The so-called laser hair removal is a medical hair removal method. It is by far the safest, fastest and permanent hair removal method. It is based on the principle of selective photothermal dynamics. By reasonably adjusting the laser wavelength and energy pulse width, the laser can pass through the surface of the skin to the root hair follicle of the hair. The light energy is absorbed and transformed into heat energy that destroys the hair follicle tissue, so as to make the hair lose the regeneration ability without damaging the surrounding tissue and slight pain. It’s just about laser hair removal. Many beauty seekers don’t understand it. Let’s take a look at the following three common questions.
Question 1: does laser hair removal hurt?
Laser hair removal is a little tingling, because local hair follicles of the body will have sensory nerves. If the hair follicles receive enough laser energy, the body will feel a certain degree of pain. If it doesn’t hurt at all, the energy of the laser is not enough and needs to be readjusted.
Question 2: is laser hair removal permanent hair removal?
To carry out a complete course of laser hair removal, generally speaking, a course of hair removal needs about three or five times, which can be completed in about three or four months. From then on, you will no longer worry about excess hair.
Question 3: what is the principle of laser hair removal?
According to experts, the principle of laser hair removal is based on selective photolysis. Due to the rich melanin in hair follicles and hair stems, melanin is distributed between the cells of hair bulb matrix and transferred to the structure of hair stems. Laser hair removal takes melanin as the target for hair removal treatment. After the target hair follicle and the tissue around the hair follicle absorb the huge energy of the specific wavelength 1064nm laser beam, the temperature rises sharply, resulting in the destruction of the hair follicle and the tissue around the hair follicle, the hair loses its original environment and is removed nearly and permanently.
The above three questions about laser hair removal have been asked by many beauty seekers. I believe that through the introduction of the above small series, we should all know that compared with the hair removal cream and manual shaving methods we often use, laser hair removal is still the most ideal and effective method. However, those seeking beauty must choose formal plastic and cosmetic institutions.
