PRP or platelet-rich plasma is prepared by drawing a sample of blood from one’s arm, spinning it in special machine to concentrate it in a defined fashion. This solution can be injected into the face or desired part of the body. Through release of special cytokines and proteins, PRP works to rejuvenate the skin while enhances the texture and volume. In addition to its regenerative effect on appearance and health of the skin, there is evidence of efficacy of PRP injection for hair growth in men and women with thinning hair (androgenic alopecia).
