Acne is commonly known as pimples, and although some people laughingly call it “the color of youth”, it leaves behind acne marks and scars that seriously affect the “face” of acne sufferers. Fractional laser can effectively solve the “face” problem. Fractional laser is the latest invention in the field of laser medicine, which uses a new laser technology for topical treatment, applying laser energy to penetrate deep into the skin to treat lesions and promote collagen regeneration. The fractional laser is able to deliver laser energy in segments, avoiding the damage to normal tissues caused by the over-concentrated energy of traditional laser therapy, while promoting the healing process of the skin and enabling patients to resume their daily activities in a shorter period of time. Fractional laser treatment for acne has the advantages of good efficacy, short treatment course, less pain, and low recurrence rate, etc. It is currently being carried out in foreign countries.
