Modern equipment that uses electromagnetic energy to generate heat in the dermis tissue while the skin surface remains cool and protected. Heating the dermis and the hypodermis promotes an increase in the production of collagen and elastin. There is an increase in blood supply and vascularization in the area, decompressing the treated tissues. Radiofrequency is considered the best technology available to treat skin laxity, cellulite, stretch marks and tissue adhesion. The contraction of the collagen fibers promoted by the heat in the dermis also provides an immediate lifting effect so that the client can see smoother and tighter skin right in the first session. The production of neo-collagen will continue for weeks after the first application.
