Beta Hydroxy Acid vs. Glycolic Acid: Which Exfoliant Should You Choose?
With so many exfoliating acids on the market, it’s easy to get lost in the alphabet soup of AHAs and BHAs. Two of the most popular—beta hydroxy acid (BHA, usually salicylic acid) and glycolic acid (an alpha hydroxy acid, or AHA)—offer unique benefits for different skin types and concerns. Here’s how to choose the best exfoliant for your routine, based on science and dermatologists’ advice.
Glycolic acid (AHA) and salicylic acid (BHA) deliver different benefits—choose based on your skin’s needs.

What’s the Difference? BHA vs. Glycolic Acid (AHA)
- Glycolic acid (AHA): Water-soluble, works on the skin’s surface to dissolve the “glue” holding dead skin cells together. Best for smoothing texture, fading pigmentation, and boosting radiance. Also stimulates collagen for anti-aging benefits (CeraVe, Epicuren).
- Beta hydroxy acid (BHA, usually salicylic acid): Oil-soluble, penetrates deep into pores to dissolve oil and unclog blockages. Best for oily, acne-prone skin, enlarged pores, and blackheads. Has anti-inflammatory and antibacterial properties (CeraVe, NIVEA, Healthline).
How Do They Work?
- Glycolic acid: Gently exfoliates the surface, improving skin tone, fading dark spots, and reducing fine lines. Its small molecule size allows for deep penetration and effective resurfacing, but it can cause irritation if overused (La Roche-Posay, Plum Goodness).
- BHA (salicylic acid): Penetrates pores to dissolve oil, regulate sebum, and fight acne-causing bacteria. Also calms redness and inflammation, making it ideal for acne and sensitive skin (Skincare Company, Kiehl's).
Which Exfoliant Is Best for Your Skin Type?
| Skin Concern | Best Choice | Why |
|---|---|---|
| Oily, acne-prone, clogged pores | BHA (Salicylic Acid) | Penetrates and clears pores, reduces oil, calms inflammation (CeraVe, Healthline) |
| Dry, dull, rough texture, pigmentation | Glycolic Acid (AHA) | Boosts radiance, fades dark spots, smooths fine lines, hydrates (La Roche-Posay, Healthline) |
| Combination skin or multiple concerns | Both (with caution) | Alternate or use combo products for acne and pigmentation, but avoid over-exfoliation (Cosmopolitan, NIVEA) |
Key Benefits & Drawbacks
-
BHA (Salicylic Acid):
- Deep cleans pores, controls oil, reduces breakouts
- Anti-inflammatory, suitable for sensitive/acne-prone skin
- Can be drying if overused or in high concentrations
-
Glycolic Acid:
- Surface exfoliation for glow, texture, and fine lines
- Boosts collagen, hydrates, fades pigmentation
- May cause irritation or sun sensitivity if overused
What Does the Science Say?
Both glycolic acid and salicylic acid are proven to improve acne, pigmentation, and texture (IJCED, PMC). Studies show:
- Salicylic acid is more effective for active acne and oily skin, with fewer side effects (IJCED).
- Glycolic acid is superior for fading pigmentation and improving skin texture and radiance (PMC).
- Both are safe and effective when used as directed—start slow and always use sunscreen (CeraVe, Healthline).
Can You Use Both?
Yes, but introduce them gradually and avoid layering both at full strength to prevent irritation (Cosmopolitan). Many people alternate days or use combination products designed for dual-action exfoliation. Always patch test and listen to your skin.
