Glycolic Acid
Glycolic Acid for Removing Surface Tan, Brightening Dull Skin, and Accelerating Post-Acne Mark Fading: Complete Ingredient Guide
The smallest AHA molecule, penetrating most efficiently to speed up cell turnover. Dr. Sheth’s pairs it with Gulab (Rose) to soothe the skin and provide antioxidant support during exfoliation.
Glycolic Acid works through surface exfoliation by breaking chemical bonds holding dead skin cells together, accelerates removal of melanin-rich cells causing tan and dark spots, and stimulates collagen production at higher concentrations.

What Is Glycolic Acid and Why Does It Work?
The smallest AHA molecule, penetrating most efficiently to speed up cell turnover. Dr. Sheth’s pairs it with Gulab (Rose) to soothe the skin and provide antioxidant support during exfoliation.
Glycolic Acid works through surface exfoliation: it breaks chemical bonds holding dead skin cells together, accelerates removal of melanin-rich cells causing tan and dark spots, and stimulates fibroblasts to produce more collagen at higher concentrations.
Functional Role in Skincare
| Functional Role | Category | Sub-role Mechanism |
|---|---|---|
| Primary Active | Exfoliant | Breaks chemical bonds holding dead skin cells together |
| Primary Active | Pigmentation Corrector | Accelerates removal of melanin-rich cells causing tan and dark spots |
| Supporting Active | Collagen Stimulator | Signals fibroblasts to produce more collagen at higher concentrations |
Skin Concerns Glycolic Acid Treats
| Skin Concern | Root Cause Addressed | Mechanism of Action | Studied Concentration | Research Anchor |
|---|---|---|---|---|
| Surface Tan & UV Pigmentation | Triggered by year-round intense UV exposure triggering excess melanin production at the skin surface | Accelerates removal of melanin-rich cells causing tan and dark spots | 5-30% | J Cutan Aesthet Surg, 2013 (PMID 24326003) |
| Dull Skin from Dead Cell Buildup | Triggered by outdoor heat, sweat, sunscreen, and pollution creating a layer of dead cells | Surface exfoliation | 5-30% | Dermatol Surg, 1997 |
Why Glycolic Acid Is Effective for Indian Skin and Climate
Tan removal is consistently one of the top skincare search queries in India due to high UV exposure. Glycolic acid is the most clinically validated cosmetic ingredient for removing surface-level pigmentation. Dr. Sheth's pairs it with Gulab (Rose) to provide soothing, anti-inflammatory support, preventing redness that can trigger rebound pigmentation in Indian skin.
How Glycolic Acid Works: Three Mechanisms of Action
1. Surface Exfoliation
Breaks chemical bonds holding dead skin cells together.
2. Pigmentation Correction
Accelerates removal of melanin-rich cells causing tan and dark spots.
3. Collagen Stimulation
Signals fibroblasts to produce more collagen at higher concentrations.
Clinical Evidence: Peer-Reviewed Research
| Concentration | Outcome Measured | Study Type | Source & Year | Key Finding |
|---|---|---|---|---|
| 5-30% | Improvement in PIH | Clinical Study | J Cutan Aesthet Surg, 2013 | Significant improvement in post-inflammatory hyperpigmentation in Indian skin. (PMID 24326003) |
Who Should Use Glycolic Acid: Skin Type Guide
| Primary Concern | Skin Type | Severity | Recommended Approach |
|---|---|---|---|
| Surface tan and dullness | Oily, combination, normal | Mild to moderate | Start with 5-7% 2-3 times per week in the evening |
