Laser depilation is a popular way of depilation, but what harm does laser depilation do? This problem is also worried by many people. A lot of hair is very troublesome for girls. Of course, now that beauty technology is so developed, many people choose laser hair removal, but will laser hair removal be harmful?
Laser hair removal principle: laser hair removal uses the selective photothermal principle to produce hair removal effect. By reasonably adjusting the laser wavelength energy, the laser with specific wavelength can be fully absorbed by the melanin in the hair follicle and generate heat, so as to destroy the normal growth function of hair. Because the process of heat absorption and necrosis of hair follicles is irreversible, the depilation effect is permanent.
Laser hair removal may cause slight redness or local edema at the treatment site, but such reaction usually disappears within 12 to 24 hours. The most common hazards of laser hair removal are blister formation, pigmentation and hypopigmentation, and the pigment changes are usually temporary. Scabs are occasionally seen, and scars are rare. However, after laser hair removal, you can also have smooth and delicate skin.
However, laser hair removal varies from person to person, and the following situations may occur:
1。 Erythema reaction: temporary redness of skin in the laser irradiated area during laser hair removal;
2。 Wind mass reaction: after laser irradiation, there is a small swelling in the pores, like a small pimple after mosquito bite. It can subside naturally 1-2 hours after laser depilation operation;
3。 Pain reaction: every time the laser irradiates, there may be slight and instantaneous skin pain, which will disappear after stopping the irradiation without anesthesia.
These reactions of laser hair removal can generally disappear by themselves. If you want to avoid these situations of laser hair removal, you must go to a regular hospital, so as to ensure the safety of treatment and avoid unnecessary damage.
