Patent ID: 8457751

Claim:
A cosmetic method of treating skin ageing, comprising the following steps: a) connecting a device for treating skin ageing, the device comprising: one or more electrodes of essentially laminar shape, to be applied on the skin by adherence and connected to an electronic device, said electronic device comprising: a rectifier circuit fed by a power grid voltage which supplies a voltage, to a radiofrequency circuit; the radiofrequency circuit comprising at least an electronic switch fed by said voltage and piloted by a piloting circuit, wherein said radiofrequency circuit output consists of a current wave of distorted sinusoidal form by the presence of harmonics of at least the second and third order, said resultant wave circulating in a broadband resonant circuit on the frequency of the pure wave of said distorted sinusoidal form; b) applying said one or more electrodes on the skin surface in the area to be treated; c) activating said electronic device in order to transfer said current waves to said one or more electrodes and to maintain said device activated for a predetermined time; d) deactivating said device and removing the electrodes from the contact with the treated area.
