Abstract: The present invention provides a non-therapeutic cosmetic method for treating a skin surface, said method comprising the combination of a medium with ultrasound waves, wherein the medium includes a suitable cosmetic product.
One aspect according to the present invention provides a non-therapeutic cosmetic method for reducing wrinkles on a skin surface, the method comprising the steps of applying an ultrasound transmission medium onto the skin surface to be treated, wherein the medium includes cosmetic actives/formula and applying ultrasound waves to the skin surface with the applied medium. The ultrasound waves produce acoustic output. The ultrasound waves have a frequency of 10 KHz to 50 MHz, preferably 30 KHz to 20 MHz, and more preferably 1 MHz to 10 MHz. The ultrasound waves are generated so that the ultrasound waves propagate in the skin to a maximum depth of 3 mm from the skin surface and generate a rise in temperature of the skin at the application zones.
