Light radiation penetrates the skin, and the hair follicle, as the part with the most melanin deposition in the skin, absorbs the most light energy and converts it into heat energy, forming a higher temperature near the hair follicle. hair follicles, leading to inactivation of hair mother cells.
Step1: The xenon lamp of the epilator emits strong pulsed light.
Step2: The filter filters out harmful and useless wavelengths of light.
Step3: The effective light penetrates directly from the epidermis to the dermis.
Step4: The hair follicle melanin in the dermis absorbs light energy and generates heat.
Step5: Heat shrinks hair mother cells—hair follicle growth.
Step6: Hair growth is inhibited.
Step7: The hair becomes less, thinner and lighter.

Influencing factors of epilator
The main factors that affect the hair removal effect:
a. Different wavelengths penetrate the skin at different depths, and the effective wavelength is the wavelength that can affect the position of the hair follicle.
B. Hair follicles are mainly in the dermis, with a depth of about 1-3mm. It is recommended to choose a hair removal device with a wavelength greater than 600nm.
C. Young people under the age of 25 have a thicker dermis, so the depth of hair follicles is also deeper. It is recommended to choose a hair removal device with a wavelength of 640nm and above.

Whether it is IPL hair removal or laser hair removal, no matter what wavelength the light source is, part of the light will be absorbed by the skin, but the ratio is different, there is no difference. Light sources that the skin does not absorb at all

The area of the state filter is 640-1200NM,
The current common one is 510-1200NM,
The poorer ones are 475-1200NM
