Abstract:
Background:Although silicone-based products are widely used for hypertrophic scar (HS) treatment, limited research exists on the correlation between patient compliance of silicone products and scar outcomes. This study aims to investigate whether continuous and consistent use of topical silicone gel (TSG) and silicone gel sheet (SGS) improves scar characteristics and whether patient compliance influences scar outcomes.
Methods:A total of 79 patients with HS were randomized into either TSG (n=38) or SGS group (n=41) by an independent physician who had not seen the patients. Patient compliance was assessed based on application frequency and duration. Patients were divided into three subgroups according to compliance. Scar characteristics were evaluated using the Vancouver Scar Scale (VSS) and patient self-assessment via a visual analogue scale (VAS) for 6 months.
Results:VSS pigmentation and scar height worsened in patients who applied silicone products for less than 3 days per week, especially in the TSG group. Patients who applied silicone products for more than 4 days per week showed significant improvements in all factors. Patients reported improvements in VAS scar height, pigmentation, and hardness as application time increased. Pain and itching improved regardless of application time.
Conclusion:Continuous and consistent use of TSG and SGS improved HS outcomes. Applying silicone products more than 4 days in a week correlated with better scar characteristics, except pain and itching. Applying silicone products less than 3 days in a week is not recommended, as this may worsen scar height and pigmentation.
