Laser acne marks need a recovery period of 1-3 months. Postoperative nursing will affect the recovery time of laser acne marks. It will be ugly before recovery, because two days after laser acne marks, all wounds on the skin will have red marks. After laser scabbing, it can not be peeled off by itself, so as not to affect the wound recovery, and even bring new bacteria to cause pigmentation. Moreover, the softening time and shedding time of laser scar removal are different. The most important thing is to pay attention to sun protection during slow skin repair. Be sure to wear sunscreen and take an umbrella when you go out. Because once exposed to ultraviolet light, it will cause pigmentation and deepen skin color.
