AHA vs BHA for Acne

Which chemical exfoliant targets your specific type of breakouts.

Both AHAs (glycolic, lactic, mandelic acid) and BHAs (salicylic acid) can help with acne, but they work differently. BHA is oil-soluble and penetrates inside pores — best for blackheads, whiteheads, and oily skin. AHAs are water-soluble and work on the skin's surface — better for post-acne marks, texture, and comedonal acne on dry/normal skin.

Choosing the Right Exfoliant for Your Acne

BHA for Active Breakouts

Salicylic acid (BHA) dissolves oil inside pores, clearing existing clogs and preventing new ones. If your acne involves blackheads, visible pores, or oily T-zone breakouts, BHA is your first choice.

AHA for Marks & Texture

Glycolic and lactic acid speed up surface cell turnover, fading post-acne marks and smoothing rough texture. If your main concern is the scars and discoloration acne leaves behind, AHAs are more effective.

Combination for Stubborn Acne

Some people benefit from both — BHA in the evening (pore clearing) and a gentle AHA 2-3 times per week (surface renewal). Alternate rather than layer to avoid over-exfoliation.
