Laser hair removal is to use high-calorie laser to penetrate the skin, break the pigment particles in it, repair the damaged skin and stimulate subcutaneous collagen proliferation, so as to achieve the purpose of removing body hair. In order to ensure its best effect and safety, beauty seekers need to pay attention to the following points in their lives: 1 After laser hair removal, skin redness and itching may occur, which is a normal reaction and will disappear after a period of time. Never touch directly with your hands to prevent infection. You can use an ice pack or ice film to cold compress the hair removal part to reduce discomfort. 2.
