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

Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Photosensitizing โ mandatory spf use. start at low frequency.

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.
