French skincare brand Caudalie has partnered with Harvard Medical School to launch Premier Cru the Serum, an extension of its existing Premier Cru range.

The serum was developed over a period of five years with Dr David Sinclair, a world-leading anti-ageing specialist and genetics professor at Harvard Medical School.

It contains three patented Caudalie ingredients: Vine Resveratrol, to plump and firm the skin, Viniferine, to even skin tone, and antioxidant-rich Polyphenols, derived from grape seeds. It also has a high-concentration of hyaluronic acid to help the skin maintain hydration levels.

In addition the serum contains Vinergy, a new patent, developed with Dr Sinclair, to target ageing cells, which produce less energy as the metabolism slows. Vinergy is a complex that combines Vine Resveratrol and naturally derived Betaine, which is designed to effectively combat the signs of ageing by increasing cellular energy metabolism and mitochondrial mass, as well as the production of ATP.

"Our groundbreaking discovery of Vinergy helps to restore the cell’s mitochondrial mass and energy production which in turn allows our cells to defend against ageing,” says Dr Sinclair. “Together, we’ve discovered a solution to counteract the diminishing energy metabolism of our cells over time, which is a key reason our skin ages."

The serum also improves the efficacy of other products in the Premier Cru range, including Premier Cru the Cream, which clinical trials found to be several times more effective when used with the serum.
