5 Best Chemical Exfoliants — AHA, BHA & PHA (2026)

Paula's Choice 2% BHA Liquid Exfoliant is nothing short of legendary — with over 80,000 five-star reviews and a devoted cult following spanning decades, it's the gold standard of chemical exfoliation. The formula uses 2% salicylic acid (BHA) at an optimal pH of 3.2–3.8, allowing it to penetrate deep into pores to dissolve the mixture of oil and dead skin cells that cause blackheads, whiteheads, and enlarged pores.

What makes this formula truly exceptional is what's in it beyond the BHA: green tea extract soothes inflammation while the lightweight liquid texture absorbs instantly without oiliness. It's fragrance-free, non-irritating (when used correctly), and visibly transforms skin texture within weeks. Unlike many acid treatments that sit heavy on the surface, this watery toner-like liquid sinks in and works while you sleep. For anyone with clogged pores, texture issues, or mild acne, this is the one product that will change your skin forever.

Drunk Elephant's T.L.C. Framboos is a 12% AHA/BHA blend that delivers professional-grade resurfacing from the comfort of your bathroom. The formula combines glycolic, lactic, tartaric, and citric acids (AHAs) with 1% salicylic acid (BHA) for comprehensive exfoliation at every level of the epidermis. Raspberry fruit extract and horse chestnut add antioxidant protection and soothing properties to offset the acid intensity.

At $90, this is an investment — but the results justify the price. Users report visible smoothing of fine lines, dramatic pore refinement, and a glass-like complexion within two weeks. The gel-serum texture absorbs quickly and layers well under moisturizer. Drunk Elephant's commitment to a "suspicious six"-free formula (no silicones, fragrances, drying alcohols, SLS, essential oils, or chemical screens) makes this suitable even for sensitive skin when used 2-3 nights per week. If you want the best single-product resurfacing treatment that delivers on every promise, this is it. For more luxury picks, see our anti-aging serum guide.

Sunday Riley Good Genes is the fastest-acting exfoliant in this guide — and arguably in all of skincare. The hero ingredient is high-potency purified lactic acid (an AHA) at a concentration that delivers an immediate post-application glow. Unlike glycolic acid (which is smaller and penetrates faster, sometimes causing irritation), lactic acid is a larger molecule that exfoliates more gently while also hydrating — making Good Genes one of the rare acid treatments that improves moisture levels rather than depleting them.

The formula also includes prickly pear extract (rich in amino acids for soothing), lemongrass, and licorice root for brightening. The result is skin that looks immediately smoother, plumper, and more radiant — hence the "red carpet" reputation. Use it as a 15-minute flash mask or leave it on overnight (the brand's recommended method). At $85, it's a luxury purchase, but the combination of instant gratification + long-term improvement makes it a uniquely satisfying product. A perfect companion to a good vitamin C serum for maximum glow.

COSRX PHA Moisture Renewal Power Cream is the gentle, barrier-friendly exfoliant that sensitive skin types have been waiting for. PHA (polyhydroxy acid) — specifically gluconolactone in this formula — has a larger molecular structure than AHA or BHA, meaning it penetrates the skin more slowly and causes far less irritation. It still exfoliates effectively (removing dead cells, smoothing texture) but does so without the redness, stinging, or peeling that can accompany glycolic or salicylic acid.

What makes this cream special is the holistic formulation: 50% coconut fruit extract and 2% niacinamide provide deep moisture and barrier support while the PHA gently resurfaces. This is the rare exfoliant you can use every night — even on compromised, reactive, or rosacea-prone skin. At $22, COSRX once again proves that K-beauty delivers unmatched innovation and value. If you've been burned (literally) by harsh exfoliants, start here.

Youth To The People's Kombucha + 11% AHA Toner takes a food-grade, superfood approach to exfoliation. The dual-acid formula combines lactic acid and glycolic acid at 11% total concentration, but the real innovation is the inclusion of fermented kombucha and white tea — both rich in probiotics and antioxidants that counterbalance the exfoliating acids, keeping the skin balanced rather than stripped.

This is the ideal exfoliant for those who find traditional acid toners too harsh but still want visible refinement. The kombucha delivers postbiotic benefits that support a healthy microbiome while the 11% AHA blend smooths texture and fades hyperpigmentation. The lightweight toner texture is easy to layer — apply after cleansing and before serums. Use it 2-4 times per week as a treatment step.
