Immediately after laser treatment, please follow the doctor’s instructions to apply cold compresses to reduce thermal damage and minimize side effects. If there is blistering or crusting after laser treatment, you should not scrub with water for 3-7 days in principle. Protect the cleanliness of the wound surface, and use topical anti-infective and healing-promoting drugs to clean it. Premature artificial scab removal is prohibited and should be left to fall off on its own. Sun protection and moisturizing, avoid direct sunlight ultraviolet radiation. Some patients develop hyperpigmentation after treatment, which will generally fade away after 1-6 months depending on individual circumstances. If you have any special discomfort, please follow up promptly.
