The principle of laser hair removal, in real life, many friends will dislike their Mao Mao, so these friends are looking for ways to remove hair, and some will use hair removal stickers, hair removal liquid and so on. There are also some friends who want to remove hair for a long time who have tried laser hair removal, so what is the principle of laser hair removal? Let's take a look!

Principle of laser hair removal 1

Laser hair removal principle

Laser hair removal is based on the principle of selective photothermal kinetics. By adjusting the laser wavelength reasonably, the beam will penetrate the skin surface and be absorbed by the hair follicle. By selectively absorbing laser energy, hair follicles are damaged and hair loses its regeneration ability without damaging surrounding tissues. Plastic surgeons adjust a specific wavelength of laser light to pass through the epidermis. Because of the process of hair follicle endothermic necrosis, the effect of laser hair removal is irreversible. So laser hair removal or photon hair removal can achieve the long-term hair removal effect.

Characteristics of laser hair removal

1, and the best wavelength is adopted for treatment: the laser can be selectively and fully absorbed by melanin, and the laser can effectively penetrate the skin to reach the hair follicle position. The effect of laser is effective. Melanin embodied in hair follicles generates heat for hair removal.

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

3. Laser hair removal treatment will not produce pigment precipitation on the skin surface after hair removal like traditional hair removal methods, because the skin absorbs less laser during laser hair removal treatment.

4, the use of cooling system, the whole process effectively protect the skin from laser burns.

Laser hair removal is based on the principle of selective photothermal kinetics. By reasonably adjusting the laser wavelength and energy pulse width, the laser can pass through the skin surface to reach the hair follicle at the root of the hair, and the light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thus making the hair lose its regeneration ability without damaging the surrounding tissues and causing slight pain. Laser hair removal is the safest, fastest and longest-lasting hair removal technology at present. At present, the common laser hair removal methods are semiconductor laser hair removal, photon hair removal (ipl) and emerald laser hair removal.

What should I pay attention to after laser hair removal?

First, pay attention to diet.

Diet after laser hair removal surgery can not be ignored. Never eat spicy food, such as pepper, pepper, ginger, mustard, etc. , so as not to affect the recovery of hair removal parts. You can eat some vitamin C tablets, or eat some vegetables and fruits rich in vitamin C, such as broccoli, Chinese cabbage, lettuce, tomatoes, kiwi fruit and so on.

Second, pay attention to dress.

After laser hair removal surgery, the skin will become very fragile. After hair removal, the skin pores are in a state of expansion, which is easily affected by pigments and easily stimulated. Therefore, don't wear clothes that fade or get dirty easily, otherwise it will cause inflammation of the wound.

Third, pay attention to the use of skin care products.

After laser hair removal surgery, the skin will become sensitive. It is best not to use cleaning products and skin care products in the hair removal area for 3 days, and then choose cleaning products and skin care products that are less irritating to the skin. Be careful not to use scrub.
