The Glow Maker
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
The value story of the vitamin-C aisle: the same strong-evidence antioxidant trio as the category benchmark for around a sixth of the price. It is not the identical formula and it will still brown on you eventually. As a first serious vitamin C, though, it is very hard to argue with.
- Evidence24 / 30
Strength of the research behind the key actives
- Vitamin C (L-Ascorbic Acid): strong evidence
- Vitamin E (Tocopherol): moderate evidence
- Ferulic Acid: moderate evidence
The average of the key actives’ evidence grades.
- Potency21 / 25
Dosed at studied levels, not fairy-dusted
- Vitamin C (L-Ascorbic Acid) (15%): dosed at a studied level
- Vitamin E (Tocopherol): dosed at a studied level
- Ferulic Acid: dosed at a studied level
How strongly the actives are dosed, led by the strongest, not how many there are.
- Delivery & stability12 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: standard
- Packaging: tinted glass
- Air- or light-sensitive actives (Vitamin C (L-Ascorbic Acid), Vitamin E (Tocopherol), Ferulic Acid), so packaging is scored.
Delivery tech plus packaging, and packaging only counts when actives are fragile.
- Formulation7 / 10
Disclosure, active breadth, and ingredient generation
- 1 of 3 actives disclose a concentration
- 3 key actives (breadth credit caps at 3)
- Current-generation or synergistic: Vitamin C (L-Ascorbic Acid), Vitamin E (Tocopherol), Ferulic Acid
Disclosure, active breadth, and current-generation or synergistic actives.
- Value12 / 15
What a month of use costs vs. the category
- About $20 per month to use
- $33 for 30 ml, used about twice a day (about 0.3 ml each time), so a bottle lasts about 1.7 months
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 |
|---|---|---|
| Vitamin C (L-Ascorbic Acid) | 15% | Studied |
| Vitamin E (Tocopherol) | n/a | Studied |
| Ferulic Acid | n/a | Studied |
An openly CE-Ferulic-inspired formula: 15% L-ascorbic acid with vitamin E and ferulic acid, plus hyaluronic acid and niacinamide for slip and finish. The antioxidant trio is the same idea as the ~$180 original at a fraction of the price; what you give up is disclosure on the E and ferulic levels and the reassurance of brand-name stability testing. It ships in an amber tinted-glass dropper, with the same oxidation caveat as every L-ascorbic serum.
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
A 6-month double-blind trial found topical vitamin C linked to a better looking global appearance of photoaged skin versus placebo.
Topical ascorbic acid on photoaged skin. Clinical, topographical and ultrastructural evaluation: double-blind study vs. placebo. Experimental Dermatology, 2003. PubMed ↗
A dermatology review describes topical vitamin E as an antioxidant linked to smoother, better moisturized looking skin in limited human studies.
Vitamin E in dermatology. Indian Dermatology Online Journal, 2016. PubMed ↗
A study of the active, not this exact product. What matters for the score is whether this serum uses it at a comparable dose.
