Laser Hair Removal Painless Hair Removal

Laser hair removal is selective based on the principle of light and heat dynamics, through reasonable regulation of the laser wavelength, energy, pulse width, laser through the skin surface will be able to arrive at the root of hair follicles, light can be absorbed and converted into the thermal destruction of hair follicles organizations so that the loss of regenerative capacity of hair without damage surrounding tissue, minor pain, laser hair removal is the most safe, efficient, long-term technology to hair. Hair follicle growth cycle as a result of inconsistencies in any part of the hair long-haired ability to have some potential, that is, the incubation period, meaning that the laser phase of the hair follicle regeneration in an effective, while the dormant hair follicles and thus hair growth in accordance with the characteristics of different parts, the general result 2-4 times of treatment, will be able to remove all parts of the body of excess hair.

We all know that the Chinese people's hair is black, this is because hair contains melanin granules. Melanin granules, which is the laser treatment of the target tissue.

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 hair to the surrounding heat conduction, the hair follicles and 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. 800 nm, 100 ms of laser hair removal machine, has a very advanced features.

800纳米波long: fully absorbed by hair follicles, and the complete destruction of hair ball and stem cells, can be permanent hair removal; 100 ms long pulse width: treatment time of 100 ms pulse to enhance the safety of treatment for different thickness of hair and patients with different skin colors.

Contact with the first laser cooling: sapphire window close to the treatment of 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 on the laser absorption increased by 30% -40%.

9mm square big spot to make a big spot beam to penetrate deeper and improve the curative effect. The elimination of a circular spot can be a square light spot treatment between "dead zone."

Laser Hair Removal Methods:

1. Preoperative preparation:剃除body hair in order to avoid skin burns treatment. Generally do not need anesthesia.

2. Treatment: the first contact with the laser treatment area, post-irradiation soft reduction, the moment of regional treatable area of 9mm2. Part of the initial treatment may have a small amount of hair regeneration, but will be less obvious than before and thin, can be treated again. 3-5 times in general will be satisfied by the results.

3. Effect: the treatment of thousands of people abroad that the practice of safe and effective laser hair removal. Christin.C.Dierickx Harvard University, 92 medical patients, long-term hair removal rate was as high as 89%.

Laser hair removal side effects

First, surgery

1. Pain: for each laser irradiation, there may only be slight, transient skin pain, stop the exposure that is disappearing without anesthesia;

2. Erythema: after laser irradiation region in the temporary skin redness;

3. Mission style: laser irradiation, in the pores there is "" a small swollen package "," after the mosquito bites as a small pimple, 1-2 hours after spontaneous regression;

Second, after the operation

1. Erythematosus: light irradiation region can be red, a few days after the general spontaneous regression;

2. Dehulling: some people after treatment of local skin callus thin brown skin, about 1 week off naturally;

3. Pigmentation: a small number of people that may arise after the treatment of light brown spots on skin This is a response to laser treatment, because only a small number of people took place, which the special physical and individuals concerned. If pigmented, most of them can resume in a few months. 800 nm, 100 ms of the semiconductor laser, than the average 30 ms longer laser pulse width, and equipped with a cooling head, and thus the possibility of occurrence of pigmentation smaller.

4. Scar: In theory this will not lead to selective laser hair follicle of the surrounding normal tissue damage is not reversible. However, if special physical, or neglect after partial cleaning, bacterial infection, it may be a small scar.

Wuxi Tongji Hospital medical cosmetic beauty experts advise: Laser in the application with non-bleeding, tissue reaction to light, in patients with less pain and rapid recovery. While speaking with laser treatment is simple, but the need for experienced physicians to operate under the plastic is safe and reliable, the choice of indications to be determined by the doctor, otherwise difficult to achieve the best results.
