Abstract:
Objective To evaluate the effect of resurfacing facial atrophic acne scars with 2790 nm YSGG fractional laser.Methods 38 patients with facial atrophic acne scars were treated with the 2790 nm YSGG fractional laser.All patients were randomly divided into two groups:group A using the combination with ablative and non-ablative mode of treatment; group B only using the non-ablative mode throughout the entire face,four treatment sessions for each patient,6 weeks interval.Comparative photographs were taken by using VISIA.Specific complexion analysis was used to identify and quantify depressed scars and texture,and patient satisfaction was graded with a 4-point scale.Results All of facial atrophic acne scars obtained different degree of improvement were treated by 4 times.In groups A and B,cure rate achieved 56.0 ％ and 30.8 ％,respectively.All the 38 patients had a chieved efficacy (81.6 ％),and they were satisfied with the results (84.2 ％).No severe side effect was observed.Conclusions 2790 nm YSGG laser is easy to manipulate and is more exactly than other lasers.It is especially effective in enhancing the clinical outcomes of scar revision with less complications and pigmentation,and thereby 2790 nm YSGG fractional laser can provide the patients with superficial scar in face as an additional therapeutic option.
