Biologique Recherche has created Progeskin, a serum that combats skin aging, also known as senescence. Progeskin tackles this process through Progescence, which reduces the accumulation of senescent cells over time, and Pro-KL, which delays cellular senescence. This unique formula thus offers a dual action on the phenomenon of skin senescence. The skin becomes firmer, more toned, and plump. Facial features are smoothed, and wrinkles and fine lines reduced. The skin appears younger and more rested.
