What is the role of hydrocolloids in hypertrophic scars and keloids?
Silicone gel sheeting has been investigated for use in the treatments of keloids and hypertrophic scars. Its mechanism of action may be related to scar hydration. One randomized controlled prospective study set out to evaluate a hydrocolloid occlusive dressing that also acts by promoting a moist environment. Scar size and volume, color, patient symptoms, and transcutaneous oxygen measurements were taken. The study found significantly reduced itching, reduced pain and increased pliability for both treatments, used over two months. The authors concluded that hydration of the scar offered symptomatic improvement, but no change in physical parameters. Reference: Phillips T. J., Gerstein A.
