Best Lactic Acid 10% Serums for Sensitive Acne-Prone Skin India (2026)

The Gentle AHA Exfoliator for Sensitive Indian Skin

Lactic Acid is an alpha hydroxy acid (AHA) derived from fermented milk or sugars. Unlike smaller AHA molecules like Glycolic Acid (which dive quickly into the dermis and can trigger stinging or post-inflammatory hyperpigmentation on Fitzpatrick IV-VI skin), Lactic Acid works gradually on the uppermost stratum corneum.

Furthermore, Lactic Acid uniquely possesses intrinsic humectant properties, drawing atmospheric moisture into skin cells while dissolving the 'cellular glue' (desmosomes) holding dead, dull skin cells together.

💡 Molecular Size Comparison

Glycolic Acid molecular weight is 76 Da; Lactic Acid molecular weight is 90 Da. The larger structure of Lactic Acid limits rapid irritation while delivering smooth, glowing skin texture.

Frequently Asked Questions (FAQ)

Lactic Acid has a larger molecular weight than Glycolic Acid. It penetrates the epidermis more slowly and uniformly, causing significantly less stinging, burning, or redness.

Yes! Lactic Acid is a natural humectant that increases natural moisturizing factor (NMF) levels in the skin barrier while breaking intercellular desmosome bonds.

Start by applying 10% Lactic Acid serum 2 to 3 nights per week. Once your skin builds tolerance, you can increase to every alternate night.

Mild purging (small whiteheads rising to the surface) can occur during the first 2 weeks as dead cell layers shed, releasing trapped microcomedones.

To avoid barrier compromise, do not layer them simultaneously at night. Use Salicylic Acid face wash in the morning and Lactic Acid serum 2-3 nights per week.
