Silicone gel is mainly used for the treatment of proliferative scars caused by burns, trauma and surgery. It can cover the surface of the skin to reduce the rate of water evaporation, and further inhibit the proliferation of fibroblasts in the dermis at the scar tissue, so as to achieve the effect of inhibiting scar proliferation. 2. Sodium Heparin Allantoin Gel is suitable for hypertrophic keloid scars and scar tissues secondary to surgery, burns and acne.
