Knowledge points about laser hair removal

1. Will sweating be affected after laser hair removal?

Since sweat glands and hair follicles are two independent tissues, and the wavelengths of the two absorb laser light are different, laser hair removal will not affect sweating.

According to the theory of selective photothermal action, as long as the appropriate wavelength, pulse width and energy density are selected, the laser can precisely destroy the hair follicle without causing damage to the adjacent tissue. The study showed that the histological structure of the sweat glands was not damaged after laser hair removal, and the sweat gland function of the patients was basically unaffected by clinical observation. Using advanced laser hair removal equipment, not only will not damage the skin, but also shrink pores, making the skin smoother and more delicate.

2.Will laser hair removal affect other normal skin?

Laser hair removal is a very safe and effective method of hair removal. It is highly targeted and has no side effects on the human body. The skin of the human body is a relatively light-transmitting structure. In front of a powerful laser, the skin is simply a transparent cellophane, so the laser can penetrate the skin and reach the hair follicle very smoothly. Because the hair follicle has a lot of melanin, it can be absorbed preferentially. A large amount of laser energy is finally converted into heat energy, which increases the temperature of the hair follicle and achieves the purpose of destroying the function of the hair follicle. In this process, since the skin does not absorb laser energy relatively, or absorbs a very small amount of laser energy, the skin itself will not have any damage.

3.Is laser hair removal painful?

Mild pain, but the level of pain varies from person to person. The degree of pain is mainly judged according to the skin color of the individual and the hardness and thickness of the hair. Generally, the darker the skin color, the thicker the hair, and the stronger the stabbing pain, but it is still within the tolerable range; the skin color is white and the hair is thinner. ! If you are sensitive to pain, you need to apply anesthesia before treatment, please communicate with the therapist first.

4.Is laser hair removal permanent?

Yes, three decades of clinical proof, laser hair removal is the only effective permanent hair removal. The laser penetrates the surface of the skin andreaches the hair follicle at the root of the hair, directly destroying the hair follicle, thereby making the hair lose its ability to regenerate. Since the process of endothermic necrosis of hair follicles is irreversible, laser hair removal can achieve permanent hair removal. Laser hair removal is currently the safest, fastest and most durable hair removal technology.

5.When is laser hair removal?

It depends on the area to be treated. The hair removal time is about 2 minutes for lip hair, about 5 minutes for armpit hair, about 20 minutes for calves, and about 15 minutes for arms.

6.How many times does laser hair removal take?

There are three periods of hair growth: the growth phase, the regression phase and the stationary phase. Only when the hair follicle is in the growth phase will there be a large number of pigment particles in the hair follicle, and a large amount of laser energy can be absorbed, so laser hair removal treatment cannot be successful at one time, usually It takes several consecutive laser exposures to achieve the desired effect of permanent hair removal. Generally, after 3-6 treatments, the hair will not grow back, of course, very few people need more than 7 treatments.

7.Are there any side effects of laser hair removal?

Laser hair removal is a relatively advanced permanent hair removal method, and no side effects have been found so far.
