A chemical exfoliant lives or dies on whether it resurfaces effectively without wrecking the barrier, so we scored performance, value, and gentleness together. Our pick is Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant, with an SR Score of 91, the most awarded leave-on salicylic acid in the category and a properly pH-formulated benchmark. The Ordinary Glycolic Acid 7% Toning Solution (87) is the cheap AHA workhorse. For a budget BHA, Naturium BHA Liquid Exfoliant 2% (86) matches the leader’s active for less.

Methodology
The Beauty Score v2026 rubric weights five criteria:
- Performance (30) — measurable resurfacing of texture, pores, and tone.
- Value for money (25) — cost per ounce against results.
- Gentleness (20) — how well it resurfaces without over-stripping the barrier.
- Feel & finish (15) — texture, residue, and tolerability.
- Reputation & reviews (10) — awards and large-sample ratings.
Performance and value lead, but gentleness carries real weight because the fastest route to bad skin is over-exfoliation. Re-weight Gentleness higher and the lactic and PHA-style picks climb.
Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant
The category benchmark. Around $35 for 4 oz. A leave-on 2% salicylic acid liquid formulated at the right pH, it has won multiple 2025 editorial awards for best chemical exfoliant and is the most-recommended BHA for pores and congestion. It clears and refines without the grit of a scrub.
| Criterion | Score |
|---|---|
| Performance | 29/30 |
| Value for money | 22/25 |
| Gentleness | 18/20 |
| Feel & finish | 13/15 |
| Reputation & reviews | 10/10 |
Trade-off: not cheap, and a faint salicylate scent that some dislike.
The Ordinary Glycolic Acid 7% Toning Solution
The cheap AHA workhorse. Around $13 for 8 oz. A 7% glycolic toner that gently resurfaces and brightens, at an unbeatable cost per ounce. A staple for dull, uneven skin.
| Criterion | Score |
|---|---|
| Performance | 25/30 |
| Value for money | 25/25 |
| Gentleness | 15/20 |
| Feel & finish | 13/15 |
| Reputation & reviews | 9/10 |
Trade-off: glycolic can sting sensitive skin, and daily use is too much for many.
Naturium BHA Liquid Exfoliant 2%
The budget BHA. Around $19 for 3.4 oz. A 2% salicylic acid liquid that mirrors the Paula’s Choice active at a lower price, the obvious value alternative for oily, congested skin.
| Criterion | Score |
|---|---|
| Performance | 26/30 |
| Value for money | 23/25 |
| Gentleness | 17/20 |
| Feel & finish | 13/15 |
| Reputation & reviews | 8/10 |
Trade-off: a slightly less refined formula and smaller review base than the leader.
Paula’s Choice 6% Mandelic + 2% Lactic AHA
The gentle all-skin AHA. Around $36 for 3.7 oz. A blend of large-molecule mandelic acid and lactic acid that is one of the brand’s gentlest exfoliants, suitable across skin types including those who find glycolic harsh.
| Criterion | Score |
|---|---|
| Performance | 24/30 |
| Value for money | 18/25 |
| Gentleness | 19/20 |
| Feel & finish | 14/15 |
| Reputation & reviews | 8/10 |
Trade-off: gentler means slower visible resurfacing than a strong glycolic.
The Ordinary Lactic Acid 10% + HA
The sensitive AHA. Around $9 for 1 oz. A 10% lactic acid serum with hyaluronic acid, lactic being milder than glycolic, making it a good entry exfoliant for reactive skin.
| Criterion | Score |
|---|---|
| Performance | 22/30 |
| Value for money | 23/25 |
| Gentleness | 17/20 |
| Feel & finish | 13/15 |
| Reputation & reviews | 8/10 |
Trade-off: lower potency than the pore-clearing BHAs for congestion.
The Ordinary AHA 30% + BHA 2% Peeling Solution
The weekly deep peel. Around $10 for 1 oz. A potent 30% AHA and 2% BHA rinse-off mask for occasional deep resurfacing, dramatic but strong.
| Criterion | Score |
|---|---|
| Performance | 25/30 |
| Value for money | 22/25 |
| Gentleness | 11/20 |
| Feel & finish | 11/15 |
| Reputation & reviews | 8/10 |
Trade-off: strictly a weekly 10-minute treatment; daily use would damage the barrier.
CeraVe Skin Renewing Nightly Exfoliating Treatment
The barrier-friendly pick. Around $20 for 1.7 oz. A gentle AHA-and-ceramide nightly exfoliant designed to resurface while supporting the barrier, the conservative choice.
| Criterion | Score |
|---|---|
| Performance | 21/30 |
| Value for money | 19/25 |
| Gentleness | 18/20 |
| Feel & finish | 13/15 |
| Reputation & reviews | 8/10 |
Trade-off: mild enough that results are slow for heavily congested skin.
How to choose an exfoliant
Match the acid to your skin. Oily, congested, or blemish-prone skin wants BHA, where Paula’s Choice 2% BHA is the benchmark and Naturium is the value twin. Dry, dull, or sun-damaged skin wants an AHA, where The Ordinary’s glycolic toner is the cheap workhorse and the mandelic-lactic blend is the gentle all-rounder. Whatever you pick, start two or three times a week and back off at the first sign of stinging or tightness; over-exfoliation is the most common self-inflicted skin problem. Re-weight the rubric toward Gentleness and the lactic and mandelic picks climb; keep our weighting and the 2% BHA earns its top spot on performance and pedigree.

Frequently asked questions
- What is the difference between AHA and BHA?
- AHAs like glycolic and lactic acid are water-soluble and work on the skin surface, best for dryness, dullness, and sun damage. BHA, mainly salicylic acid, is oil-soluble and gets into pores, best for oily, congested, or blemish-prone skin.
- How often should I exfoliate?
- Start two to three times a week and adjust. Daily use is fine for some skin with a gentle formula, but over-exfoliation causes stinging, redness, and a compromised barrier. More is not better.
- Why does the right pH matter?
- AHA and BHA exfoliants need a pH around 3 to 4 to work properly. Well-formulated products are made within that range, which is part of why a thoughtfully formulated exfoliant outperforms a higher-percentage one with the wrong pH.
- Can I use an exfoliant with retinol or vitamin C?
- Cautiously. Alternate them on different nights when starting, since stacking strong actives raises irritation risk. Once your skin is used to each, some people combine them, but build up slowly.
