PRP treatment uses the patient's own blood plasma, rich in growth factors, to stimulate natural skin and tissue regeneration. It improves skin tone, texture and quality, contributes to a fresher and healthier appearance, and can be used on the face, under-eye area and scalp, as well as in various regenerative treatments. A series of 3 treatments at 4- to 6-week intervals is usually recommended, followed by maintenance every few months.
