The present invention relates to a skin treatment device, and more particularly, to a portable type photo skin treatment device using ultraviolet light.

In general, light from the sun has many kinds and characteristics, and light that has a deep influence on human beings and living things includes visible light visible to the eye, infrared light visible to the outside of red, and ultraviolet light outside to violet. .

The wavelength range of the ultraviolet ray is 400 nm (1 nm = 7-10 cm), which is 100 nm-280 nm in the wavelength band of ultraviolet C (UV-C (short wave), 280 nm-315 nm in the outer band B (UV-B)). Medium wave), 315nm-400nm is divided into ultraviolet A (UV-A (long wave)).

Ultraviolet C is very strong in destroying cells and bacteria, but the wavelength is short, so the penetration is weak, so most of them are absorbed by ozone layer and stratosphere. The main cause of skin damage caused by sunlight is UVB, which causes skin burns, pigmentation, bacterial infections, and even cancer. Ultraviolet UVA is only 1 / 1000th more energy-intensive than UVB, but the amount of light reaching the earth is about 100 times greater than UVB. Using such ultraviolet rays A, B, C, etc., sterilizers, treatment devices, and the like have been developed.
