Ingredients Details
Acetyl Glycyl Beta-alanine
Common Name(s): Acetyl glycyl beta-alanine,acetyl glycyl beta-alanine,beta-alanine modified peptide,carnosine biosynthesis stimulating anti-aging
CAS Number: N/a
DESCRIPTION
What It Does: Stimulates collagen synthesis through peptide sequence receptor activation while simultaneously providing beta-alanine for carnosine biosynthesis โ dual anti-aging mechanism from collagen upregulation and anti-glycation protection.
Why It's Used: Combining signal peptide collagen stimulation with beta-alanine carnosine precursor in one molecule provides synergistic anti-aging from two independent mechanisms โ dermal matrix upregulation (collagen synthesis) and dermal matrix protection (age prevention).
How It Works: The peptide sequence activates tgf-ฮฒ/smad โ col1a1 upregulation. beta-alanine simultaneously enters the carnosine pathway: beta-alanine + histidine โ carnosine (by carnosine synthetase) โ carbonyl quenching of methylglyoxal/4-hne preventing age crosslinks on collagen. the dual mechanism addresses both collagen quantity and quality.
Typically Found In: Premium anti-aging serums
TECHNICAL DETAILS
Primary Category: Active ingredient โ peptide
Secondary Functions: Collagen synthesis,anti-aging
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1โ5000 ppm
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Synthetically produced via solid-phase peptide synthesis (spps).
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating at recommended concentrations.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Retinoids,niacinamide,vitamin c,hyaluronic acid
Avoid Combining With: Strong acids below ph 3.5; oxidising agents
SCIENTIFIC NOTE
Beta-alanine-containing peptides provide superior carnosine pathway stimulation versus free beta-alanine โ the peptide scaffold improves sc penetration delivering beta-alanine deeper into the dermis where carnosine synthetase is concentrated in fibroblasts.

Artocarpus Lakoocha Wood Extract
Common Name(s): Artocarpus lakoocha wood extract,cosmetic active ingredient,established formulation function
CAS Number: N/a
DESCRIPTION
What It Does: Artocarpus lakoocha wood extract delivers its characteristic primary cosmetic function โ whether active skin conditioning, antioxidant protection, antimicrobial preservation, rheological control, or sensory enhancement โ contributing measurable formulation value at its recommended use concentration.
Why It's Used: Formulators select artocarpus lakoocha wood extract for its specific functional chemistry that provides the required outcome in their formulation โ skin bioactivity, stability contribution, or consumer experience โ supported by cosmetic science and regulatory safety data.
How It Works: Artocarpus lakoocha wood extract works through the fundamental chemical and biological mechanisms of its molecular class. its physicochemical properties (molecular weight, logp, pka, functional groups) determine interactions with skin proteins, lipid membranes, formulation matrices, and biological receptors โ mechanism detailed in peer-reviewed cosmetic chemistry literature.
Typically Found In: Skin care formulations,active products
TECHNICAL DETAILS
Primary Category: Active ingredient โ 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%โ10%
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 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic

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 โ 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%โ10%
SOURCING & ETHICS
Vegan Status: Yes โ synthetic
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
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).

Gluconolactone
Common Name(s): D-gluconolactone,delta-gluconolactone
CAS Number: 90-80-2
DESCRIPTION
What It Does: Provides the gentlest chemical exfoliation with simultaneous antioxidant, moisture retention, and barrier support.
Why It's Used: Preferred exfoliant for rosacea, eczema, sensitive skin, and post-procedure recovery where standard ahas cause unacceptable irritation.
How It Works: Hydrolyzes slowly on skin surface to gluconic acid providing gentle exfoliation. multiple hydroxyl groups enable water binding (humectant) and metal chelation (antioxidant).
Typically Found In: Sensitive skin exfoliants,rosacea treatments,eczema care,post-procedure recovery
TECHNICAL DETAILS
Primary Category: Active ingredient โ polyhydroxy acid (pha)
Secondary Functions: Gentle exfoliation,antioxidant,humectant
