Laser hair removal is based on the principle of selective photothermodynamics. By reasonably adjusting the pulse width of the laser wavelength energy, the laser can pass through the skin surface and reach the hair follicles at the root of the hair. The light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thereby making It is a safe, fast and long-lasting hair removal technology that loses the ability of hair to regenerate without damaging surrounding tissues, with mild pain. Therefore, laser hair removal or photon can achieve long-lasting hair removal.

Features of Laser Hair Removal

1. The best wavelength is used for treatment: the laser can be fully selectively absorbed by melanin, and the laser can effectively penetrate the skin to the location of the hair follicle. The effect of the laser is effectively reflected in the melanin in the hair follicle to generate heat for hair removal.

2. For the best hair removal effect, the required laser pulse time is related to the thickness of the hair. The thicker the hair needs a longer laser action time, and the desired effect can be obtained without damaging the skin.

3. Laser hair removal will not produce pigment deposits on the skin surface after hair removal like traditional hair removal methods. This is because the skin absorbs less laser light during laser hair removal treatment.

4. The use of cooling system can effectively protect the skin from laser burning during the whole process.

Effects of laser hair removal on hair

1. Hair is divided into three periods, namely growth phase, regression phase, and stationary phase. The energy emitted by the laser instrument can only destroy the hair follicles in the growth phase, and has no obvious effect on the hair in the regression phase and stationary phase. The laser can only work after entering the growth period, so laser hair removal requires multiple treatments for the effect to be obvious.

2. If the proportion of hair in a certain part is small, the number of treatments should be increased. Conversely, the number of treatments can be reduced.

3. The hair of different parts has different growth cycles, and the interval between each treatment is also different. For example, the hair on the head has a relatively short rest period, so the interval can be as short as one month; the rest period of the trunk and limbs is relatively long, so the treatment interval should be about 2 months, so that you can easily enjoy the silky skin. confidence.

4. If the density of hair follicles in a certain part is too high, the laser energy should be appropriately reduced during treatment.

The effect of laser hair removal

Laser hair removal is a less painful hair removal method among all hair removal methods. Clinical test results: After 3~5 courses of treatment, more than 95% of the cases have 80% hair loss, and the hair becomes less, finer, and more colorful. Shallower and slower growing. All cases demonstrated 30% to 50% hair reduction if only 1-2 sessions were done. In most clinical cases, the average energy density used is only 10~20J/cm2 for efficient hair removal, thereby avoiding possible medical risks such as burns.

Advantage

1. Laser hair removal is one of the less painful hair removal methods among all hair removal methods. Most people just feel "bounced by a rubber band".

2. The advantage of laser hair removal is that the hair removal is very thorough. The laser can penetrate into the deep layer of the dermis and the subcutaneous fat tissue, and act on the deep hair follicles in different parts to effectively remove the deep hair in any part of the human body.

3. The advantage of laser hair removal is that it does not damage the epidermis and is very fast.

4. The laser hair removal light pulse time is adjusted for a long time, which protects the epidermis and removes hairs of different thicknesses.

5. The patented technology of sapphire contact cooling cooling is safe and does not damage the skin, which is the most prominent advantage of laser hair removal.

6. The laser pulse time required for the best hair removal effect is related to the thickness of the hair. The thicker the hair, the longer the laser action time.

7. The sapphire window of the contact cooling laser head is close to the skin during the treatment, so that the local epidermis is cooled to 5 degrees, which not only effectively protects the normal skin from thermal damage and relieves pain, but also increases the treatment energy and improves the curative effect. At the same time, the laser head is pressed down The skin lodging the hair follicle increases the absorption of the laser by 30%-40%.

8. Square large spot to quickly remove hair and speed up treatment

The laser hair removal spot is designed as a 9 mm square spot, which is not only efficient and fast when removing large areas of skin, but also eliminates the treatment overlap area formed by the traditional laser circular spot.
