A study put numbers to something we already suspected
For years, resveratrol was sold as just another ingredient in a cream. In December 2025, a clinical trial published in *Frontiers in Aging* (Healthy Longevity section) provided concrete data for something we at VitaVigne already intuited: resveratrol does not act the same alone as it does when combined.
The study worked with 134 healthy women, all over 40 years old, for 8 weeks. There were four groups: placebo, oral resveratrol only, topical resveratrol only, and a fourth group that combined both — capsule and cream, twice a day.
What they found
Only the group that combined the two forms showed a significant reduction in wrinkles compared to placebo. The groups that used resveratrol through a single pathway did not achieve the same result. The trial also evaluated safety, and no relevant adverse events were recorded in any group.
- **Oral resveratrol only:** no significant difference compared to placebo
- **Topical resveratrol only:** no significant difference compared to placebo
- **Oral + topical resveratrol:** significant reduction in wrinkles
Why it makes sense at a cellular level
Resveratrol activates sirtuins, proteins linked to cellular repair. But sirtuins need NAD+ to do their job, and NAD+ is precisely what the body loses with age. That's why a formula that combines NMN —a direct precursor to NAD+— with resveratrol is no coincidence: one replenishes the fuel, the other activates the engine.
It's the same logic that this study has just confirmed for the skin: the oral pathway and the topical pathway do not compete with each other. They complement each other.
The protocol we were already upholding
At VitaVigne, we never thought of the serum and the supplement as two separate products, but as a single protocol with a single origin: the antioxidant power of grapes. The same resveratrol that protects these high-altitude vines reaches your skin through the Vine Essential Serum, and your body through our NMN + Resveratrol supplement, formulated under European standards.
At VitaVigne, we believe that science does not replace intuition. It confirms it.
