After laser hair removal, the skin has red spots and stings. What should I do? Is there any way to solve this problem? What measures and care should be taken after laser hair removal? Those people are not suitable for hair removal. Let me give you a brief introduction. Let's have a look.

After laser hair removal, the skin appears red spots and stings 1.

What is laser hair removal?

Laser hair removal is based on the principle of selective photothermal kinetics. By reasonably adjusting the laser wavelength and energy pulse width, the laser can pass through the skin surface to reach the hair follicle at the root of the hair, and the light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, so that the hair loses its regeneration ability, and may damage the surrounding tissues, resulting in light tingling. Laser hair removal is a safe, fast and lasting hair removal technology.

Laser hair removal is a less painful hair removal method among all hair removal methods. Before laser hair removal, there will be a stage of "irradiation test" to determine the degree of pain of the patient. The results of many clinical trials show that most patients only feel "bounced by a rubber band". Laser hair removal will cool the skin at the same time. There are many methods and principles of skin cooling, but all of them are at a temperature of about 4 degrees Celsius. Many plastic surgery hospitals promote freezing point hair removal to make you feel no longer painful. In fact, it is far from 0 degrees, because under the action of laser heat, a few degrees of contact makes people feel iced.

The above are some principles of laser hair removal, and the details that should be paid attention to if you feel the same way or have red spots after laser hair removal. Of course, laser hair removal should still be carried out in a regular hospital, and then leave the hospital or beauty salon when the body reacts.

After laser hair removal, the skin became reddish and stinging. Does laser hair removal hurt the skin?

Laser hair removal is one of the most lasting hair removal technologies. However, we should know that although laser hair removal can remove excess hair, it will also have some adverse effects on the skin. For example, temporary redness and swelling are common. In addition, it occasionally causes serious side effects such as scars and skin discoloration.

If we want to avoid the damage of laser hair removal to the skin as much as possible, first, we should choose a regular hospital for laser hair removal surgery, so that experienced doctors can make feasible hair removal plans according to their own conditions, followed by scientific postoperative care.

Laser hair removal is not suitable for people.

Laser hair removal has certain taboos, and these five groups of people must not do laser hair removal projects:

1, scar constitution, mild allergic constitution;

2. People with darker skin color are not suitable for laser hair removal;

People who have done wax hair removal and patch hair removal within 3.6 weeks;

4, menstrual period, pregnant women, people who are too old and too young are not suitable for laser hair removal;

5. Patients with ulceration infection and mental abnormality in hair removal area are not suitable for laser hair removal.

Matters needing attention in laser hair removal

Ice should be applied after laser hair removal.

Ice should be applied after laser hair removal, because laser hair removal acts on the skin with high energy, which may lead to skin redness, mild edema or epidermal damage after laser hair removal. Not only that, laser hair removal can also stimulate pore expansion, and ice compress can promote pore contraction. Many girls don't feel anything unusual after laser hair removal, so they won't ice compress. However, this is the most important thing to pay attention to after laser hair removal.

After laser hair removal, you need to replenish water to your skin.

After laser hair removal, you need to replenish water to your skin. This is because laser hair removal leads to skin moisture loss, which is also the reason why many girls feel tight after laser hair removal. Because the skin after laser is fragile, it is not suitable to use skin care products with greater irritation. It is best to use pure plant skin care products. Because the skin is short of water after laser, it is generally recommended to use a series of skin care products to increase the moisture content of the stratum corneum, repair the superficial skin, rebuild the skin barrier, and resist irritation and inflammation.

Don't eat spicy food after laser hair removal.

Don't eat spicy food after laser hair removal. Because the skin after laser hair removal is extremely fragile, irritating food will have an allergic reaction to the skin after laser hair removal. Irritating foods include: pepper, pepper, garlic, etc. It is worth noting that after laser hair removal, it is best to eat less black food, such as soy sauce and coffee, to avoid melanin deposition.

Pay attention to sun protection after laser hair removal

Pay attention to sun protection after laser hair removal, because after laser hair removal, the cuticle of the skin becomes thinner, and the skin at this stage is in a very sensitive period. Ultraviolet rays in sunlight will directly stimulate melanocytes in the basal layer of skin, and stimulated melanocytes will produce a large amount of melanin, which will cause pigmentation. Therefore, sun protection after laser hair removal is very necessary. The general sunscreen time is 3 months.

Harm of laser hair removal to health

The growth of human hair is mainly controlled and restricted by androgen and estrogen. Androgen and estrogen have specific stimulation or inhibition effects on the growth of hair in different parts of the body, so the distribution of hair between men and women is different. This situation can be thought to be caused by excessive androgen secretion. I suggest you go to the hospital for a check-up and get to know the endocrine situation.

Laser hair removal is more or less harmful to human body, because the skin and cells will be damaged after laser treatment, and the root cells of hair tissue will fall off from human body, but the degree of damage varies from person to person. Generally healthy people don't have to worry too much. Laser hair removal won't leave scars.

The harm of laser hair removal is related to the laser used in laser hair removal. Lasers commonly used for hair removal include long-pulse ruby laser, long-pulse Alexander laser, long-pulse diode laser, long-pulse rubidium-chromium laser and pulsed light. Because the hair removal laser will only destroy the hair follicle cells in the growing period, it will not completely destroy the hair follicles in the resting period and degeneration period, so some hair follicles will regenerate.

The human skin is a relatively light-transmitting structure. Clinical experiments by plastic surgeons have found that the skin is simply a transparent cellophane in front of a powerful laser, so the laser can penetrate the skin smoothly and reach the hair follicle. Because there is more melanin in hair follicle, it can preferentially absorb a large amount of laser energy and finally convert it into heat energy, thus increasing the temperature of hair follicle and destroying the function of hair follicle.
