Are there any side effects of laser hair removal? The truth is this

Now there is a method of laser hair removal. Many people want to solve their long-standing problems through this method, but they are worried that this method is not safe and that it will leave sequelae, etc. Let's take a look at the authoritative answers below.

1. Is it safe?

Laser hair removal is a very safe hair removal method: it is highly targeted, has no side effects on the human body, and has almost no effect on the skin.

2. Whether the frequency is required

Laser hair removal generally requires three to six treatments, mainly due to two factors: first, most hair follicles are bundled together in groups of three and open into the same pore. A hair in a pore grows from one of the three follicles in the group below it, so one treatment can only destroy one follicle in a group; second, hair growth goes through the growth phase, regression phase, and resting phase. Laser hair removal is 75% effective in the growth phase, 25% in the regression phase, and almost ineffective in the resting phase.

3. Does it affect perspiration?

The laser used in laser hair removal only acts on the melanin in the hair follicles. There is no melanin in the sweat glands, so it will not absorb the laser energy or damage the sweat glands, and it has no other adverse effects on the human body. Therefore, laser hair removal will not affect sweating.

4. Is there any harm to the skin?

The human skin is a relatively transparent structure. Plastic surgery experts have found in clinical experiments that in the face of powerful lasers, the skin is simply a piece of transparent cellophane. Therefore, the laser can penetrate the skin very smoothly and reach the hair follicles. Since the hair follicles contain a lot of melanin, they can preferentially absorb a large amount of laser energy and eventually convert it into heat energy, which increases the temperature of the hair follicles and achieves the purpose of destroying the function of the hair follicles. During this process, since the skin relatively does not absorb laser energy, or absorbs very little laser energy, the skin itself will not be damaged.

6. Is the effect permanent?

As for the effect of laser hair removal, it can remove hair permanently. Of course, the treatment effect is best during the hair growth period. The more melanin is secreted, the better the treatment effect. Laser hair removal is not very effective for hair in the regression and resting phases, but it can inhibit the rapid growth of hair in the short term and achieve the desired effect.
