Silagen is an advanced, clinically proven system for both the treatment and prevention of scars, including hypertrophic scars, burn scars, and keloids. It creates a lightweight, self-drying, medical-grade silicone barrier that supports healthy scar healing. The proprietary silicone gel blend dries quickly into a flexible, gas-permeable, waterproof layer that helps regulate collagen production, encouraging smoother, more refined scar maturation and improving both the look and feel of the skin. With built-in SPF 30, it also helps protect scars from UV exposure and reduces the risk of darkening or discoloration. Important Information – Ingredients • Active: Zinc Oxide 20% (Sunscreen) • Other Ingredients: Polymerized Siloxanes (Silicone Gel), C12-15 Alkyl Benzoate, Polyhydroxystearic Acid My doctor recommended this for scars and it works so great! I bought in bulk and didn’t need these extras I got. This box is unopened and still sealed.
