Application of collagen and hyaluronic acid dressing in erbium fractionated laser for the treatment of atrophic facial acne scars

Objective To evaluate the application of collagen and hyaluronic acid dressing in erbium fractionated laser for the treatment of atrophic facial acne scars. Methods A total of 46 patients with atrophic facial acne scars were divided into two groups (n=23): an experimental group and a control group. The experimental group underwent erbium fractionated laser followed by external application of collagen and hyaluronic acid dressing within 20 min for seven days. In contrast, the control group was covered with saline-soaked gauze, while other treatments were the same. The patients were followed up for three months, while their acute inflammatory response, scab shedding time, patient comfort, the incidence of hyperpigmentation, the red areas assessment with VISIA skin tester, and other adverse reactions were assessed. Results The experimental group showed improvement in acute inflammatory response score and patient comfort (P<0.05), as well as decreases in scab shedding time, the incidence of hyperpigmentation, and the red area score under VISIA, compared with the control group (P<0.05). Conclusions Application of new collagen and hyaluronic acid dressing in erbium fractionated laser for atrophic facial acne scars can fasten the recovery of postoperative skin erythema, shorten scab shedding time, accelerate wound healing, and improve patient comfort.
