Reasoning: why this verdict

Glycolic acid (AHA) exfoliates the surface and salicylic acid (BHA) works inside pores, so they are often combined at balanced strengths in peels and toners. A randomized trial used AHA and BHA peels for post-acne pigmentation. Layering two separate leave-on acids daily, though, is a common route to over-exfoliation.1234

Who should be careful: Sensitive skin, rosacea and eczema-prone skin should usually stick to one exfoliant.

How to use Glycolic Acid and Salicylic Acid together

  1. Choose one product that contains both, or alternate days.
  2. Start 2-3 times a week.
  3. Wear sunscreen every day; AHAs increase UV sensitivity.
