Ice point hair removal is a kind of hair removal surgery, which mainly uses high temperature to destroy the melanin in the hair follicle and affect the regeneration of hair, with little damage to the local skin. Although most of the candidates have no obvious uncomfortable reaction, there are still certain hazards of this method, as follows: 1.Improper postoperative care, resulting in local skin secondary infection; 2.Allergic reaction, resulting in eczema-like changes; 3.Local hair follicles are stimulated, causing pigmentation, pore size and skin color changes; 4.Redness of the hair removal site, the appearance of follicular edema, manifested as a small wind mass-like changes . If the energy is too high or repeatedly treated, blisters, crusts and even scars may appear on the hair removal site. To avoid these hazards, ice packs should be applied for a period of time after treatment to minimize local temperature and discomfort. If the redness of the skin persists and even blisters appear, you should seek medical attention promptly. In most cases, there is only slight local redness and follicular edema, which can subside quickly.
