Glycolic Acid 7% Exfoliating Toner
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
The value floor for a glycolic toner: a disclosed, sensible daily dose in a bottle that lasts for months. Glycolic raises sun sensitivity, so daytime sunscreen is part of the deal.
- Built on strong-evidence actives
- Every active discloses its concentration
- Cheap to use, about $3 a month

How strongly the actives are dosed, led by the strongest, not how many there are.
- Delivery & stability14 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: standard
- Packaging: clear dropper
- No fragile actives here, so packaging barely moves the score.
Delivery tech plus packaging, and packaging only counts when actives are fragile.

What a month of use costs vs. the category
- About $3 per month to use
- $13 for 240 ml, used about once a day (about 1.75 ml each time), so a bottle lasts about 4.6 months
- Frequency is set by Glycolic Acid, which is used no more than 7x a week, so a bottle stretches further
What a month of use costs: full marks at $6 a month or less, the floor at $60 a month or more.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Glycolic Acid | 7% | Studied |
7% glycolic acid, disclosed, with aloe, ginseng and Tasmanian pepperberry as anti-irritants, in a large clear glass bottle you pour from. It is a daily exfoliating toner, not a serum, and the 7% sits inside the studied leave-on range for the appearance of a smoother, brighter surface.
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.
The actives, explained
What the research says
Topical glycolic acid was linked to a smoother, more evenly toned looking appearance in sun exposed skin in a small clinical study.
Improving the cosmetic appearance of photoaged skin with glycolic acid. Journal of the American Academy of Dermatology, 1997. PubMed ↗
A study of the active, not this exact product. What matters for the score is whether this serum uses it at a comparable dose.
