DIVE-IN Low Molecular Hyaluronic Acid Serum
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
A well-built, fragrance-free hydration serum that delivers on its one real promise: layered hyaluronic acid for the look of plumper, dewier skin. The centella and ceramide mentions in the marketing are real but minor inclusions, not disclosed actives, so buy it for the HA network, not the extras. Fairly priced for a multi-weight HA serum.
- Cheap to use, about $9 a month
- No active concentrations are disclosed
- Evidence21 / 30
Strength of the research behind the key actives
- Hyaluronic Acid: moderate evidence
- Centella Asiatica (Cica): moderate evidence
- Ceramides: moderate evidence
The average of the key actives’ evidence grades.
- Potency20 / 25
Dosed at studied levels, not fairy-dusted
- Hyaluronic Acid: dosed at a studied level
- Centella Asiatica (Cica): present, but below a studied dose
- Ceramides: present, but below a studied dose
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: clear dropper
- 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 3 actives disclose a concentration
- 3 key actives (breadth credit caps at 3)
- Current-generation or synergistic: Centella Asiatica (Cica)
Disclosure, active breadth, and current-generation or synergistic actives.
- Value14 / 15
What a month of use costs vs. the category
- About $9 per month to use
- $24 for 50 ml, used about twice a day (about 0.3 ml each time), so a bottle lasts about 2.8 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 |
|---|---|---|
| Hyaluronic Acid | n/a | Studied |
| Centella Asiatica (Cica) | n/a | Light |
| Ceramides | n/a | Light |
Five molecular weights of hyaluronic acid, sodium hyaluronate, hydrolyzed hyaluronic acid, sodium acetylated hyaluronate, a crosspolymer and a hydrolyzed sodium salt, built into a layered hydration network with panthenol and trehalose, in a clear squeeze-dropper bottle. Madecassoside and madecassic acid (centella) and a small ceramide NP and cholesterol addition sit well down the ingredient list, undisclosed, so they read as supporting texture rather than a second or third dosed active. The multi-weight HA blend is the genuine hero and, as usual for this style of claim, is not disclosed as one single percentage. None of it is fragile.
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
A multicenter study linked a topical hyaluronic acid serum with better looking hydration, tone, and texture over several follow up visits.

In a controlled trial, a Centella asiatica cream was linked with a better looking, more even scar appearance over 12 weeks.

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