AHA-BHA-PHA 30 Days Miracle Serum
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
The name promises an exfoliating treatment, but the ingredient list tells a different story: the AHA, BHA and PHA acids are each present at a few thousandths of a percent, and salicylic acid is not in the formula at all, so this will not meaningfully exfoliate. What it does deliver is a well-dosed 14.5% centella extract with niacinamide in a pleasant, oil-cushioned base for the appearance of a calmer, less-reactive complexion. Buy it for the soothing base, not for the acids in its name.
- Cheap to use, about $4 a month
- 1 listed active is fairy-dusted below the 1% line

- Potency19 / 25
Dosed at studied levels, not fairy-dusted
- Centella Asiatica (Cica) (14.5%): dosed at a studied level
- Niacinamide: dosed at a studied level
- Glycolic Acid (~0.0003%): below the 1% line, treated as fairy-dusted
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.

What a month of use costs vs. the category
- About $4 per month to use
- $24 for 50 ml, used about once a day (about 0.3 ml each time), so a bottle lasts about 5.6 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 |
|---|---|---|
| Centella Asiatica (Cica) | 14.5% | Studied |
| Niacinamide | n/a | Studied |
| Glycolic Acid | ~0.0003% | Below 1% line |
A biphasic ampoule-serum with a plant oil layer (olive, camellia, rice bran and rosehip oils) sitting over a water phase built on 14.5% centella asiatica extract and niacinamide, in a dark tinted dropper bottle you shake before use. Despite the AHA-BHA-PHA name, the disclosed exfoliating acids sit at trace levels: glycolic acid and lactic acid are each listed at 3,000ppb, a few thousandths of a percent, and salicylic acid, the ingredient that would actually supply the BHA, does not appear on the INCI at all. The real actives here are the centella extract and niacinamide. The acid trio in the name is closer to a naming exercise than a formulation one.
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.

What the research says
In a controlled trial, a Centella asiatica cream was linked with a better looking, more even scar appearance over 12 weeks.

Topical 5% niacinamide was linked to more even looking skin tone, softer looking lines, and less visible blotchiness after 12 weeks.

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