Method and device for collagen growth stimulation
View Patent ↗The invention provides an applicator for skin treatment having one or more RF electrodes. An article is located between the electrodes, such as a roller or flexible belt containing one or more protruding pins electrically isolated from the RF electrodes. The invention also provides a system for skin treatment comprising the applicator of the invention and a control unit. The invention further provides a method of treating skin disorders in which a section of the skin is heated while, essentially simultaneously, piercing one or more holes in the heated section of the skin. The method of the invention may be used, for example, in collagen remodeling.
1. A system for skin treatment, comprising:
(a) an applicator for skin treatment, comprising:
i) one or more RadioFrequency (RF) electrodes configured to be applied to skin surface; and
ii) an article located between the electrodes, said article containing one or more protruding pins comprising one or more isolating or dielectric materials having a resistance greater than the skin resistance and electrically isolated from the RF electrodes, and operative to puncture and penetrate the skin; and
(b) a control unit.
2. The system according to claim 1 , wherein the article is made of electrically isolating material.
3. The system according to claim 1 , wherein the protruding pins of the article are made from at least one member selected from the group consisting of metal, plastic, and a composite material.
4. The system according to claim 1 , wherein the length of the pins is in a range of from 0.1 mm to 3 mm and the diameter of the pins is less than 0.5 mm.
5. The system according to claim 1 , wherein the pins are designated to penetrate the skin.
6. The system according to claim 1 , wherein the applicator further comprises a light source.
7. The system according to claim 6 , wherein the light source is at least one member selected from the group consisting of an incandescent lamp, a flash lamp, a LED, and a laser.
8. The system according to claim 6 , wherein the light source is arranged to illuminate the skin between the electrodes.
9. The system according to claim 1 , wherein the RF electrodes communicate with a source of cooling fluid.
10. The system according to claim 1 , wherein the control unit further comprises:
(a) a source of RF energy;
(b) a light emitting unit power supply; and
(c) a source of cooling fluid.
11. The system according to claim 10 , wherein the source of RF energy and the source of cooling fluid communicate with the one or more RF electrodes.
12. The system according to claim 10 , wherein the light emitting unit power supply communicates with a light source.
