Fractional lasers are clinically effective, but the effects fade over time as the skin loosens and ages. No treatment is permanent. Through fractional laser, collagen reorganization and regeneration can be effectively stimulated and induced to help improve skin texture, which can be used to treat skin problems such as acne marks, fine wrinkles, skin aging, pigmentation, enlarged pores, dullness, etc., and it also has an obvious therapeutic effect on post-acne hyperpigmentation. But fractional laser if you want to achieve the ideal effect generally need multiple treatments, even if the ideal effect, but also with time and the physiological characteristics of aging, such as post-acne pigmentation after treatment completely disappeared, but also due to a variety of reasons leading to the face of the newborn acne, the inflammatory response is too strong, if the healing of the new pigmentation will be left behind. It is recommended to go to a regular medical institution for treatment and pay attention to scientific care after fractional laser treatment.
