When using a laser hair removal device, it is generally necessary to clean the local skin surface first, and then directly use the laser hair removal device to irradiate the local skin. It mainly penetrates into the deep layer of the skin through the principle of photothermodynamics, which can shrink the hair follicles in the skin and make the hair follicles lose the activity of growing hair, so as to achieve a certain effect of hair removal. However, it takes several treatments to completely remove the hair in the deep layer of the skin and make the skin smoother.
The correct use of laser hair removal equipment includes preparation before hair removal, laser hair removal, and post-hair removal care. The laser hair removal device uses the photothermal effect to let the laser light penetrate to reach the root of the hair follicle, and generate instantaneous high temperature to destroy the hair follicle, so that it will no longer grow hair for a period of time.
- Preparation before hair removal
Skin preparation and gel application are required before epilation. Skin preparation is to shave off the hair from the depilated area. You can use a razor to gently shave the hair on the corresponding part, usually 2-3 days before depilation. Before using the laser hair removal device, you need to apply a layer of gel evenly on the hair removal site to ensure complete coverage.
- Laser hair removal
After applying the gel, you can use a laser hair removal device for hair removal. When removing hair, put the instrument close to the hair, and then move it back and forth gently and repeatedly, usually 3-5 times back and forth. There may be slight pain during this process, and the hair removal area may feel warm.
- Care after hair removal
To care for the skin after hair removal, you can apply moisturizer to the hair removal site to replenish moisture.
Usually, pay attention to sun protection, apply sunscreen and wear sunscreen clothing when going out. At the same time, pay attention to avoid scalding the hair removal area with hot water, or applying cosmetics, so as not to irritate the skin and affect skin repair.
People with hair on their body can not only use laser hair removal equipment to remove it, but also use freezing point laser to remove it, which is also a permanent hair removal method. Laser is a kind of physical therapy method, which can act on the hair follicles to penetrate deep into the skin tissue through the photothermal effect. After stimulating the hair follicles, it can inhibit the growth of local hair without causing damage to the surrounding skin tissue. Everyone's hair growth cycle is different. Generally, laser hair removal is performed several times. Under normal circumstances, laser hair removal requires an interval of about 4 to 8 weeks between each course of treatment. The next laser hair removal treatment can only be done after new hair grows out. For example, after calf hair removal, it needs to be corrected for about 20 days. Different individuals and different parts will affect the number and interval of laser hair removal treatments. Because the hair growth cycle has three phases, only the hairs in the growth phase can be effectively removed. Generally, it takes 3-5 treatments to achieve permanent hair loss. Even if a small amount grows back, it will be thinner and shorter than before. The intense pulsed light emitted by the laser hair removal device acts on the roots of the hair follicles to achieve the purpose of hair removal. Impairs the activity in the hair follicle, so hair cannot grow back. The laser only absorbs the corresponding pigment cells and does not damage the surrounding normal skin. It is a safe and fast treatment method.
