Glycolic Acid vs. Salicylic Acid: Know the Difference
By Shumaila Saeed & Dua Fatima || Published on December 14, 2024
Glycolic acid, an AHA, exfoliates surface skin, enhancing texture and brightness, while salicylic acid, a BHA, penetrates pores to reduce acne and inflammation.
Key Differences
Glycolic acid is a water-soluble alpha hydroxy acid (AHA) derived from sugar cane, known for its ability to exfoliate the skin and reduce signs of aging. Salicylic acid, on the other hand, is a lipid-soluble beta hydroxy acid (BHA) that is effective in penetrating oily skin and unclogging pores.

Glycolic acid works by dissolving the bonds between skin cells on the surface, allowing lost cells to be washed away, salicylic acid goes deeper, breaking down the bonds inside the pores to clear out blockages, making it particularly beneficial for acne-prone skin.
