However, the specific fading time is related to the causes of pigmentation and personal constitution, as follows: 1. Patients who suffer from pigmentation system diseases and have pigmentation rebound after laser treatment, the fading time is usually about 6-12 months; 2. Patients with simple pigmentation can fade after treatment, usually about 6 months. After laser blemish removal, you should take good protective measures, develop good habits, exercise to help promote blood circulation, do not exfoliate for six months, and pay attention to sun protection to avoid the secondary precipitation of melanin after surgery to accelerate the generation of facial pigmentation or other skin problems. Outdoor activities can be combined with sunscreen products or the application of vitamin E capsules to help reduce the production of melanin. The use of medication to promote depigmentation is generally not recommended and it is sufficient to let the pigment fall off naturally. The skin is fragile after surgery, so it is important to avoid scratching, rubbing and irritation with hands. Therefore, it is recommended that candidates seek treatment at professional medical institutions to obtain safer and more effective treatment results as possible.
