What is professional permanent laser hair removal?

The principle of laser hair removal (laser hair removal), the professional saying is: selective photothermal theory.

In other words, hair follicles and hair are rich in melanin. The darker substance (melanin) absorbs light energy and generates more heat, and the temperature rises sharply, which leads to the destruction of the surrounding hair follicle tissue and the hair is removed. It's like basking in the sun in winter, and people who wear black clothes get hotter than those who wear white clothes.

After the hair follicle is destroyed, it can achieve the effect that long-term hair can no longer grow for a long time. This time can be maintained for half a year to 2 years (depending on the hair characteristics of different people). But note that laser hair removal is only "long-lasting hair removal", not "permanent hair removal". Give up, there is no permanent way to get rid of hair in the world.

Professional laser hair removal is safe

In 1995 the United States (US) Food and Drug Administration (FDA) approved the use of lasers in the US as a medical device for hair removal. In 1999, the FDA gave lasers and flash lamp systems clearance for use in "permanent hair reduction".

So laser hair removal is safe, but it can occasionally cause side effects, such as pain and discomfort, and red skin that may last for some time. It may also not be suitable for everyone, including pregnant women and people with certain skin types. There's no evidence to suggest that laser hair removal causes skin cancer.

Everyone should be most concerned about this, after all, it is the instrument that hits the skin. Generally speaking, laser hair removal is safe as long as it is a formal institution and professional.

Laser hair removal uses the principle of melanin heat absorption to emit light of a wavelength suitable for the absorption of melanin in the hair follicle. After melanin selectively absorbs light energy, the local temperature rises sharply, and the hair follicle tissue will be destroyed, and this thermal damage can be limited. It is located in the target tissue, that is, the hair follicle containing melanin, so it will not cause damage to the surrounding tissue.

Foreign surveys show that 90% of women believe that laser hair removal is safe and reliable

However, if the irradiation energy and lighting time are not suitable, it is easy to cause local damage to the skin, so laser hair removal is a test of the professionalism of the personnel, so a professional organization should do a patch test before hair removal: use the machine on the inside of your arm. Irradiate three points with different energy, see the maximum energy you can accept, and then adjust the energy of the machine according to your value.

FAQs about Professional laser hair removal

Does hair removal affect perspiration?

Hair removal will definitely not affect perspiration! The hair follicle selectively absorbs light energy during the treatment, so that the sweat glands will not receive a lot of heat, not to mention that the human body has sweat glands that are independent of the hair follicles, so sweating is not affected.

Will my skin become sensitive after hair removal?

No, we have some misunderstandings for sensitive cases. The process of hair removal is mainly photothermal, which will take away the moisture in the skin, so the skin moisture content will drop after surgery, and the skin may appear red, etc. Reaction, but these can be ignored during body hair removal, mainly after facial hair removal, you need to do a certain amount of hydration and moisturizing so that the skin will not suffer from various complications due to reduced moisture. Also remember, after hair removal, be sure to use sunscreen and avoid direct sunlight!

Will the new hair grow thicker if I shave it with a razor?

This is a false proposition. Because the angle of shaving is inclined, just like cutting a cucumber, the cross-section of the diagonal cut is naturally larger than the cross-cut. And when the hair just grows out, it is hard, so it looks thicker. It's just a matter of visuals, a more razor blade doesn't matter.

When is the best season for hair removal?

In fact, you can do it anytime, but I recommend doing it after the fall. Because hair removal needs at least 6 times to achieve satisfactory results, each hair removal must be separated by 1-1.5 months; and pay attention to sun protection. So if you wait until summer hair removal, then you can't go out for at least 2-3 days. From this point of view, it is best to take off the hair removal season after the fall and before May or June, so that you can spend the summer beautifully~

The price, I heard that it is not clean once, but I don’t know how many times and how much it will cost?

If the hair removal is not clean at one time, there is no technology that can achieve permanent hair removal at one time. Generally, it takes about 4-6 times. Depending on the individual hair situation, not everyone has the same number of times.

As for the price, the price of different parts is also different. For example, the price of the armpit and bikini is definitely different. The subject wants to consult the whole body laser hair removal, and the price should be psychologically prepared, but it is best to try a small part before deciding to take off the whole body!

I usually shave my hair, so I don't know if it has any effect on laser hair removal.

Do not treat the hair by yourself before hair removal, it is convenient for the therapist to check the hair condition, and it also prevents the pores from expanding or even folliculitis due to the wrong method. In short, if you decide to laser treatment, stop treating the hair yourself!

The place where hair removal should choose a regular hospital is the best? Can a beauty salon do it?

Objectively speaking, if the price of the hospital is the same as that of the beauty salon, no one will worry about where to go for hair removal. It is professional and at ease. The disadvantage is that the cost performance and the doctor may not be able to specify.

In addition to beauty salons, there is also a store like ours that wants to do hair removal exclusively for hospitals. Compared with beauty salons, it wants to be specialized in professional hair removal agencies. The price will not be ridiculous. The most important thing is that they basically do not require recharge. Card!

What is the standard for permanent hair removal?

Permanent hair removal is a standard definition by the World Health Organization. It refers to the treatment of hirsutism patients by laser pulverization to extract melanin to make the hair atrophy and fall off and finally reach a clinical end point, forming yellow-gray small villi that cannot be recognized by the naked eye. It can be maintained in a relatively stable state for a long time.

Specific characteristics of men's hair

The hair of ordinary girls, a small hair needs 5 to 6 consecutive lasers to hit, remove the melanin, the hair may not grow, but boys are male individuals, and the male hormone is very strong, and the hair removal people are all in puberty , Adolescence, all young adults, his hair is very, very thick, very, very lush, after giving him a course of stimulation, it can be relieved a lot, and some even no longer grow. However, due to individual differences, some boys will keep growing. If the clinical end point is achieved (fine villi are visible), it may take two courses of treatment, that is, a stimulation of continuous lasers that requires 10 to 10 times, which is impossible with ordinary machines, because men’s melanin metabolism is relatively fast , The wavelength of another ordinary machine can't reach the bottom of the hair follicle. It removes a relatively small amount of men's melanin, which is almost negligible for men's hair removal. Only by choosing a laser, can it be targeted for men's hair treatment.

Traditional hair removal shops, men's hair removal problems

The first must be to avoid cross-infection. Now whether it is a hospital or a traditional beauty salon studio, relatively speaking, the environment is very mature, and there are many people doing hair removal, but there is a risk of cross-infection in traditional stores. .

Why it doesn't last long after men's hair removal

Why does it happen that men can't keep it for too long after taking off? What I am referring to is the case where there are signs of recurrence for more than one year. Generally, two cycles of laser damage to the hair in a row can be used to remove even the stubborn hair, even the troublesome patients with hirsutism. Why does it relapse a little after a few years? This is indeed related to male hormones and metabolism because permanent hair removal is not bald, but ultimately small villi. Even if you live in this world for a second, your body is rapidly metabolizing, continuously generating new melanin supply to nourish every hair in your body. Your hair includes the hair in the part you shed. Although there is no melanin in the hair follicles of the part you have done at this time, there will be no hair in the short term, but the production of new melanin will wake up the shrinking hair follicles and form new villi. Boys who achieved permanent clinical endpoints could re-consolidate the laser every one to two years depending on their needs. If it is a beard, it is quite special. This part is said separately. In the later stage, for beauty seekers, if the face is no longer used with a razor, then because the face is an exposed part and receives more ultraviolet rays, and the boys have been shaving for many years, it is more annoying than the beard grows more and longer. of. After taking off, don't shave at this time, you can only pull out the small hairs. Too much and go to the laser. The frequency will not be as high as before. No more once a month. No matter how difficult the hair is, as long as you give enough energy, it can be removed eventually. The beard takes longer than ordinary parts, so you must be patient. Of course, if you play basketball on the beach and sunbathe in the hot sun every day, I suggest you not. Good for hair removal. Although men's hair removal is relatively difficult to remove, it is not that it cannot be maintained for a year and then recurs. I mean that men's hair removal cycle is relatively long. But it is possible to do permanent hair removal. I have a lot of cases that have been tracked for a few years and have not grown any more. Of course, there are small fluff, just like the small fluff on the lips of girls, it is not very obvious. There are really Virgo babies who strive for perfection. That's really a fluff that can't be tolerated, haha, not a black virgin. Consolidation for one to two years can also make the face smoother and cleaner. The reason why other men's men are not very effective is because of the problem of the machine, and the professionalism of the operator.

Does laser hair removal have the function of rejuvenating skin and shrinking pores?

The real laser will not damage the skin and sweat glands. The light energy is mainly absorbed by the epidermis and dermis pigment tissue selectively so that the pigment body disintegrates and shatters. After being phagocytosed by macrophages, it is excreted through the blood and lymphatic circulation to play a therapeutic role. It does not cause any damage to adjacent tissues.
