Do You Know Everything About Laser Hair Removal

Nov. 18, 2020


Before the popularization of Laser Hair Removal, electrolytic hair removal and thermal dissolution hair removal have appeared, which can achieve the effect of permanent hair removal. However, because the treatment methods are backward and have been eliminated, laser hair removal methods are mainly used in clinical practice.


The principle of laser hair removal is to take advantage of the different absorption rates of different materials for different wavelengths. With a suitable wavelength range, the laser can penetrate to the depth of the hair follicle. The laser has extremely high energy and can be selectively The melanin in the hair follicle is absorbed. After the melanin absorbs the energy of the laser, the temperature rises sharply, which leads to the destruction of the surrounding hair follicle tissue, and the hair loses its ability to regenerate.


Is laser hair removal safe?


As long as it is treated in a regular medical institution, it is very safe. In the process of using the Laser Hair Removal Machine, the hair follicle melanin absorbs most of the heat, so the energy diffused to the surrounding skin is relatively low, and the skin surface will not be significantly different after the operation, and there is no need to stop work or ask for leave. Of course, laser hair removal still has some minor side effects:


1. During the laser hair removal process, the skin will have a slight tingling sensation, and there may be a slight burning sensation after the operation, and mild erythema or follicular papules on the local skin will generally subside within a few hours. After laser hair removal, a small number of people have brown thin crusts on the local skin, which will fall off naturally in about 1 week.


2. A very small number of patients will develop purpura, blisters, temporary hyperpigmentation or hypopigmentation, most of which can recover within a few months.


3. It should be noted that because the pain may stimulate contractions, although the pain is not strong, it is still not recommended to perform laser hair removal during pregnancy


4. Scars caused by laser hair removal are rare, but patients with a history of keloids should still be cautious.


Most of these side effects are mild, and you can recover quickly if you take appropriate care measures after the operation. Don't worry too much.

How many times do you need to do laser hair removal? Will it rebound?


In order to achieve a good hair removal effect, generally 4-6 laser treatments are required. A single laser treatment is only more effective for hairs in the growth phase, while the hair follicles in the resting and degenerative phases have less melanin content. Laser treatment can only be effective when these hairs enter the growth phase. Therefore, laser treatment requires multiple treatments to achieve the desired effect. The interval between each treatment needs to be determined based on the specific situation of each person after treatment. Generally, 1-2 months are appropriate.


In clinical practice, some people will still grow new hair after 6 laser treatments. At this time, it is necessary to decide whether to continue treatment according to the state of the newly grown hair. If the new hair is as thick as before and the color is darker, then it needs to continue treatment. After all, everyone has a different body constitution, and some people's hair is relatively "stubborn".


If these new-born hairs are like villi and are very light in color and are not easy to find without careful observation, no further treatment is needed, because such hairs have a low melanin content and a poor response to the laser. It is of little significance to continue treatment and there is no need to worry about the future. The problem of increased and thickening of rebound hair will occur.


Does laser hair removal affect perspiration?


The Laser Hair Removal Equipment Supplier definitely tells us that it will not affect! Human perspiration mainly relies on eccrine glands, and laser hair removal is to sweep hair follicles, hair follicles and sweat glands are two independent tissues. Hair grows from the hair follicle, while the sweat glands are next to the hair follicle. The two are not the same thing. Therefore, laser hair removal will not damage sweat glands and affect perspiration.


What are the precautions after laser hair removal?


After laser treatment, we need to do the corresponding nursing work to achieve the best results. After laser treatment, the local skin is more sensitive and the pores are easy to open. It is recommended to avoid swimming and bathing with too high water temperature within 24 hours to reduce irritation and avoid infection. Keep local skin clean, it is recommended to wear pure cotton clothing.


It is recommended that skin care products such as body lotion and moisturizer should not be used within 24 hours. These products may irritate the local skin. If necessary, use medical skin care products for care. You should pay attention to sun protection within 2 weeks of treatment to avoid local skin pigmentation caused by sunlight. Although it will eventually subside, it will take a longer time. Sunbathing, sweating and steaming are strictly prohibited. It is recommended to eat less spicy and irritating foods and more fruits and vegetables rich in vitamin C. Vitamin C can improve skin resistance, reduce pigmentation, and achieve whitening and spot-lightening effects.
