It's called "needling" and is a technique of bio remodeling anti cellulite which stimulates the production of collagen. The process is organic: it utilizes the activation of mechanisms of self healing skin traumatized. Thus, controlled microtrauma, due to the penetration of microscopic needles of 1 mm placed on a cylindrical roller bearing, triggering cell repair and collagen production, equal to 200 percent after 6-8 weeks. The technique used in the United States to correct inestetisimi by scars and wrinkles, is now applied to stretch marks and cellulite like. "This method wakes up the atrophic tissue that is self regenerating," says Massimo Signorini, a plastic surgeon, head of the surgery of 'Instituto Milan European dermatology. "A month before treatment is important to take retinoids (vitamin A)." How does the needling? Anesthetic cream is applied and make repeated passes with the roller in the area that has cellulite, causing at least one bleeding and a sensation of swelling-tension at the end. The skin stays red for 3-4 days, while the effect begins to be seen after 2-3 month (in which the skin must be protected from the sun) and a maximum distance of 6-8 months.
