Laser hair removal is a beauty method that many female friends often do in our daily life. Many female friends will choose various hair removal products in summer. Laser hair removal has the best effect. Many people will choose to do laser hair removal. So is laser hair removal painful? Precautions for laser hair removal.

Does laser hair removal hurt?

Many women have experienced deep feelings after using laser permanent hair removal. It is performed under local anesthesia, so there is no pain, just some slight itching. After the laser permanent hair removal surgery, there will be some small bumps like being bitten by words, and the skin will turn red. These are normal phenomena and will slowly subside within 2 to 3 hours after the surgery. Therefore, laser permanent hair removal will not cause obvious pain.

Laser hair removal for calves and armpits. There will definitely be some pain, depending on the individual's skin color and the hardness and thickness of the hair. The darker the skin color, the more painful it is, and the thicker the hair, the more painful it is.

In fact, it is not important whether laser hair removal hurts or not. What is important is the postoperative care and the preparation before the operation. Before laser permanent hair removal, we must first check the physical condition. Some people with systemic diseases and skin allergies are advised not to take this operation. Also, avoid exposure to sunlight for a period of time after the operation and try to rest more.

Laser Hair Removal Precautions

First, shave all visible hair on the skin.

Laser is like a precise sniper, using a special bullet (wavelength) to aim at a target (melanin), while the surrounding passers-by A, B, C, and D (other skin tissues and structures) are not affected at all.

Due to the characteristic of melanin absorbing light energy, the hair in the hair removal area needs to be shaved before the operation. Otherwise, the local skin will feel a burning sensation due to the hair on the epidermis absorbing a large amount of energy, and even cause pigmentation in severe cases, which will not only increase the pain of treatment, but also affect the treatment effect because the melanin in the hair follicles absorbs less light energy.

The pain of shaved skin will be greatly reduced during treatment.

Need to complete a course of foot therapy

Some friends may only undergo two or three treatments, or even just one treatment, and fail to complete the entire course of treatment. Will this lead to hair growth?

The answer is: it will not cause rebound growth or thickening of hair, but the treatment effect will be covered.

With only one treatment, only the hair follicles in the growth phase are destroyed, and some of them can no longer grow terminal hair. However, since the effect of one treatment is limited, as time goes by, the hair follicles in the resting and regression phases enter the growth phase. In addition, due to the safety range of laser energy, not all hair follicles in the growth phase can be destroyed during the first treatment, and it seems that the hair density will be close to the original state.

Therefore, if you have only had one or two treatments, if you want to continue treatment after half a year, you still have to start from the beginning.

Before laser hair removal, you need to do some preparation

Avoid sunlight on the hair removal area and use sunscreen for more than 2 weeks.

Clean the skin in the hair removal area, remove surface grease, and shave all the hair (a razor can be used, shave close to the roots of the hair, and be careful to avoid scratches).

People who are particularly sensitive to pain can undergo surface anesthesia in advance, such as applying lidocaine cream.

Laser hair removal has minor side effects

There will be a slight stinging sensation during laser hair removal, and a mild burning sensation after the operation. Mild erythema and follicular papules will appear on the local skin, which will disappear within a few hours. Some patients will experience purpura, blisters, temporary pigmentation or hypopigmentation, and most of them will recover after a few months. In addition, because of the stinging, the painful stimulation may stimulate uterine contractions, so it is not recommended for pregnant women. Expectant mothers should wait.

The way to reduce the occurrence of side effects is to do a good job of sun protection before and after the operation, shave the epidermal hair before the operation, apply ice during and after treatment, and then use skin care ointment externally.

After laser hair removal, remember to apply sunscreen before outdoor activities.

What are the dangers of laser hair removal?

Causes redness and swelling

Redness and swelling are the most common side effects of laser hair removal, and are often accompanied by tenderness or pain. These reactions can be relieved by using painkillers or cold compresses under the guidance of a doctor, and under normal circumstances, the swelling will disappear on its own within a few days, so don't worry too much.

More sensitive skin

Almost all people who use laser hair removal will increase their skin's sensitivity to the sun's ultraviolet rays. Therefore, experts recommend that people who have just completed laser hair removal should avoid exposure to the sun for a few days to prevent skin damage. It is also necessary to use high-efficiency sunscreen for a period of time afterwards.

Causes blisters and burns

Less common, blisters and burns can also occur with laser hair removal. These problems are more common in darker skin types. Blisters and burns can also occur when the intensity of the laser is too high or when a particular skin type is treated for too long. These side effects are more serious because they can lead to infection or permanent scarring.

Causes scars

While scarring is not a common effect of laser hair removal, it can occasionally occur. When blisters open and the underlying skin is damaged, permanent scarring can develop. Typically, this side effect is caused by an inexperienced technician.

Skin discoloration

Skin discoloration is another common side effect of laser hair removal. Hyperpigmentation occurs when an area of ​​skin becomes darker than normal. Like blisters, this condition is more common in people with dark skin. This is mainly due to the destruction of melanin in the hair follicles during the laser hair removal process. Melanin is also responsible for producing skin pigment, and the more melanin there is, the darker the skin color. When melanin is removed, the skin color becomes lighter.

Laser hair removal interval

Laser hair removal is not permanent, so there will be an interval problem, so a second treatment is needed.

Since the melanin in the hair follicles and hair shafts selectively absorbs specific wavelengths, by using a properly adjusted laser instrument to irradiate the densely haired areas of the legs, the hair follicles will absorb the energy themselves and generate heat, gradually shrinking and ultimately losing the purpose of regenerating hair.

Through understanding the principle, we know that laser uses the principle of selective photothermal treatment for hair removal. However, due to the different hair growth cycles in different parts of the body, new hair follicles will grow new hair. Therefore, every once in a while, the parts that need hair removal need to be treated. After 2 to 5 cycles, the body hair problem is basically completely eliminated.

The interval between laser hair removal is based on the hair growth cycle and condition of different parts of each person. Generally speaking, each treatment should be separated by about 1 to 3 months. This will allow sufficient time for new hair follicles to grow hair. Laser hair removal is most effective for removing hair in the growth period. After one treatment, you can consult a doctor to find out how long it will take for a second treatment.
