Freezing point depilation needs a lot of treatment, but it won't hurt the skin no matter how many times it is repeated. Because laser energy can only be absorbed by melanin in hair follicles, it will not cause more harm to the skin, except for people with darker skin color.

main problem
First of all, freezing point hair removal is suitable for some people with light skin color but dark hair color. If your skin color is dark, the laser will destroy the skin pigment, resulting in the formation of black spots or white spots, but it will basically return to normal after a few months. Therefore, you should choose a regular plastic surgery hospital and an experienced doctor before freezing point hair removal.
Secondly, in the process of freezing point depilation, a few patients may have temporary redness, mild swelling or mild itching, which is a normal reaction and can return to normal within a few hours after operation.
