Laser hair removal is based on the principle of photothermal dynamics. By adjusting the laser wavelength, the laser can penetrate the surface of the skin and reach the hair follicles. After being absorbed, the light energy is converted into heat energy, which damages the hair follicle tissue and causes the hair to lose its regenerative ability. Laser hair removal is a relatively mature hair removal method, and there are also many precautions after laser hair removal, including protecting local skin and paying attention to local sun protection.


1. Protect local skin: Laser hair removal can cause a certain degree of thermal damage to the skin, and after laser hair removal, the skin is in a sensitive state that is prone to damage. Therefore, it is necessary to pay attention to protecting the skin and not excessively rubbing, massaging, or squeezing the skin in the hair removal area, which may cause damage to the skin. It is also not advisable to take a hot bath, as hot water may worsen the burning sensation of the skin, or may cause skin damage and form local scars;


2. Pay attention to local sun protection: In the state of laser hair removal, it is possible that due to local thermal damage to the skin, the skin pigment cells are in an active proliferative state, which is easily stimulated by external ultraviolet rays, causing an increase in pigment. Therefore, when going out, it is necessary to wear a sunshade hat, apply sunscreen locally, and wear sunglasses to reduce the possibility of pigmentation and avoid skin pigmentation;
3. Adjusting dietary structure: Avoid eating spicy and stimulating foods, and pay attention to supplementing vegetables and fruits appropriately in your diet, such as carrots, kiwifruit, apples, oranges, etc. Vegetables and fruits are rich in nutrients such as vitamin A, vitamin C, and vitamin E, which can play a certain role in helping skin recovery;


4. Regulating lifestyle: After laser hair removal, avoid staying up late, ensure sufficient sleep, and avoid excessive tension, anxiety, depression, etc., which is not conducive to skin recovery.
Laser hair removal can have the effect of reducing hair, lightening and thinning the color, as well as lengthening the growth cycle. Most people have no hair growth within 3-5 years after laser hair removal, and 1-2 small hairs may appear locally, but it will not affect the overall appearance.
