Abstract：Objective To observe the effect of treatment that 1540 nm fractional laser combine with human-like collagen dressings superficial depressed scars after acne.Methods 60 patients with superficial depressed scars after acne were selected as subjects.All of them have less than one year disease course.1540 nm fractional laser was ap-plied for the treatment with a variety of different parameters and the energy.And laser treatment once every two weeks,continue for four times in all.Then patients were divided into experimental group (36 cases)and the con-trol group (24 cases ).Test group use humanoid collagen dressings,non-woven pure water mask is used for control group immediately after laser treatment for 15 to 20 min.This treatment last for 15 to 20 min every night, which continue for 5 days.Results The efficiency of test group for scars is 91.67%,and effective rate of control group is 62.5%,the efficiency of experimental group is much better than the control group (P<0.05).No clini-cal difference between the two groups after treatment for erythema score (P > 0.05).Satisfaction of patients in test group for moisture,smoothness is much higher than patients in control group (P <0.01).Conclusion 1540 nm fractional laser has non-invasive and light pain,postoperative appearance has not effect for patients′work.At the same time,the treatment without the risk of pigmentation.When combined with human-like collagen dress-ings,there is no significant side effects and patient compliance is good.As a result,this kind of treatment is suit-able for patient who is sensitive to pain of has no time for rest.
