Abstract: A method for synergetic amplification of the standard effects of an essential oil with beneficent properties for the skin, the scalp, the nails and the hair, which consists in applying on the zone to be treated the desired essential oil or mixture of essential oils, and in subjecting said zone to the action of pulsed high frequency electromagnetic waves with frequency ranging between 1 MHz and 300 MHz, with a time spacing of 0.1 to 400 milliseconds between each wave impulse, and with a power of 10−6 W to 2 W, cosmetic treatment kit and pulsed athermal high frequency electromagnetic-wave generator with instructions for joint use to obtain amplified effects thereof.
