Exfoliant
Glycolic Acid (AHA)
Glycolic acid is the most studied and most potent alpha hydroxy acid (AHA), with the smallest molecular size of any AHA allowing it to penetrate the skin more deeply than lactic, mandelic, or other AHAs. This deep penetration makes it the most effective chemical exfoliant for improving skin texture, fading hyperpigmentation, and stimulating collagen production. It has been used in dermatology for decades in concentrations ranging from 5 percent daily-use products to 70 percent professional peels. The trade-off for its potency is a higher irritation risk -- glycolic acid is not appropriate for very sensitive or rosacea-prone skin without careful introduction. For those who can tolerate it, glycolic acid is one of the most transformative ingredients available without a prescription.

How Glycolic Acid Works
Glycolic acid has a molecular weight of 76 daltons -- the smallest of all AHAs -- allowing it to penetrate the stratum corneum more efficiently. It dissolves the intercellular bonds between corneocytes, promoting exfoliation. At deeper levels, it stimulates glycosaminoglycan and collagen synthesis in the dermis. The exfoliating action requires a pH of 3.0 to 4.0 for full activity. At neutral pH, glycolic acid still provides mild humectant benefits but minimal exfoliation.
Forms in Products
Free Acid Glycolic Acid
Full-strength exfoliating form. 5 to 10 percent for daily use, 20 to 70 percent for professional peels.
Buffered Glycolic Acid
Partially neutralized to higher pH for gentler daily use. Less potent but better tolerated.
Glycolic Acid + PHA Combinations
Combined with polyhydroxy acids for gentler exfoliation with hydrating benefits.
Evidence-Based Benefits
Deep Exfoliation
The most penetrating AHA, providing the most effective surface resurfacing.
Collagen Stimulation
Clinical evidence for increased dermal collagen synthesis at consistent use.
Hyperpigmentation Fading
Removes pigmented surface cells and enhances penetration of brightening actives.
Texture Transformation
Smooths rough, bumpy, and uneven skin more effectively than any other AHA.
How to Use Glycolic Acid
Start at 5 percent concentration, 2 times per week, applied to clean dry skin in the evening. Increase to every other day after 4 weeks if tolerated. Always follow with moisturizer and use SPF 30+ daily -- glycolic acid significantly increases photosensitivity.
- Start low (5 percent) and slow (2x/week)
- Apply to dry skin -- wet skin increases penetration and irritation
- MUST use daily SPF -- glycolic acid increases sun sensitivity for up to 7 days
- Do not combine with retinoids in the same application
- Professional peels should only be done by licensed practitioners

Common Myths
Myth
Glycolic acid thins the skin
Reality
Glycolic acid thins the dead outer layer (stratum corneum) while actually thickening the living epidermis and stimulating collagen in the dermis. Net effect is healthier, stronger skin.
Myth
Higher percentage is always better
Reality
5 to 10 percent daily use is effective for most people. Higher concentrations increase irritation without proportional benefit. Professional-strength peels (20 to 70 percent) should only be used by trained practitioners.
Frequently Asked Questions
Can I use glycolic acid if I have sensitive skin?
Start at the lowest concentration (5 percent) once per week. If your skin tolerates it after 4 weeks, gradually increase. If irritation persists, switch to lactic acid (gentler) or PHA (gentlest). Some sensitive skin types cannot tolerate any glycolic acid, and that is fine -- alternatives exist.
How does glycolic acid compare to retinol for anti-aging?
They work through different mechanisms and complement each other well. Glycolic acid exfoliates the surface for immediate texture improvement. Retinol normalizes cell turnover and stimulates collagen from within for deeper structural improvement. Using glycolic 2 to 3 nights and retinol on alternate nights is a powerful anti-aging strategy.
