A wrinkle, also known as a rhytide, is a fold, ridge or crease in the skin. Skin wrinkles typically appear as a result of aging processes such as glycation, habitual sleeping positions, loss of body mass, or temporarily, as the result of prolonged immersion in water. Age wrinkling in the skin is promoted by habitual facial expressions, aging, sun damage, smoking, poor hydration, and various other factors.
Radiofrequencies are commonly in used in medicine since the very beginning of the 20th century and proved to create a long lasting effect, due to continuous denaturation process (5% – 30% of total collagen fibers in the treated area) and the formation of a damaged area with an inflammatory component that induce finally a reparative response. The flogistic stimulation selects some important fibroblast’s subpopulations that have an important role in fibrosis formation and stimulation of production new collagen.
Generally the heat produced is developed gradually in 3mm to 9 mm depth and determines heating up to 55ºC – 65 ºC. Forma™ ST applicator is a bipolar pulsed radiofrequency with cooling system of the electrodes , able to deliver up to 100 J/cm³ in less than 200 ms. This fractional mode of energy delivery, generate an immediate peak of about 60ºC within the dermis layer. This results as a firmly effective stimulation for the consequent reparative desired response.
