Hyaluronic Acid 2% + B5
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
A hydration workhorse at a throwaway price: well-dosed, disclosed and exactly what it says. Just be clear on what it is not. This is the look of plumper hydration, not fine-line or tone work, and it is priced honestly for that.
- Hyaluronic Acid dosed at a clinical, high-end level
- Every active discloses its concentration

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Hyaluronic Acid | 2% | Clinical |
2% hyaluronic acid across a range of molecular weights with provitamin B5, disclosed, in a plain glass dropper. It is a humectant hydrator, full stop. It makes skin look plumper and dewier while it sits there and does not pretend to be an anti-aging active. Neither ingredient is fragile, so the clear dropper is a non-issue. In a dry climate, use it on damp skin and seal it, or HA can pull the wrong way.
Safety lens: every ingredient in this formula, graded on the safety evidence at PlainBody ↗, our sister site.
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 multicenter study linked a topical hyaluronic acid serum with better looking hydration, tone, and texture over several follow up visits.

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