With aging, the body produces less collagen and loses elastin, creating fine lines, wrinkles, and skin laxity. In-Depth Filler Serum is highly effective at treating skin aging in two different ways–by protecting fibers and enabling skin to produce more collagen and elastin. It improves skin density and firmness for a visible lift. Reduces the appearance of fine lines and wrinkles and enhances skin radiance. Boosts production of hyaluronic acid to remodel, firm, and tighten the skin. Enhances fibroblast production and dermal reconstruction to firm the skin. Protects from ECM fiber damage from glycation.
