Pigmentbio C-Concentrate Serum
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
The glycolic acid and vitamin-C ester are dosed for real work on the look of dullness and rough texture, and the delayed-activation bottle is a legitimately clever fix for vitamin C's stability problem. The headline 'LumiReveal' azelaic acid and licorice combination is mostly a marketing hook, both come in at trace levels on the INCI. Treat it as a glycolic-plus-vitamin-C serum with a smart bottle, not a three-active pigmentation treatment, and price it accordingly.
- 1 listed active is fairy-dusted below the 1% line
- Evidence23 / 30
Strength of the research behind the key actives
- Glycolic Acid: strong evidence
- Sodium Ascorbyl Phosphate: moderate evidence
- Niacinamide: moderate evidence
- Azelaic Acid: moderate evidence
The average of the key actives’ evidence grades.
- Potency20 / 25
Dosed at studied levels, not fairy-dusted
- Glycolic Acid (8%): dosed at a studied level
- Sodium Ascorbyl Phosphate (2%): dosed at a studied level
- Niacinamide: dosed at a studied level
- Azelaic Acid: 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: clear dropper
- No fragile actives here, so packaging barely moves the score.
Delivery tech plus packaging, and packaging only counts when actives are fragile.
- Formulation6 / 10
Disclosure, active breadth, and ingredient generation
- 2 of 4 actives disclose a concentration
- 4 key actives (breadth credit caps at 3)
- Current-generation or synergistic: Sodium Ascorbyl Phosphate

- Value10 / 15
What a month of use costs vs. the category
- About $26 per month to use
- $44 for 15 ml, used about once a day (about 0.3 ml each time), so a bottle lasts about 1.7 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

A multi-acid brightening concentrate led by glycolic acid and a stabilized vitamin-C ester (Ascorbyl Glucoside, not disclosed by exact percentage but reported around 2%), with niacinamide as a supporting player. The much-marketed "LumiReveal" pairing of azelaic acid and glabridin (a licorice-root isoflavone) reads as the headline story, but both sit far down the INCI, past the point where formulas are typically dosed under 1%, more fairy dust than active treatment. The real engineering is in the bottle: an opaque cartridge keeps the vitamin C as a dry powder, activated and shaken into the liquid at first use, a genuinely sound way to dodge the oxidation problem that plagues most vitamin-C serums, even though the closest fit in a fixed packaging taxonomy is a plain clear dropper.
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
Topical glycolic acid was linked to a smoother, more evenly toned looking appearance in sun exposed skin in a small clinical study.

In human volunteers, a 5% sodium ascorbyl phosphate gel was linked to reduced looking crow's feet wrinkle depth and better skin elasticity.

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