Firstly : Equipment,Skin type,hair removal knowledge

1、The origin of Diode laser hair removal ： at 1993 ， The Wellman Medical Optics Laboratory at Harvard University begins research into ruby laser hair removal，at 1997，The birth of photon also has a certain effect in clinical hair removal, but because the photon penetration is shallow, the treatment times are more, the hair removal ability is limited.. Finally ，Israel's high-tech city CAESAREE Research Center began
using a new generation of laser hair removal machine——MYTHOS 500 Alma diode(Semiconductor) laser hair removal equipment for clinical treatment，has achieved a clear effect, and then there are a variety of professional hair removal laser equipment such as: long pulse 1064nm, Alexandrite 755nm, etc. have emerged, so that the effect of laser hair removal into a perfect era.

2、The Principle ：（Semiconductor） Diode laser hair removal is a non-invasive modern hair removal technology, which can destroy hair follicle structure and permanently remove hair without scalding the skin.

3、Skin Types ：According to Fitzpatrick classification, the skin color was divided into 6 types: white skin in Europe and America were I, II; Southeast Asian yellow skin type III, IV; African brown black skin type V, VI. Type I II skin has less melanin in the basal layer. It is safe to use 810 nm diode laser or 755 nm laser. The content of melanin in the basal layer of V-VI type brown and black skin is very high and 1064 nm laser is more suitable. Type III-IV yellow skin race, skin basal layer melanin content is medium,810 nm Diode laser is the safest.

The growth of hair goes through three stages: growth phase,recession phase and telogen phase. There is melanin in the hair follicle in the growth phase, less in the retrogressive phase, and no melanin is in the telogen phase. The laser mainly damages the growth follicle. Skin telogen follicles will continue to change into growing hair follicles, so the necessary treatment of laser hair removal 3 to 5 times can be completely hair. Discontinuous 30days.

3）、Whendepilating under the specially adjusted parameter mode, it can form a large area physiological heat effect on the melanin basal cells of the skin, thus inhibiting melanin production of basal cells for a long time, and achieving skin whitening.

810nm ：（1）、810nm Diode laser ，Has good uniformity, has better penetration, It is also a relatively good wavelength for melanocytes, which is applied to the principle of selective photothermal effect. The melanin of hair follicle is the target color base, which effectively destroys hair follicles and achieves a better hair removal effect. (2) In the case of patients with darker skin, the target tissue and the epidermis have the same color base and compete with each other to absorb the laser, so there may be a risk of epidermal retention heat for dark skin; However, better curative effect can be obtained for patients with lighter skin color.

1064nm wavelength features: It has the advantages of deep penetration, long pulse width, large energy density range, etc. It is suitable for hair removal of various skin types (especially type IV ~VI skin) and color hair except white.
