Combined galvanic and pulsed optical energy for depilation
A method for photothermolysis that includes applying galvanic current energy to skin at an area of a hair follicle and applying pulsed optical energy to the skin at the area of the hair follicle at an energy level and duration so as to cause thermal destruction of a hair papilla.
1. A method for depilation or hair removal by photothermolysis that combines galvanic current energy and pulsed optical energy, the method comprising:
applying galvanic current energy to skin at an area of a hair follicle at a level incapable of destroying hair papilla, to open a pore around the hair follicle;
and applying pulsed optical energy to the skin at the area of the hair follicle with the open pore at an energy level and duration so as to cause thermal destruction of a hair papilla.
2. The method of claim 1 , wherein the galvanic current energy is continuous wave energy.
3. The method of claim 1 , wherein the open pore increases exposure of the hair follicle the optical energy.
4. The method according to claim 1 , wherein the pulsed optical energy comprises at least one of intense pulsed light (IPL) and pulsed laser energy.
5. The method according to claim 1 , wherein the pulsed optical energy is in a range of 2.5-40 J/cm 2 and has a pulse duration of 0.5-30 milliseconds.
6. The method according to claim 1 , wherein the pulsed optical energy comprises laser energy that has a wavelength in a range of 700-1100 nm.
7. The method according to claim 1 , wherein the pulsed optical energy comprises IPL that has a wavelength in a range of 450 nm-1200 nm.
