Bright Boost Illuminating Serum
Reviewed by SerumTruth Editorial · Updated July 2026
Much of the appeal is the instant, light-reflecting finish rather than a heavily studied active lineup. Neoglucosamine has a thinner, more brand-led evidence base than arbutin or tranexamic acid, and the turmeric reads as a supporting note rather than the main event. A reasonable glow-and-maintain pick, not a substitute for a serum built around better-evidenced dark spot actives.

Strength of the research behind the key actives
- Alpha Arbutin: moderate evidence
- Licorice Root (Dipotassium Glycyrrhizate): limited evidence
The average of the key actives’ evidence grades.
- Potency12 / 25
Dosed at studied levels, not fairy-dusted
- Alpha Arbutin: present, but below a studied dose
- Licorice Root (Dipotassium Glycyrrhizate): below the 1% line, treated as fairy-dusted
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.
Delivery tech plus packaging, and packaging only counts when actives are fragile.
- Formulation3 / 10
Disclosure, active breadth, and ingredient generation
- 0 of 2 actives disclose a concentration
- 2 key actives (breadth credit caps at 3)
- Current-generation or synergistic: Alpha Arbutin

- Value13 / 15
What a month of use costs vs. the category
- About $15 per month to use
- $24.99 for 30 ml, used about twice a day (about 0.3 ml each time), so a bottle lasts about 1.7 months

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Alpha Arbutin | n/a | Light |
| Licorice Root (Dipotassium Glycyrrhizate) | n/a | Below 1% line |
The marketed actives are Neoglucosamine (acetyl glucosamine, graded here against alpha arbutin as the closest tone-focused analogue) and turmeric extract (graded against licorice root as the closest gentle, plant-derived brightener), not either ingredient this scoring model is built around. Acetyl glucosamine sits high on the ingredient list and is likely at a meaningful level; turmeric extract and a second brightening ingredient, hexylresorcinol, both fall after the carbomer thickener, typical fairy-dust territory. Mica and titanium dioxide near the end give it an immediate soft-focus glow that is separate from any longer-term tone effect. It comes in an opaque pump bottle.
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.
