Efficacy and Safety of Intralesional Normal Saline in Atrophic Acne Scars

Objective: To determine the efficacy and safety of intralesional injection of normal saline in mild to moderate atrophic acne scars. Methods: Thirty patients having mild to moderate atrophic acne scars according to quantitative grading system were enrolled. Photographs were taken before and after each session. Injections of normal saline were given at weekly interval for 10 sessions. 4-10 ml was injected depending upon the number of scars. Efficacy was assessed after last session. Side effects, if any, were also recorded. Results: Out of 30 patients, mean age was 25.83 +/- 4.32 years. 9 (30%) patients were male and 21 (70%) patients were females. 7 (23.3%) patients had mild acne scars while 23 (76.7%) patients had moderate acne scars. Efficacy was observed in 25 (83.3%) patients while safety was noted in 26 (86.7%) patients. Conclusion: Intradermal injection of normal saline into atrophic facial scars can be used as safe and effective treatment.
