BHA Liquid Exfoliant 2%
The category gold standard. 2% salicylic acid, fragrance-free, pH-correct. The product that built Paula's Choice. Use 3× weekly maximum.
Chemical and physical exfoliants tested for surface clarity, texture refinement, and irritation profile. AHAs, BHAs, PHAs and enzyme picks across every budget.
Most people exfoliate too aggressively or with the wrong acid for their skin. The picks below are the right molecule for the job, not the loudest marketing.

AHA at the price of a coffee. Strong tone-evening over 6 weeks. Patch test — 7% glycolic is aggressive for first-timers.
Iconic Australian glycolic-acid treatment. 5% glycolic + licorice. Layered consistently, beats most $200 brightening serums.
Larger molecule = gentler than glycolic = safer on Fitzpatrick IV+ skin. The pick if you've reacted to AHAs elsewhere.
Gentle daily lactic acid. Hydrating profile rather than stripping. The right starter exfoliant for clients new to acids.
Two-step pad system. Premium positioning, real results. The pick for events where you want resurfacing the night before. Don't use weekly.
Two to three times weekly, no more. Daily exfoliation strips the barrier and triggers compensatory oil production. Most acne client recoveries we've watched start with cutting exfoliation in half.
AHA for tone and surface texture. BHA for congestion and oil. PHA for sensitive skin. Most routines benefit from one of each, not all three.

Generally no. Both increase cell turnover; together they often trigger barrier breakdown. Alternate nights at minimum.
