Is laser hair removal safe?


Laser hair removal can easily get rid of the trouble of hairiness. It is the first choice for many beauty lovers. But is laser hair removal safe? Is there any adverse effect on the skin? Will the body hair grow again after finishing? This is a problem that many people are concerned about.

Today, we invited Zhou Cheng, deputy chief physician of Dermatology Department of Peking University People’s Hospital, to answer your questions.

Zhou Cheng:

Girls with thick body hair often ridicule themselves as “peaches”. In order to become “nectarines”, they use all kinds of “weapons” to deal with body hair: for example, shaving knives are economical and convenient, and the effect is immediate, but the effect can only last for 3 ~ 5 days, and the hair will tend to be thicker and thicker, which is easy to damage the skin barrier, resulting in skin sensitivity, redness and even inflammation; Depilatory cream, most of which contain chemical ingredients, has great irritation to the skin and is easy to be allergic, and the effect will not last long; Depilation beeswax, the depilation process is quite painful, and it is easy to cause folliculitis. The effect can last for about 2 weeks at most.

The above methods are short-term hair removal, which can only remove body hair and has no effect on hair follicles, so it will soon be “endless wildfire and spring breeze”. At present, the only way to completely destroy hair follicles and achieve long-term hair removal effect is laser hair removal.

According to the theory of selective photothermal action, laser hair removal works against the melanin of hair stem and hair follicle by reasonably adjusting the laser wavelength, energy and pulse width. The light energy is absorbed by melanin and converted into heat energy, which can target and destroy the hair follicle tissue, so as to lose the regeneration energy of hair and achieve the purpose of permanent hair removal without damaging the surrounding tissue, High safety and mild pain.
