Payot Roselift Collagène Concentré Redensifying Booster Serum 30ml was specially developed to provide an intense and efficient redensifying and lifting action to mature skin. On one side, this dual-action serum resorts to a patented active ingredient derived from Damask Rose. The Roseactive helps to slow down the aging process by boosting the cellular metabolism of the support tissues and skin’s fibroblasts. To complement this action, the Roselift Collagène Concentré also contains a Collagen-Boosting Peptide that not only stimulates collagen production but also works as a redensifying agent. The result? According to the brand, with regular application, you will enjoy skin that appears plumper and firmer.
