Laser hair removal is based on the principle of selective photothermal dynamics, through reasonable adjustment of laser wavelength energy pulse width, the laser can cross the skin surface to reach the root of the hair follicle, the light energy is absorbed and converted into heat energy to destroy the hair follicle tissue, so that the hair loses its ability to regenerate without damaging the surrounding tissues, the pain is slight technology, laser hair removal is a safe, fast and long-term hair removal technology.
Limitations
Laser hair removal is not perfect, because it is most suitable for people with light skin tone and dark hair, the treatment area is locked in the “dark pigment”, if your skin tone is dark, the laser will destroy the skin pigment together and cause white or dark spots, after which it often takes several months to gradually recover. Before laser hair removal, you should choose a doctor who has rich experience in laser operation; after the operation, you should take good care and protect yourself from the sun.
Steps to perform
1, skin preparation, the term called skin preparation, in common parlance called shaving, that is, the use of disposable hair removal knife to scrape all the sweat hair on the surface of both arms, so that when the hair removal is carried out, light waves can be the root of the hair “uprooted”. Before preparing the skin, please keep the hair removal area clean to ensure the effect.
2.Gel, apply the gel with cooling effect to the hair removal area, so as to achieve the maximum protection for the skin and minimize the discomfort during the hair removal process. The inside of the arm, although no sweat hair can also be evenly coated with the right amount of gel, to be hair removal together with the acceptance of light waves “intimate contact”, to achieve the role of skin tightening;.
3, laser hair removal, the strength evenly in the hair removal repeated contact, so that the light waves on the root of sweat hair for a thorough “siege”. When the intensity of the light strengthens, the skin will feel more and more intense. According to plastic surgery experts, the use of different light waves, each hair removal area and pain are different ice point hair removal area is relatively large, no pain; photon hair removal area and ice point hair removal the same, will slightly feel the pain, tolerable; and laser hair removal area is very small, the pain is more obvious;.
4, clean, gently scrape off the gel and wash with water, then after cleaning, quickly hydrate the skin and apply sunscreen. In one week after hair removal, do not use soap and other alkaline toiletries to take a bath.
Hair impact
1, the hair is divided into three periods, respectively, the anagen phase, regression phase, stationary phase, the laser instrument can only destroy the hair follicles in the anagen phase, the regression phase, the stationary phase of the hair has no obvious effect, only after these hairs into the anagen phase laser can play a role, so laser hair removal requires multiple treatments, the effect can be obvious;.
2, such as a part of the hair in the growth period of the proportion of small, then the number of treatment to increase. Conversely, the number of treatments can be reduced.
3, based on different parts of the hair has a different growth cycle, each treatment interval also has differences. Such as head hair has a relatively short resting period, so the interval can be as short as l months; trunk and limbs hair resting period is relatively long, so the treatment interval to about 2 months is appropriate so that you can easily enjoy the confidence brought by silky skin;.
4, such as a part of the hair follicle density is too high, then the treatment should be appropriate to reduce the laser energy.
Applicable objects
Laser hair removal is suitable for all parts of dark and light colored hair but not for white hair, all parts of the body (upper and lower limbs, large and small legs, chest, abdomen, hairline, facial beard, outside the bikini line) excess black hair. Those whose hair removal by electric needle, medicine, electric tweezer or other instruments is ineffective or failed.
Post-operative precautions
1.After phototherapy or sun exposure, the skin is damaged by stimulation, which may cause pain, dryness, flaking, and allergies, and then cause side effects such as pigmentation and scars, and even cause excessive relative illumination of light energy during secondary phototherapy care, increasing the risk of returning to black. So the need for professional phototherapy post-operative repair products.
2.Please avoid sun exposure within six months after laser hair removal, and use the sunscreen lotion instructed by the doctor on the affected area to reduce sun exposure.
3.After hair removal, hair removal area may produce slight redness, skin sensitivity and hot or itchy feeling, if you feel pain, use ice to reduce the pain.
4.Be careful not to scald the hair removal area with hot water or scrub hard.
Myths
1, laser hair removal is safe
Laser hair removal is a very safe hair removal method: targeted, no side effects on the human body, almost no effect on the skin.
2, do laser hair removal precautions
Do laser hair removal should pay attention to, hair removal parts in the week before treatment and two weeks after treatment sun protection, hair removal parts should not be done in the two weeks before treatment plucking, waxing and electrolysis hair removal.
3.Laser hair removal need times
Laser hair removal generally requires three to six times, mainly because of two factors: first, most of the hair follicles are a group of three bundled together, opening in the same pore, a hair in the pore is a group of three hair follicles below it in a hair follicle hair growth, so a treatment can only destroy a group of hair follicles; second, hair growth to go through the anagen phase, regression phase, resting phase, in the anagen phase of hair to do laser hair removal for 75% effective, the regressive phase is
25%, resting period is almost invalid.
4.Whether laser hair removal affects sweating
Laser hair removal laser only acts on the melanin in the hair follicle, and there is no melanin in the sweat gland so it will not absorb the laser ability and damage the sweat gland, and there is no other adverse effect on the human body. So laser hair removal will not affect sweating.
5.Whether laser hair removal is harmful to the skin
The human skin is a relatively light-transmitting structure, plastic beauty experts clinical experiments found that in front of the powerful laser, the skin is simply a transparent cellophane, so the laser can very smoothly through the skin deep to the hair follicle, because the hair follicle has a lot of melanin, so it can preferentially absorb a lot of laser energy and eventually converted into heat energy, so that the hair follicle temperature rises, to achieve the purpose of destroying the function of the hair follicle. In this process, because the skin relatively does not absorb laser energy, or absorbs a very small amount of laser energy, so the skin itself will not have any damage.
6.Whether the effect of laser hair removal is permanent
For the effect of laser hair removal is able to permanently remove the hair, of course, in the hair growth period treatment effect is the best, the more melanin secretion, the better the effect of treatment. Laser hair removal is not very useful for hair in the regressive and resting phase, but laser hair removal can inhibit the rapid growth of hair in the short term to achieve the intended effect.
7.Will laser hair removal make the pores bigger
The pores will not become bigger and coarser after photorespiration, on the contrary, the skin will become smoother and more delicate after hair removal.
The reason why the pores will not become thicker after photorespiration is that the light of photorespiration can effectively pass through the skin to reach the location where the hair follicles are located, and can be fully absorbed by the hair follicle tissue and destroy the hair follicles, so that the hair follicles are in a shrunken state, making the pores naturally thinner and smaller. Therefore, after the photo hair removal treatment, instead of making the pores thicker and larger, the pores will be thinner and smaller, and the skin will be fine and smooth.
