Fractional lasers are categorized into non-exfoliating fractional lasers and exfoliating fractional lasers, and the two types of lasers have different recovery times after treatment. Generally, non-exfoliative fractional laser recovers faster and can be fully recovered in about one month after treatment; exfoliative fractional laser has a longer recovery time and takes 3-6 months to recover. Fractional laser is a more common skin cosmetic technology nowadays, which can effectively solve a variety of skin problems, for example, it can get rid of pigmentation, fine wrinkles, acne marks and pits, as well as scarring and so on. Non-exfoliative fractional laser treatment, with less damage to skin tissues, is mainly used for pigmentation, fine wrinkles, etc. Generally, the epidermis will form a more stable point-like scab in 1-3 days, and the normal appearance will be restored after the scab falls off in 3-6 days, and the regeneration of the internal dermis layer can last for 1-3 months. Peeling fractional laser treatment is more damaging to the skin, mainly used for the treatment of acne marks, scarring, etc. The recovery time is usually slower, usually it takes 3-5 days to form a more stable scab at the treatment site, and the scab will fall off by itself in at least 10-14 days. Fractional laser treatment should strictly follow the doctor’s instructions to do a good job of care, such as keeping local skin clean and hygienic, but also strict sunscreen, regular work and rest, dietary supplement vitamins and proteins, is conducive to recovery.
