810nm Diode Laser

What is 810nm diode laser hair removal?

The 810nm diode laser system uses a gold standard laser with a wavelength of 810nm, the diode laser emits near-infrared light waves that penetrate deep into the root of the hair follicle, heating the pigment in it and diffusing it throughout the entire hair follicle, which can precisely destroy the hair follicle without causing damage to adjacent tissues, achieving permanent hair removal.

During the treatment, it can also stimulate the collagen tissue of the skin, making the skin shiny, delicate, firm and elastic.

Suitable for all parts of the body, such as: face, lips, hands, back, chest, underarms, bikini line hair removal, legs.

Working theory

It is based on the principle of selective thermal effect: that is, the selected wavelength acts only on the melanin and not on the normal tissue of the skin; the selected pulse width acts only on the melanin in the hair follicle and not on the melanin in the basal layer of the skin.

Since the hair follicle has many melanin, it can preferentially absorb a large amount of laser energy and eventually convert it into heat energy, which will increase the temperature of the hair follicle and destroy its function.

In this process, the skin does not absorb the laser energy, or absorbs a very small amount of laser energy without causing any damage to the skin itself.

Hair cycles - anagen, recession and dormancy, hair follicles are most effective when they are in the anagen phase, but only 10-20% of the hair is in the anagen phase, so a course of treatment is required to completely remove the hair.

Q & A

1. Will the hairs get darker after epilation?

The hairs that are left after laser or intense light treatment will become finer and lighter in color and will not become darker. While shaving, plucking, hair removal cream, wax paper hair removal, etc., the hair will gradually become coarser, harder and darker in people who use these methods for a long time.

2. Is it effective to remove hair only by once?

810nm diode laser hair removal generally takes 3-5 times to remove hair clean, there are two reasons: first, most of the hair follicles are three groups bundled together, opening in the same pore, a hair in the pore is a hair in it below a group of three hair follicles in the growth of a hair follicle, so a treatment can only destroy a group of hair follicles. Second, hair growth through the anagen, recession, dormancy, 810 diode laser hair removal treatment in the anagen phase is 75% effective, in recession is 25%, dormancy is almost invalid.

3. After hair removal will affect sweating?

The safe 810nm diode laser hair removal does not affect sweating because sweating mainly depends on small sweat glands, and the opening of the small sweat glands is not in the hair follicle, while the 810nm diode laser hair removal scans the hair follicle without harming the sweat glands, so it does not affect the body's metabolism and sweating.

4. Who is not suitable for 810nm diode laser hair removal?

The 810nm diode laser hair removal is applied to the melanin in the hair follicle, and the laser hair removal device may absorb some of the laser energy in the skin; therefore, people with darker skin and relatively lighter hair color are not suitable for the 810nm diode laser hair removal.
