Light medical beauty is a relatively new beauty project, which is mainly a way of skin care through non-surgical means. Its main characteristics are non-invasive, no side effects, safety and reliability, and rapid recovery after operation, so it is widely used. There are many projects in light medical beauty, such as laser, radio frequency, injection, filling and chemical peeling, all of which belong to a minimally invasive treatment. But for the sake of safety, we must choose a regular medical institution or a doctor with professional and technical level to avoid adverse reactions.
