The clinical application of platelet-rich plasma (PRP) is based on the increase in the concentration of growth factors that are released from alpha-granule of the concentrated platelets and in the secretion of proteins which are able to capitalize on the healing process at the cellular level. It has been invented to restore the natural beauty by starting the natural rejuvenation process of the skin and aiming to make it function as a younger one and to keep the skin youthful and maintain it. Besides that, it is also emerged to include hairs as a new injectable procedure to enable stimulating hair growth locally and topically; preventing its fall; improving hair shaft, hair stem, and its caliber; increasing its shine, vitality, and pliability; and declining hair splitting and breakage. Thus, youth is in your blood as it has a magical power imposed in the platelet factors. There is, however, no standardization of the techniques besides insufficient description of the adopted procedures. Not long, autologous platelet-rich plasma (PRP) has surfaced strongly in diverse medical specialties including plastic, wound healing and diabetic ulcers, orthopedic, trauma, ocular surgery, dry eye for eyelid injection, urology for urinary incontinence, sexual wellness, cutaneous surgery, sport medicine, dentistry and dermatology, and aesthetic applications. PRP proved to promote wound healing and aid in facelift, volumetric skin, skin rejuvenation, regeneration, and reconstruction; improve wrinkling; stimulate hair growth; increase hair follicle viability and its survival rate; prevent apoptosis; increase and prolong the anagen hair growth stage; and delay the progression to catagen hair cycle stage with increased density in hair loss and hair transplantation. The aims of this extensive review were to cover all PRP application aspects that are carried out in aesthetic dermatology and to assess the literature on platelet-rich plasma outcomes on main aesthetic practices of general dermatology. A literature review was conducted by searching through PubMed, Biomedical Library database, Google Scholar, and Research Gate for the terms PRP, platelet-rich plasma, platelet-rich fibrin matrix, platelet preparations, platelet application therapy, platelet growth factors, platelet facial, platelet facial rejuvenation, platelet hairs, and platelet wound healing, from inception till 2017, and they were combined using Boolean operators. All those retrieved articles in English language were looked at and explored thoroughly.
