Product details
A closer look.
Biologique Recherche Cocktail d'Actifs Régénérants is an intensive concentrate designed to visibly revitalize the skin, one vial at a time. This serum is over-boosted with 56 active ingredients developed using cutting-edge biotechnology and vitamins, for a visible, multi-action result across six benefits, even on the most devitalized-looking skin. Its formula brings together peptides, a copper peptide, a blend of 24 amino acids and a multivitamin complex including vitamin C, retinol, vitamin E, niacinamide and biotin, along with glutathione, coenzyme A and nicotinamide adenine dinucleotide. It helps reduce the appearance of fine lines and wrinkles, improves hydration and tone, and leaves the skin feeling smoother. The kit contains 10 vials for a total of 20 applications: each vial is good for two applications, applied one day and then the next. Refrigerate after opening.
Why you’ll love it.
When skin looks tired, dull and devitalized, we like having a concentrate that does several things at once. Cocktail d'Actifs Régénérants packs peptides, amino acids, vitamins and antioxidants into one vial, so it covers fine lines, hydration, tone and texture in a single step. We also love the format: each vial is split over two days, which makes it easy to follow as a focused course. It is a beautiful way to give a tired-looking complexion a visible boost.
