scavenge ros via hydrogen atom transfer, inhibit nf-kb or cox-2 inflammatory pathways, and interact with skin surface proteins for conditioning.
Typically Found In: Botanical skin care,natural products
TECHNICAL DETAILS
Primary Category: Active ingredient – antioxidant
Secondary Functions: Free radical scavenging,anti-aging
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%–10%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Plant-derived extract or synthetic.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Non-irritating; well-tolerated.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Vitamin c,vitamin e,ferulic acid,spf,other antioxidants
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Plant secondary metabolites evolved as uv photoprotectants and antimicrobial agents — mechanisms that directly translate to cosmetic antioxidant and anti-inflammatory activity in human skin.

Ascorbyl Glucoside
Common Name(s): Aa2g,2-o-alpha-d-glucopyranosyl-l-ascorbic acid
CAS Number: 129499-78-1
DESCRIPTION
What It Does: Provides stable gradual-release vitamin c activity for brightening and antioxidant protection.
Why It's Used: Most formulation-stable vitamin c derivative — ascorbyl glucoside remains stable in aqueous formulations where pure ascorbic acid oxidises within days, providing sustained vitamin c delivery over weeks of shelf life.
How It Works: Alpha-glucoside bond resists oxidation until cleaved by skin alpha-glucosidase enzymes. releases free l-ascorbic acid in viable epidermis. released ascorbic acid inhibits tyrosinase, stimulates collagen synthesis, and provides antioxidant activity. glucose group provides enhanced water solubility vs ascorbic acid.
Typically Found In: Stable vitamin c serums,brightening products,anti-aging
TECHNICAL DETAILS
Primary Category: Active ingredient – stable vitamin c glucoside
Secondary Functions: Tyrosinase inhibitor,collagen cofactor
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%–5%
SOURCING & ETHICS
Vegan Status: Yes – enzymatic synthesis from ascorbic acid and glucose
Halal Status: Yes
Source Notes: Synthetically produced vitamin c derivative.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – 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: Tocopherol,ferulic acid,niacinamide,spf
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Ascorbyl glucoside's stability advantage (18+ months in aqueous formulation vs days for ascorbic acid) arises from the glucose group's steric protection of ascorbic acid's c2 enediol that is the primary oxidation site. glucosidase cleavage in skin removes this protection in situ, releasing active ascorbic acid only where enzymatic activity exists — providing both formulation stability and bioactivation where needed.

Butylene Glycol
Common Name(s): 1,3-butanediol,bg,1,3-butylene glycol
CAS Number: 107-88-0
DESCRIPTION
What It Does: Provides humectant hydration and active ingredient solubilization with excellent skin feel.
Why It's Used: Preferred glycol humectant in premium and k-beauty formulations for superior skin feel vs propylene glycol with equivalent functionality.
How It Works: Two hydroxyl groups at 1,3-positions provide water binding and solvent activity. better tolerated than propylene glycol with minimal sensitization risk. 4-carbon backbone provides slightly greater hydrophobic character enabling dissolution of less polar actives vs pg.
Typically Found In: Toners,essences,serums,k-beauty formulas
TECHNICAL DETAILS
Primary Category: Functional ingredient – glycol 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: 1%–10%
SOURCING & ETHICS
Vegan Status: Yes – synthetic
Halal Status: Yes
Source Notes: Synthetic or naturally derived. excellent aqueous solubility.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – 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
K-beauty's preference for butylene glycol over propylene glycol is driven by two factors: bg's superior skin feel (less tacky than pg's higher viscosity) and its lower sensitization potential (1,3-bg has better spatial distribution of hydroxyl groups that reduces protein interaction vs pg's 1,2-position oh groups).
