Is laser hair removal harmful to the skin?

Laser hair removal is one of the most long-lasting hair removal technologies. But you should know that while it can remove unwanted hair, laser hair removal can also cause some adverse effects on the skin. For example, temporary redness and swelling are common. In addition, scarring and skin discoloration can occasionally cause more serious side effects.

Laser Hair Removal Precautions

Ice compress after laser hair removal

Ice compress is needed after laser hair removal. This is because laser hair removal uses high energy to act on the skin, which may cause slight redness, mild edema or epidermal damage. Not only that, laser hair removal will also stimulate the expansion of pores, and ice compress can promote the contraction of pores. Many girls do not feel anything unusual after laser hair removal, so they do not apply ice compress. However, this is the most important thing to pay attention to after laser hair removal.

Skin needs to be hydrated after laser hair removal

After laser hair removal, the skin needs to be hydrated. This is because laser hair removal causes water loss in the skin. This is why many girls have tight skin after laser hair removal. Since the skin after laser treatment is more fragile, it is not suitable to use more irritating skin care products. It is best to use pure plant skin care products. Since the skin is dehydrated after laser treatment, it is generally recommended to use hydrating skin care products to increase the water content of the stratum corneum, repair the surface skin, rebuild the skin barrier and anti-irritation, anti-inflammatory and other functions.

Do not eat spicy food after laser hair removal

Do not eat spicy food after laser hair removal. Since the skin after laser hair removal is extremely fragile, irritating food can cause allergic reactions on the skin after laser hair removal. Irritating foods include: chili, pepper, garlic, etc. It is worth noting that after laser hair removal, it is best to eat less black food, such as soy sauce, coffee, etc., to avoid the deposition of melanin.

Pay attention to sun protection after laser hair removal

After laser hair removal, you need to pay attention to sun protection. This is because after laser hair removal, the stratum corneum of the skin becomes thinner and the skin is in a very sensitive period. The ultraviolet rays in the sun will directly stimulate the melanocytes in the basal layer of the skin. The stimulated melanocytes will produce a large amount of melanin, causing pigmentation. Therefore, sun protection is very necessary after laser hair removal. Generally, the sun protection period is 3 months.

The harm of laser hair removal to the body

The growth of human hair is mainly controlled and restricted by androgens and estrogens, which have specific stimulating or inhibiting effects on the growth of hair in different parts of the body, so the distribution of hair in men and women is different. This situation may be caused by excessive secretion of androgens. It is recommended that you go to the hospital for examination to understand the endocrine situation.

Laser hair removal will cause some harm to the human body, because the skin and cells affected by the laser will be damaged. The root cells of hair tissue will be damaged and will fall off the body. However, the degree of damage varies from person to person. Generally, people in good health do not need to worry too much, as laser hair removal will not leave scars.

The harm of laser hair removal is related to the laser used in laser hair removal. Commonly used lasers for hair removal include long pulse ruby ​​laser, long pulse Alexander laser, long pulse diode laser, long pulse rubidium chromium laser and pulsed light. Since hair removal laser only destroys hair follicle cells in the growth phase, it does not completely destroy hair follicles in the resting phase and degeneration phase, so some hair follicles will regenerate.

The human skin is a relatively transparent structure. Plastic surgery experts have found in clinical experiments that in the face of powerful lasers, the skin is simply a piece of transparent cellophane. Therefore, the laser can penetrate the skin very smoothly and reach the hair follicles. Since the hair follicles contain a lot of melanin, they can preferentially absorb a large amount of laser energy and eventually convert it into heat energy, which increases the temperature of the hair follicles and achieves the purpose of destroying the function of the hair follicles.
