With the present invention, it is possible to improve the cosmetic appearance of skin by controllably heating a superficial layer of skin thereby inducing acute tissue contraction or shrinkage and a wound response leading to the production of biomolecules, all of which result in improved cosmesis. The invention incorporates a source of radio frequency electrical energy coupled to coil, with requisite impedance matching network, thereby resulting in the production of an alternating magnetic field. When tissue is brought into proximity of the alternating magnetic field, inductive heating of the tissue results as a consequence of either or both of dipole formation and oscillation, and eddy current formation. Optionally, cooling is provided to remove heat from the coil, the source of radio frequency electrical energy, or the surface of the skin alone or in combination. The invention exhibits the significant benefits of, among other things, being non-invasive, not requiring electrical contact with the body of the subject, and providing controllable heating only to a thin layer of tissue. The invention is useful not only for cosmetic procedures such as facial rejuvenation, wrinkle treatment, acne treatment, hair removal, vascular lesion treatment, varicose vein treatment, curing of fillers, and treatment of cellulite, but also for surgical procedures such as coagulation, cauterization or for induction of biomolecular events such as a wound response, production of heat-shock proteins or an inflammatory response in tissue.La présente invention concerne lamélioration esthétique de la peau par chauffage contrôlé dune couche superficielle de peau, ledit chauffage induisant une contraction tissulaire aiguë ou retrait et une réaction aux blessures menant à la production de biomolécules, le tout aboutissant à lamélioration de laspect esthétique.
