The role of local retinoids in eliminating signs of skin aging

Skin aging is a complex process involving both internal (chronological aging) and external (biological aging) factors.Slowing down the Beauty proliferative and immune processes in the epidermis, reducing the activity of fibroblasts and vascularization of the dermis during chronological aging lead to thinning, dryness, hypersensitivity, vulnerabilit
