PRP is increasingly used in\u00a0cosmetic surgery<\/a>\u00a0and in\u00a0plastic surgery<\/a>\u00a0for its regenerative qualities.
\nthe\u00a0PRP<\/strong>, abbreviation of\u00a0Platelet rich plasma<\/strong>, is a product obtained by centrifugation of a small quantity of its own blood taken from the bend of the elbow. This blood extract is a concentrate of platelets; the latter have regenerative and healing properties.<\/p>\n

What are the indications for this treatment?<\/h2>\n

SKIN REJUVENATION<\/u>
\nSkin aging<\/strong>\u00a0leads to a decrease in the quantity and quality of the proteins that structure the skin. These proteins are secreted by the fibroblasts and are essentially represented by the collagen responsible for the thickness and the solidity of the skin and the elastin which ensures the flexibility of this one. Animal and fibroblast culture studies show that PRP significantly improves dermis quality and collagen secretion (1, 2,3).
\nInjection under the skin by micro-injection in the form of mesotherapy or by microcannulas corrects the signs of aging, improves skin texture and smoothes skin fine lines. The result is obtained after 2 or 3 sessions.<\/p>\n

THE TREATMENT OF ALOPECIA<\/u>
\nPRP has long been used to prevent hair loss or to promote regrowth after alopecia. These treatments were based on some animal studies showing hair regrowth (4). However, even if these treatments seemed effective, no study allowed to affirm a real benefit. The British Journal of Dermatology recently published a randomized clinical trial using PRP injections against a placebo. This study of great scientific value shows a significant advantage of PRP injections for the treatment of certain alopecia (5).
\nIt is recommended to perform 3 injection sessions 15 days apart to obtain an improvement in scalp densification.<\/p>\n
