1 oz size of Progeskin serum, hermetically sealed (comes with dropper cap). My coworkers swear by it! Retails for $185. From BR: Progeskin addresses the visible signs of skin senescence with its advanced, dual-action formula. It helps the skin appear firmer, more toned, and resilient. Facial features are visibly smoothed, and the appearance of wrinkles and fine lines is reduced. The skin looks refreshed, younger, and more rested. #skincare #biologiquerecherche #luxury #antiaging #serum
