Lactic Acid 10% + HA
Reviewed by SerumTruth Editorial · Updated July 2026
A genuine leave-on exfoliating serum at a throwaway price, with the acid level right on the label. A smart first AHA for skin that finds glycolic too sharp.
- Evidence21 / 30
Strength of the research behind the key actives
- Lactic Acid: moderate evidence
- Hyaluronic Acid: moderate evidence
- Score is the average of the key actives’ evidence grades.
- Potency21 / 25
Dosed at studied levels, not fairy-dusted
- Lactic Acid (10%): dosed at a studied level
- Hyaluronic Acid: dosed at a studied level
- Potency tracks 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: tinted glass
- No fragile actives here, so packaging barely moves the score.
- Formulation4 / 10
Disclosure, active breadth, and ingredient generation
- 1 of 2 actives disclose a concentration
- 2 key actives (breadth credit caps at 3)
- No current-generation or synergy bonus
- Value15 / 15
What a month of use costs vs. the category
- About $3 per month to use
- $9 for 30 ml, used about once a day (about 0.3 ml each time), so a bottle lasts about 3.3 months
- Frequency is set by Lactic 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 |
|---|---|---|
| Lactic Acid | 10% | Studied |
| Hyaluronic Acid | n/a | Studied |
10% lactic acid, disclosed, buffered with hyaluronic acid and a Tasmanian pepperberry anti-irritant, in a frosted glass dropper. Lactic is a larger, milder AHA that doubles as a humectant, so this leans gentler than a glycolic at the same strength while still doing surface work.
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.
