Benefits of technology

[0010] In another embodiment, the protruding elements are provided with sharp tips that allow the elements to penetrate into the skin. After application of the RF current in the skin, the protruding elements are pressed into the skin and an electrical current is then generated that coagulates tissue in the vicinity of the tip of each protruding element. The mechanical properties of the skin are changed after coagulation and the protruding elements may penet

Problems solved by technology

The main disadvantages of skin resurfacing are the long healing period that can be over a month long and the high risk of dischromia.
These disadvantages have reduced the popularity of ablative skin resurfacing in recent years.
However, most wrinkle treatment methods target the collagen and do not have a significant effect on deep wrinkles.
Although a non-ablative treatment is much safer and does not scar the skin tissu

Embodiment Construction

[0025]FIG. 1 shows a system for applying RF energy to a plurality of discrete regions of skin in accordance with the invention. The system includes an applicator 13, to be described in detail below, configured to apply RF energy simultaneously to a plurality of discrete regions of skin of an individual 22. The applicator 13 is connected to a control unit 11 via a cable 12. The control unit 11 includes a power source 18. The power source 18 is connected to an RF generator 15 that is connected to electrodes in the applicator 13 via wires in the cable 12. The control unit 11 has an input device such as a keypad 10 that allows an operator to input selected values of parameters of the treatment, such as the frequency, pulse duration and intensity of the RF energy. The control unit 11 optionally contains a processor 9 for monitoring and controlling various functions of the device.

[0026]FIG. 2 shows an applicator 13a that may be used for the applicator 13 in accordance with one embodiment...

Abstract

A system and method for simultaneously heating a plurality of discrete skin volumes to a coagulation temperature. The system comprises an applicator containing an electrode having a plurality of spaced apart protruding conducting elements configured to contact the skin surface at a plurality of discrete locations. A controller applies a voltage to the electrode so as to simultaneously heat a plurality of skin volumes to a coagulation temperature when the applicator is applied to the skin surface.

Description

FIELD OF THE INVENTION [0001] The invention relates to methods and systems for skin treatment. BACKGROUND OF THE INVENTION [0002] Directed damage of the skin is used to stimulate regrowth of collagen and to improve skin appearance. A well known method of directed damage is ablating the epidermis using laser radiation having wavelengths strongly absorbed by water so as to heat the water to above boiling temperature. Typical lasers used for epidermis ablation are CO2 and Er:YAG lasers. Ablating the epidermis using RF (radiofrequency) current is described in U.S. Pat. No. 6,309,387. This treatment significantly reduces wrinkles and improves the skin appearance. The main disadvantages of skin resurfacing are the long healing period that can be over a month long and the high risk of dischromia. These disadvantages have reduced the popularity of ablative skin resurfacing in recent years. [0003] Non-ablative skin resurfacing is based on heating of the dermis to a sub-necrotic temperature w...
