Ice point hair removal can achieve the effect of permanent hair removal, mainly for people with thick and dark hair. It mainly uses the selective photothermal action of laser to destroy the melanocytes in the hair follicles in the anagen phase, so as to make the hair follicles inactive and inhibit the hair regeneration. In general, the best results of ice point hair removal are the treatment of armpit hair. Many candidates can achieve the effect of permanent hair removal after about three times of treatment. However, after a few years, there will be fine local hair growth, mainly fine and soft, relatively light-colored Cui hair (cold hair). Other areas of hair, such as the trunk or limbs, are also treated well. Relatively speaking, lip hair removal is less effective and usually requires more than 5 treatments, each at an interval of about 6 weeks. Ice point hair removal is generally difficult to achieve the effect of complete hair removal at one time, it needs to go through repeated treatments, most parts need about 3-5 times, and the interval time or times for lip hair removal is longer. Beauty seekers should choose a regular medical institution, listen to the doctor’s arrangement and carry out hair removal treatment on time to achieve better results.
