Abstract: Platelet-rich plasma (PRP) is a plasma fraction that contains a greater concentration of platelets, which is usually 4 to 7 fold of the mean platelet concentration of the whole blood. Platelet-rich plasma is rich in growth factors and can promote epithelialization, angiogenesis and collagen regeneration. This review mainly summarizes the application of platelet-rich plasma in discosmetic dermatoses, such as androgenetic alopecia, alopecia areata, scar, vitiligo, striae distensae and facial rejuvenation.

Key words: platelet-rich plasma, discosmetic dermatoses, facial rejuvenation
