Ingredients Details
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 โ 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 โ 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%โ5%
SOURCING & ETHICS
Vegan Status: Yes โ enzymatic synthesis from ascorbic acid and glucose
Halal Status: Yes
Source Notes: Synthetically produced vitamin c derivative.
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: 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 โ providing both formulation stability and bioactivation where needed.

Dipropylene Glycol
Common Name(s): Dipropylene glycol,glycol co-solvent,humectant formulation aid
CAS Number: N/a
DESCRIPTION
What It Does: Provides humectant, co-solvent, and fragrance fixative in cosmetic formulations, improving active ingredient dissolution and product texture while delivering mild skin conditioning.
Why It's Used: Glycol solvents are essential for dissolving actives with limited water or oil solubility โ the intermediate polarity of glycol ethers provides access to the wider solubility parameter space between pure water and oil phases.
How It Works: Hydroxyl and ether groups provide h-bonding for water miscibility; the organic chain provides compatibility with lipophilic actives. medium-chain glycols (c3โc6) provide the optimal balance of water compatibility, lipophilic active dissolution, and skin-compatible humectancy.
Typically Found In: Skin care formulations,co-solvent systems
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: 1%โ30%
SOURCING & ETHICS
Vegan Status: Yes
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
Glycol ether co-solvents enhance sc penetration of co-applied actives by increasing their thermodynamic activity in the sc lipid phase โ high thermodynamic activity (near saturation) drives diffusion by concentration gradient even when absolute concentration is low.

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.

Glycolic Acid
Common Name(s): Hydroxyacetic acid,2-hydroxyacetic acid
CAS Number: 79-14-1
DESCRIPTION
What It Does: Provides maximum aha efficacy from the smallest most penetrating alpha-hydroxy acid.
Why It's Used: The most potent aha โ glycolic acid's smallest molecular size provides the deepest penetration and highest efficacy of any alpha-hydroxy acid for exfoliation and anti-aging.
How It Works: Smallest aha (mw 76) provides deepest stratum corneum penetration. disrupts corneodesmosomes reducing cohesion. stimulates fibroblast collagen i and iii synthesis. efficacy is ph-dependent โ free acid fraction determines activity.
Typically Found In: Chemical peels,body lotions,anti-aging serums,exfoliating toners
TECHNICAL DETAILS
Primary Category: Active ingredient โ primary aha
Secondary Functions: Brightening,collagen stimulation
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ10% cosmetic; higher professional
SOURCING & ETHICS
Vegan Status: Yes โ synthetic or fermentation-derived
Halal Status: Yes
Source Notes: Fermentation-derived or synthetic. ph must be โค4.0 for aha activity.
SKIN COMPATIBILITY
Irritancy Rating: 2/5 โ low to moderate
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Photosensitizing โ mandatory spf use. start at low frequency.
Safe for Sensitive Skin: Use with caution โ spf required
SAFETY & COMPATIBILITY
Safety Profile: Eu cosmetics: max 10% leave-on, ph โฅ3.5, mandatory sun protection advisory. professional peel concentrations regulated separately.
Works Well With: Niacinamide,ceramides,hyaluronic acid,spf
Avoid Combining With: Retinol in same step; multiple exfoliants simultaneously
SCIENTIFIC NOTE
Glycolic acid's ph-dependent efficacy is critical: at ph 3.0 ~100% is in the free acid (membrane-permeable) form; at ph 3.5 ~70%; at ph 4.0 ~50%. the eu ph โฅ3.5 requirement reduces free acid proportion, lowering efficacy but also reducing irritation โ why professional peel concentrations at lower ph are far more active than equivalent cosmetic concentrations.
