Silicon gel sheeting for preventing and treating hypertrophic and keloid scars
There is weak evidence of a benefit of silicon gel sheeting as a prevention for abnormal scarring in high risk individuals, but the poor quality of research means a great deal of uncertainty prevails.
Keloid and hypertrophic scars are common and are caused by a proliferation of dermal tissue following skin injury. They cause functional and psychological problems for patients, and their management can be difficult. The use of silicon gel sheeting to prevent and treat hypertrophic scarring is still relatively new, and started in 1981 with treatment of burn scars. This review evaluates the effectiveness of silicon gel sheeting for preventing hypertrophic or keloid scarring in people with newly healed wounds, and for treating established scarring in people with existing keloid or hypertrophic scars.
