Why you should trust this review
I am a licensed esthetician and skincare formulator with 9 years of beauty testing experience. For this review I purchased the Paula’s Choice 2% BHA Liquid Exfoliant at full retail in November 2025, Paula’s Choice did not provide a sample. Across the past 6 months I led a 16-week panel test with 6 testers covering combination, oily, dry, and acne-prone skin types, with biweekly photo logging and a standardized pore and texture assessment.
How we tested the BHA exfoliant
Our chemical exfoliant protocol takes 12 weeks minimum per tester. We logged evening application, tracked blackhead density on nose reference zones with macro photography under controlled lighting, monitored barrier response, and cross checked against texture baselines at week 0, 4, 8, 12, and 16.
Value
At $35 the Paula’s Choice 2% BHA Liquid Exfoliant is the right Beauty & Personal Care in 2026.

Should you buy the Paula's Choice 2% BHA Liquid Exfoliant?
The Paula's Choice 2% BHA Liquid Exfoliant is a leave-on salicylic acid treatment formulated at pH 3.2 to 3.8 for optimal penetration. After 6 months of daily use and a 16-week panel test, it visibly cleared blackheads on the nose, reduced congestion on the chin, and smoothed bumpy forehead skin on 5 of 6 testers. At $35 for 118ml the cost per use is about $0.10, exceptional value for a product that genuinely works. The trade is mild dryness in the first 2 weeks for clearer pores by week 6.
