Laser hair removal is the least painful of all hair removal methods and is the safest, fastest and longest lasting hair removal technique.
Laser hair removal is based on the principle of selective photothermodynamics. By adjusting the wavelength, energy and pulse width of the laser, the laser penetrates the surface of the skin and reaches the root of the hair follicle, where the light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thus causing the hair to lose its ability to regenerate without damaging the surrounding tissue and causing minimal pain. In addition, laser hair removal uses the "selective photothermal effect" of the laser, which is mediated to a specific wavelength of laser light that passes through the epidermis and directly irradiates the hair follicle. The melanin in the hair follicle and hair shaft selectively absorbs the light energy and the resulting thermal effect causes necrosis of the hair follicle and the hair will no longer grow. The effect of laser hair removal is that the process of heat absorption and necrosis of the hair follicle is irreversible, therefore, laser hair removal can achieve permanent hair removal.
1、The results of many clinical trials show that most patients only feel the sensation of "being bounced by a rubber band".
2, laser hair removal is the advantage of hair removal is very thorough, the use of laser can penetrate to the deep dermis and subcutaneous fat tissue, the role of different parts of the depth of the hair follicle, to effectively remove any part of the human body depth of hair.
The advantage of laser hair removal is that it does not harm the epidermis, does not harm the skin, and does not affect the sweating function, and can effectively protect the skin from damage due to heat. 
4, the advantage of laser hair removal is that the pigmentation after hair removal is relatively very close to our skin.
5. The advantage of laser hair removal is that it is fast.
Side effects of laser hair removal are rare, the most common are the formation of blisters, hyperpigmentation and hypopigmentation, scarring is rare.
① The dose of treatment should be appropriate, usually starting with a low energy test and gradually increasing it up to the point where the patient has a mild burning sensation after treatment and small edematous wind clusters around some of the hair follicles after a few minutes at the treatment site. Avoid rapid whitening of the skin, blistering and epidermal peeling.
It is important to use continuous cooling measures during the treatment and to keep the laser handpiece clean from contact with the skin.
③Prevent infection of the wound surface and take oral antibiotics if necessary.
Duration of treatment
Hair growth occurs during the anagen, regression and resting phases. The laser is effective on the resting hair follicles when they are transformed into anagen hair follicles, so laser hair removal requires three to five treatments to complete the course of treatment. -45 days.
Laser hair removal is currently the safest form of permanent hair removal and is highly targeted, with no side effects on the body and no impact on the skin. Laser hair removal penetrates the surface of the skin and irradiates the areas of the skin where the hair follicles live, leaving very little irradiation on the surface of the skin and no traces on the epidermis after the treatment.
1, laser hair removal price by the hair how much influence, if the hair is more vigorous, body hair more then need more times of treatment, so more times, the price naturally increased.
2, the price of laser hair removal will be affected by the hair removal parts, different parts will have different hair removal difficulty, so the price will also increase.
3, the price of laser hair removal will be affected by the hospital and the doctor, the hospital in hair removal certainly has its own doctors, have their own some charges, so will also have an impact on the price.
The first thing to understand is how the principle of laser hair removal works, laser hair removal controlled pulses of light of the right energy are drawn by the hair follicle tissue to precisely destroy the two important components of the hair follicle, namely the hair bump and the hair papilla. The application of broad spectrum technology provides a gentle, non-invasive treatment that emits special wavelengths of intense pulsed light that penetrates the skin to reach the deepest part of the hair follicle, thereby causing the temperature of the hair follicle to rise rapidly until it is coagulated and necrotic, to maintain the effect of permanent hair removal.
Is the effect of laser hair removal permanent? Laser hair removal technology has been certified to permanently remove hair in the anagen phase after several treatments, the exact number of treatments depends on many factors such as the type of skin and hair. Laser hair removal generally requires three to five sessions, or more in some cases, because there are three phases of the hair growth cycle: anagen, regression and diapause, and only hair in the anagen phase can be effectively removed. The hair in all three growth cycles exists at the same time, so several treatments are necessary to achieve a more complete hair removal.
1. The best wavelength is used for treatment: the laser is fully selectively absorbed by melanin, while the laser can effectively penetrate the skin to reach the location of the hair follicles. The laser's action is effectively reflected in the melanin in the hair follicle to produce heat for hair removal.
2, the best hair removal effect, the required laser pulse time and the size of the hair, the thicker the hair requires a long laser action time, in order to get the ideal effect at the same time can not damage the skin.
3, laser hair removal treatment hair will not be like the traditional hair removal methods after hair removal in the skin surface pigmentation, this is due to the laser hair removal treatment, the skin absorption of laser less.
4. The use of cooling system effectively protects the skin from laser burns during the whole process.
① The area to be removed should be cleaned and disinfected before the laser hair removal procedure and cleaned and bathed;
② Apply a cold pack of ice wrapped in a towel to the area before laser hair removal to reduce pain;
③ Do not use hair removal creams, creams or cosmetics before laser hair removal;
④ Laser hair removal has different efficacy for different individuals and different areas. Factors affecting the individual are endocrine dysfunction, different anatomical areas, skin colour, hair colour, hair consistency, hair growth cycle and depth of the hair follicle. Generally speaking, people with white skin and dark hair have better results.
⑤ The remaining hairs after laser hair removal will become finer and lighter in colour, not darker or coarser.
