BHA Liquid Exfoliant 2%
Reviewed by SerumTruth Editorial · Updated July 2026
A well-dosed BHA with a delivery twist that earns its slight premium over the bargain liquids, aimed at the look of clearer pores with less sting. A sensible pick if a straight salicylic acid runs your skin dry.
- Evidence21 / 30
Strength of the research behind the key actives
- Salicylic Acid: moderate evidence
- Score is the average of the key actives’ evidence grades.
- Potency25 / 25
Dosed at studied levels, not fairy-dusted
- Salicylic Acid (2%): dosed at a clinical, high-end level for its category
- Potency tracks how strongly the actives are dosed, led by the strongest, not how many there are.
- Delivery & stability18 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: encapsulated (protects and time-releases the active)
- Packaging: opaque tube
- No fragile actives here, so packaging barely moves the score.
- Formulation6 / 10
Disclosure, active breadth, and ingredient generation
- 1 of 1 actives disclose a concentration
- 1 key active (breadth credit caps at 3)
- No current-generation or synergy bonus
- Value14 / 15
What a month of use costs vs. the category
- About $8 per month to use
- $19 for 120 ml, used about once a day (about 1.75 ml each time), so a bottle lasts about 2.3 months
- Frequency is set by Salicylic Acid, which is used no more than 7x a week, so a bottle stretches further
- Band: $6/month or less earns full marks, $60/month or more hits the floor.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Salicylic Acid | 2% | Clinical |
2% encapsulated salicylic acid, disclosed, with fruit-derived acids in an alcohol-free, oil-free base, in an opaque plastic bottle. The encapsulation meters the acid out for a steadier, gentler release, which is the real point of difference from a plain 2% BHA.
How it’s delivered
Air- and light-sensitive actives (vitamin C, copper peptides) lose potency fast in the wrong packaging, so delivery and the bottle are scored, not just what’s on the label.
