Celimax The Vita A Retinal Shot Tightening Booster is an advanced anti-aging serum powered by retinal, a potent form of vitamin A that works faster than retinol to stimulate collagen production and accelerate cell turnover. This concentrated booster targets fine lines, wrinkles, sagging, and enlarged pores while improving overall skin firmness and elasticity. Retinal delivers visible tightening results with less irritation than traditional retinoids, making it suitable for those seeking effective age-defying care.
