The verdict
For texture and pigmentation, Tretinoin is the stronger option, while Lactic Acid is gentler and better suited to sensitive or beginner skin.
Using both? Use with caution Both Lactic Acid and Tretinoin speed up cell turnover. Used in the same routine they commonly cause redness, peeling and a damaged barrier, especially in India's heat and humidity. Alternate nights instead. How to layer them →
Lactic Acid in short
A gentler AHA with a larger molecule. It exfoliates while also acting as a humectant, so it suits dry and sensitive skin that cannot tolerate glycolic acid.
Tretinoin in short
The prescription-strength retinoid, and the gold standard for acne and photo-ageing, with decades of evidence. It works directly (no conversion needed), so it is stronger and more irritating than retinol or retinal.
