How does this GFOUK Advanced Silicone Skin Renewal Gel Remove My Scar? The medical grade silicone in the GFOUK Advanced Silicone Skin Renewal Gel heals scars by increasing the hydration of the skin, which tells the body that it doesn't need to produce as much collagen. With the collagen that is produced, the silicone gel also balances the growth factors, so that excess collagen gets broken down in the healing processes.
