Good Genes All-In-One Lactic Acid Treatment
Reviewed by SerumTruth Editorial · Updated July 2026
The brand signature acid, a smooth lactic acid treatment aimed at the look of a brighter, smoother surface with less sting than glycolic. The undisclosed level and prestige price are the trade, and the dose reads gentle rather than strong. Pleasant to use daily, and it layers like a serum despite the treatment name.
- Evidence21 / 30
Strength of the research behind the key actives
- Lactic Acid: moderate evidence
- Score is the average of the key actives’ evidence grades.
- Potency21 / 25
Dosed at studied levels, not fairy-dusted
- Lactic Acid: dosed at a studied level
- Potency tracks how strongly the actives are dosed, led by the strongest, not how many there are.
- Delivery & stability16 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: standard
- Packaging: airless, opaque
- No fragile actives here, so packaging barely moves the score.
- Formulation1 / 10
Disclosure, active breadth, and ingredient generation
- 0 of 1 actives disclose a concentration
- 1 key active (breadth credit caps at 3)
- No current-generation or synergy bonus
- Value11 / 15
What a month of use costs vs. the category
- About $26 per month to use
- $85 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 | n/a | Studied |
A lactic acid treatment built on food-grade lactic acid with licorice root and stearyl glycyrrhetinate for the appearance of a more even tone, in an opaque white pump bottle. The percentage is not disclosed, and independent ingredient readers place it around the lower end of the leave-on AHA range, so it reads as a gentler daily acid rather than a peel. Lactic acid is stable, so the opaque pump is about dosing more than protection.
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.
