Also known as: AHA, Alpha Hydroxy Acid
The smallest AHA molecule, allowing deeper penetration. Glycolic acid exfoliates the skin surface by dissolving the bonds between dead skin cells.
Exfoliates dead skin cells, improves skin texture, reduces hyperpigmentation, stimulates collagen, brightens dull skin.
Start with low concentrations (5-8%) 2-3 times per week. Increase gradually. Use in evening routine. Always use sunscreen during the day.
Extensive evidence for improving photodamaged skin, hyperpigmentation, and acne. Higher concentrations (20-70%) used in professional chemical peels.
Can cause irritation, stinging, and sun sensitivity. Not recommended for very sensitive or rosacea-prone skin. Avoid mixing with retinoids initially.
