Hyalu B5 Serum
Reviewed by SerumTruth Editorial · Updated July 2026
A pharmacy-standard hydrator that does the comfort job well and is priced above the bargain HA serums for the finish and the brand. Be clear on what it is: the look of hydration and calm, not anti-aging. If you want a reliable, fuss-free hydrating layer, it delivers.

- Potency20 / 25
Dosed at studied levels, not fairy-dusted
- Hyaluronic Acid: dosed at a studied level
- Panthenol: dosed at a studied level
- Madecassoside: present, but below a studied dose
- Potency tracks 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: tinted glass
- No fragile actives here, so packaging barely moves the score.

- Current-generation or synergistic: Panthenol, Madecassoside
- Value11 / 15
What a month of use costs vs. the category
- About $24 per month to use
- $40 for 30 ml, used about twice a day (about 0.3 ml each time), so a bottle lasts about 1.7 months
- Band: $6/month or less earns full marks, $60/month or more hits the floor.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Hyaluronic Acid | n/a | Studied |
| Panthenol | n/a | Studied |
| Madecassoside | n/a | Light |
Two molecular weights of hyaluronic acid with panthenol (vitamin B5) and a little madecassoside, in a tinted dropper bottle. It is a hydration and comfort serum aimed at the appearance of plumper, calmer-looking skin, not a tone or fine-line treatment. None of the actives are fragile, so packaging is not a concern here. It layers cleanly under moisturiser and sunscreen.
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.
