normal wound healing process. Such factors coordinate the processes of epithelialisation, angiogenesis, and collagen-matrix formation, the key steps in the wound healing sequence. Growth factors function in paracrine, endocrine, and
autocrine manners in order to guide the dynamic stages of wound healing. No single growth factor appears to maintain a total physiologic task, but instead these peptides work in a coordinated fashion to orchestrate the normal wound healing processes. Besides the initiation of coagulation processes, the
platelets undergo a degranulation process which releases a complex group of growth factors and cytokines (peptides) essential for wound-healing mechanisms. In Table 1, it is possible look at the different actions of
the platelet-derived growth factor over the extracellular matrix and tissue maturation, against the free radicals, and in relation to angiogenesis and epithelisation. PRP under the concentration of the growth factors

gives a strong and autologous medicine for the fibroblast stimulation, helps the recovery of the ECM, increases the angiogenesis and helps the recovery of the skin with the production of collagen. This is a process of biostimulation and is the main motivation for the PRP. Biostimulation activates the biological functions of the skin with the purpose of optimising its physiology and consequently leading to aesthetic improvement. This is part of the author’s base treatment in all cases of cellulite.

Obtaining PRP There are many kits for obtaining PRP. In the author’s opinion the best kits have gel inside the tubes to allow a perfect separation between blood, white inflammatory cells, and plasma.

The author’s preferred kit to take PRP are the tubes that have gel inside to allow a perfect separation between blood, white blood cells, and the platelets after a
special centrifugation. They also allow for a larger amount of PRP to be taken.
