Laser pimple pit removal is to stimulate the skin of pimple pits through the photothermal effect produced by laser to promote collagen regeneration of pimple pits and achieve the effect of smoothing pimple pits. Fractional laser is usually used to remove acne pits, including both ablative fractional laser and non-ablative fractional laser, which can usually achieve significant results, but the two are targeted differently and the results are significantly different. The exfoliative fractional laser is suitable for the more serious pits and has a relatively good effect, but it is more damaging and bleeding, with a longer recovery period and requires multiple treatments. The non-ablative fractional laser is suitable for superficial and small acne pits, which basically does not bleed and causes less damage to human skin, and has a better effect on these pits. Fractional laser is a non-invasive laser treatment that takes only tens of minutes per treatment, which has the advantages of fast and significant effect of invasive treatment, but also the advantages of non-invasive treatment with small side effects and short recovery time. It is recommended to go to a regular hospital for laser acne pit removal treatment, and to pay attention to a light diet and sun protection after surgery to avoid affecting the recovery effect.
