Best Exfoliants 2026: AHA vs BHA for Smooth, Glowing Skin
Exfoliation is the step that takes skin from dull to glowing — but it is also the one people most often overdo. Done right, a chemical exfoliant clears congestion, smooths texture and reveals brighter skin. Done wrong, it leaves you red, stinging and worse off than before.
The trick is choosing the right acid for your skin and using it sparingly. Here are the five best chemical exfoliants of 2026, with honest pros and cons, plus a plain-English guide to AHA versus BHA.

It is simpler than it sounds. AHAs (glycolic, lactic) are water-soluble and work on the skin's surface — best for dullness, texture, tone and dryness. BHA (salicylic acid) is oil-soluble, so it gets inside pores — best for oily, acne-prone, blackhead-prone skin. PHAs are the gentlest, great for sensitive skin.
Pick one lane to start. Oily and breakout-prone? Begin with a BHA. Dry, dull or uneven? Begin with an AHA. Sensitive? Start with lactic acid or a PHA. Use it two to three nights a week, build up slowly, and always wear sunscreen — acids make skin more sun-sensitive.
Exfoliation is a nudge, not a scrub. Less, done consistently, beats more done aggressively.
Frequently Asked Questions
What is the difference between AHA and BHA?
AHAs (like glycolic and lactic acid) are water-soluble and work on the surface for tone and texture. BHA (salicylic acid) is oil-soluble and gets into pores, making it best for oily, acne-prone skin.
What is the best chemical exfoliant?
Paula's Choice 2% BHA is the cult favourite for pores and blackheads. For glow and texture, The Ordinary Glycolic Acid 7% toner is a brilliant budget AHA.
How often should I exfoliate?
Two to three times a week for most people. Start once or twice weekly and build up. Daily exfoliation usually over-does it and damages the barrier.
Can I use AHA and BHA together?
Some products combine them safely at low strengths. But do not layer multiple strong acids yourself, and never pair them with a retinoid the same night.
The Bottom Line
The right exfoliant transforms dull skin — just use it gently. Paula's Choice 2% BHA wins for pores and acne; The Ordinary Glycolic 7% for glow; Lactic Acid 5% for sensitive skin. Two to three nights a week, build slowly, and never skip the SPF.
