SILICON SHEETS

The role of silicon sheets in improving raised scars symptoms discovered more than 30 years ago. Since then Silicone-based products are widely used in the management of hypertrophic scarring and keloids. However, many studies have been done in field of silicon efficacy, show their incomplete effectiveness in diminishing different kinds of scars.

  • Mechanism of Action
  • Limitations
  • Complications
The mechanism of action of silicone-based products in scar management has not been completely determined, but the following processes are proposed for them:

1) An increase in skin surface temperature could be involved because skin surface temperature could increase tissue collagenase activity and lead to collagen destruction.
2) Development of a static electric field also may be involved, because it has been proposed that the negative static electric field generated by friction between silicon sheets and the skin could cause collagen realignment and result in the involution of scars.
Note: There is no evidence currently that the static electric field produced by silicone products causes changes in the extracellular matrix of scars.
3) Silicon decreases evaporation of water from the skin and increases hydration of the stratum corneum. Skin moistening might reduce collagen synthesis, hyperemia and inflammatory factors accumulation which prevent hypertrophic scar formation.
4) Beneficial effects of silicon sheets on scars are also mediated by changes in oxygen tension which prevent tissue over vascularization

As it’s been mentioned, silicon sheets mostly have preventive role in hypertrophic scars and keloid formation. They are more effective on new, immature scars and in few range of people; furthermore study shows that silicon could improve scars symptomatically (redness, pain and skin itching) and have actually no effects on other parameters like scar thickness and color.
