The principle of laser hair removal, the advantages and indications

Laser is a special kind of light, when the laser irradiation on the human tissue, the organization can be absorbed by human hair follicle matrix cells, hair follicle epithelium, dermal papilla, hair contain melanin, melanin absorption of light energy, and when the hair follicles absorb the light energy after Local produce heat, hair follicle cells, necrosis, hair follicle atrophy, and to achieve the purpose of permanent hair removal.
The principle of laser hair removal:
Laser hair removal is selective based on the principle of light and heat dynamics, 800纳米波long laser through the skin into the dermis, the selectivity of hair and hair follicles were in the absorption of melanin granules, resulting in photo-thermal effect of the thermal hair conduction to the surrounding, and the hair follicle stem cells, such as "hairy root" completely destroyed, resulting in permanent hair removal. Normal tissue surrounding the hair follicle melanocytes by free particles, so there is no absorption of this laser is affected is very small, usually does not cause scarring.
The five major advantages of laser hair removal
1, the best of the laser wavelength
LightSheer semiconductor laser wavelength is 800 nm in the near-infrared spectral region, melanin absorption is better, at the same time to penetrate to the deep dermis and subcutaneous adipose tissue, the role and depth in different parts of hair follicles, effectively removing any part of the human body and depth of the hair.
2, long time adjustment optical pulse to protect the skin while removing hair of different thickness
The effect of the best hair removal laser pulses required for the time and the thickness of the hair, coarse hair more time required for the longer laser, LightSheer semiconductor laser pulse of laser light red cent from 5 seconds to 100 milliseconds, to obtain the desired hair removal effect while at the same time effectively protect epidermis from thermal damage.
3, the most suitable pigmentation Asia
The traditional laser hair removal, hair removal arising in skin pigmentation, skin inflammation occur. And laser hair removal as a result of deeper penetration depth Lightsheer, skin absorption of laser energy very few, so no melanosis there is no inflammation.
4, patented technology security does not damage the skin
Exposure to laser cooling in the treatment of sapphire window close to the skin, so that local skin cooling to 5 degrees, not only effectively protect the normal skin from heat damage, reduce pain, the treatment can increase energy, enhance the effectiveness of treatment. At the same time, the first under the pressure of laser skin, hair follicles so that lodging, so that the absorption of laser an increase of 30% -40%.
5, square spot, rapid removal of hair, to speed up treatment of the speed of
Laser hair removal is designed to spot 9 mm square spot, carry out a large area of skin hair removal not only efficient, fast, and can eliminate the traditional circular spot formed by laser treatment overlap.
Laser Hair Removal indication:
Various parts of the body (upper limbs, and large legs, chest, abdomen, hair, facial beards, bikini line) hair black redundant. Electro-acupuncture, drugs, electric hair removal tweezers apparatus invalid or losers.
