Keloids and hypertrophic scars are fibroproliferative disorders of dermal tissue after skin injury. Many clinical control studies have reported evidence that silicone gel is effective in preventing and alleviating hypertrophic scarring. Whether silicone gel sheeting prevents hypertrophic scars or keloids requires clear evidence of its clinical effectiveness. ⋯ There was statistical significance in the effectiveness of silicone gel and silicone gel sheeting on the prevention of keloids or hypertrophic scars, especially in skin lesion wounds. However, most of the trials evaluating silicone gel sheeting or silicone gel as a prevention of hypertrophic scars and keloids had poor quality with high or uncertain risk of biases either in study design or in conduct.
