Abstract

Apparatus and methods for electromagnetic skin treatment, including the removal of hair. Devices include pulsed light sources such as flashlamps for providing electromagnetic treatment of the skin, including hair removal. The devices and methods provide for the removal of large numbers of hairs at the same time, rather than on a hair by hair basis.

Claims

1. A medical treatment device for application of light to the skin, comprising:

a light source for creating a spatially dispersed field of light;

a power source for providing power to said light source; and

,

an optically transparent medium, said medium comprising a gel for contact with the skin to transmit said light to said skin.

2. A device as claimed in claim 1, wherein said medium comprises a transparent plate, and further comprises a gel beneath said transparent plate.

3. A device for improving the appearance of the skin, comprising:

a light source for generating optical radiation;

a contact device, said contact device comprising a first transparent medium for placement in contact with the skin for transmission of said optical radiation said first transparent medium comprising glass; and

a second optically transparent medium for placement between said contact device and the skin, to transmit optical radiation from said contact device to the skin, said second transparent medium comprising a gel.

4. A medical system for application of light to the skin, comprising;

an apparatus for producing a spatially extended field of light;

at least one element for focusing said spatially extended field of light; and

a transparent contact device comprising an optically transparent material for placement in contact with the skin for transmission of said light to the skin; and

a transparent medium for placement between said contact device and the skin and

an optically transmissive material for placement between said transparent contact device and the skin to transmit said light from said transparent contact device to the skin.
