Vitamin C Serum
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
A gentle, low-irritation vitamin C for reactive skin, using the stable SAP form with supporting antioxidants. The evidence for the derivative is lighter than for L-ascorbic acid and the level is undisclosed. As an easygoing daily antioxidant at an indie price, it is easy to recommend.

- Delivery & stability12 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: standard
- Packaging: tinted glass
- Air- or light-sensitive actives (Vitamin E (Tocopherol), Ferulic Acid), so packaging is scored.
Delivery tech plus packaging, and packaging only counts when actives are fragile.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Sodium Ascorbyl Phosphate | n/a | Studied |
| Vitamin E (Tocopherol) | n/a | Studied |
| Ferulic Acid | n/a | Studied |
Built on sodium ascorbyl phosphate, a stable water-soluble vitamin C salt, with vitamin E, ferulic acid, hyaluronic acid and a few botanical extracts, in a frosted-glass dropper. SAP does not sting or oxidise the way L-ascorbic acid does, so the frosted glass is not the liability it would be for the acid form. The percentage is not disclosed, though the vitamin C sits high on the list.
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 human volunteers, a 5% sodium ascorbyl phosphate gel was linked to reduced looking crow's feet wrinkle depth and better skin elasticity.

A dermatology review describes topical vitamin E as an antioxidant linked to smoother, better moisturized looking skin in limited human studies.

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