Laser hair removal is a popular way of hair removal, but few people will do it, because we are too afraid that it will do harm. So what's the disadvantage of laser hair removal? Let's learn about it.

What are the disadvantages of laser hair removal

Laser hair removal is to use the selective photothermal principle to produce hair removal effect. By adjusting the laser wavelength energy reasonably, the specific wavelength laser can be fully absorbed by the melanin in the hair follicle and generate heat, thus damaging the normal growth function of hair. Because the process of heat absorption and necrosis of hair follicles is irreversible, the hair removal effect is permanent.

Generally speaking, laser hair removal will not cause damage to the skin around the hair removal part, but it should be noted that if the relevant nursing measures are not done well before and after the operation, or some people who are not suitable for laser hair removal have been operated on, it will cause harm to the body. After laser hair removal, the skin of the hair removal part will appear temporary redness and swelling, and some may also be accompanied by tenderness. These discomfort phenomena are normal and can be relieved by cold compress, so there is no need to worry.

In addition, laser hair removal may cause skin burns, but it is not a common phenomenon, and these problems are generally seen in people with darker skin color, which is mostly caused by high laser intensity and long hair removal time. In serious cases, it may lead to long blisters on the skin, and even cause scars. Because laser hair removal is to absorb the pigment in hair follicles by laser, it is possible for people with black skin to absorb part of laser energy during treatment, thus causing certain damage to the skin. Therefore, laser hair removal is especially suitable for those with fair skin and dark hair.
