Study case: Hyaluronic acid and the 60-day trial

Hyaluronic acid is the most familiar name on a serum label, and the ingredient with the most published research behind it. This study case looks at one well-cited trial, what it measured, and what it can and cannot tell you about any particular bottle, including ours.

What it is

Despite the word “acid,” hyaluronic acid (HA) is a moisturizing ingredient, not an exfoliant like glycolic or salicylic acid. It is a humectant: it attracts and holds water at the skin’s surface. The American Academy of Dermatology lists it, alongside ceramides, as an ingredient to look for in moisturizing products. AAD moisturizer guide.

HV1 + Peptides contains 1% hyaluronic acid.

The study

Pavicic and colleagues published a randomized, vehicle-controlled trial in the Journal of Drugs in Dermatology in 2011. Pavicic et al., 2011.

• Who: 76 women aged 30 to 60 with wrinkles around the eyes.
• What they used: a cream with 0.1% hyaluronan on one eye area and a vehicle cream (no HA) on the other, twice daily for 60 days.
• What varied: the molecular weight of the HA, tested at 50, 130, 300, 800 and 2000 kDa.
• What was measured: skin hydration, elasticity, and wrinkle roughness from skin replicas, at baseline, day 30 and day 60.

What it found

All of the HA creams improved hydration and elasticity significantly compared with the vehicle. Wrinkle-roughness measures improved significantly at day 60 for the 50 kDa and 130 kDa creams. The authors concluded that lower-molecular-weight HA was associated with the wrinkle-depth change, possibly because smaller molecules penetrate better.

What it does not tell you

A study is only as useful as its fit with the product in your hand. Read this one with these limits in mind:

• It tested a cream with 0.1% HA, not a serum with 1%.
• It measured the area around the eyes in women aged 30 to 60.
• Several authors are affiliated with companies that make hyaluronic acid.
• It did not test HV1 + Peptides. HV1 is new, and we do not have finished-product studies yet.

How we read it

The most consistent finding is the simplest one: topical HA is studied for hydration, and hydration is what makes skin look smoother and more supple. That is the expectation we set for HV1, with continued daily use over weeks. Apply it to damp skin after washing, which is also the AAD’s guidance for moisturizers.
