Mandelic Acid 10% + HA
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
The gentle end of the acid aisle, honestly dosed and cheap. The evidence for mandelic is thinner and younger than for glycolic or lactic, so treat it as a patient, low-drama pick rather than the strongest resurfacer.
- Mandelic Acid dosed at a clinical, high-end level
- Cheap to use, about $5 a month
- Evidence21 / 30
Strength of the research behind the key actives

Dosed at studied levels, not fairy-dusted
- Mandelic Acid (10%): dosed at a clinical, high-end level for its category
- Hyaluronic Acid: dosed at a studied level
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.
Delivery tech plus packaging, and packaging only counts when actives are fragile.

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

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Mandelic Acid | 10% | Clinical |
| Hyaluronic Acid | n/a | Studied |
10% mandelic acid, disclosed, over hyaluronic acid for slip, in a frosted glass dropper. Mandelic is the largest of the common AHAs, so it penetrates slowly and is usually the mildest-feeling option, aimed at the appearance of an even, clearer-looking tone.
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 mandelic acid use was linked to firmer, more elastic looking lower eyelid skin after 4 weeks of twice daily use.
Effects of Topical Mandelic Acid Treatment on Facial Skin Viscoelasticity. Facial Plastic Surgery, 2018. PubMed ↗
A multicenter study linked a topical hyaluronic acid serum with better looking hydration, tone, and texture over several follow up visits.

A study of the active, not this exact product. What matters for the score is whether this serum uses it at a comparable dose.
