It is based on the principle of selective photothermal action, using a new pulse pattern and repetitive frequency to penetrate the subcutaneous fatty tissue and act directly on the hair follicle, causing the temperature inside the hair follicle to gradually increase and gently inactivate the hair follicle to achieve the purpose of hair removal. Ice point hair removal avoids the two major problems of previous laser hair removal, namely excessive time and pain. Previous laser hair removal generally requires 2-3 times of exposure, with an interval of 1-2 months, which is too time consuming for many people to stick to. In contrast, ice-dot hair removal will not affect the sweat glands, nor will it cause any harm to the skin, and the operation process is more comfortable and painless for the candidates. However, it should be noted that half a month before the ice point hair removal, do not use other hair removal products, containing certain chemical substances, which will cause damage to the skin after use. After ice-dot hair removal, there will be slight local redness, swelling and pain, which is a normal phenomenon, and generally after 1-2 days, the symptoms will naturally subside. If the pain is serious, candidates can use ice to reduce the pain. In addition, candidates need to avoid sunlight within six months after surgery, do not wear clothes with too dark colors, and also avoid spicy and stimulating food.
