Shaving leaves a small black spot is caused by the hair follicle hole opening of the hair is not completely removed, the patient does not need to worry too much, the hair will grow out gradually with time; can also be improved by photon hair removal, ice hair removal and other ways. 1. Photon Hair Removal: It utilizes the photothermal principle of intense pulsed light, using the melanin cells in the hair follicle to absorb light of specific wavelengths, thus selectively destroying the hair follicle to achieve the effect of removing the small black spots left behind after shaving. 2. Ice point hair removal: is based on the principle of selective photothermal action, the use of semiconductor pulsed laser and low-energy cooling system, in the semiconductor laser heating, destruction of hair follicles at the same time, the skin is cooled down, you can effectively remove small black spots left after shaving. Shaving leaves small black spots is a normal situation, do not worry too much, pay attention to care can be; if you feel the impact of aesthetic, it is recommended to go to a regular hospital standardized treatment.
