When you get a cut or have some sort of surgery, it takes time for the wound to heal and scar to form. After a wound closes, excessive water loss occurs for up to two years to reform itself.
As your skin attempts to heal itself, it starts to dehydrate which tells the cells in your skin to produce collagen. The more water loss that occurs, the more excess collagen is produced.
When too much collagen is formed, it causes raised scarring. The collagen is trying to thicken that part of the skin to reduce water loss. If left untreated, the thickened section will form a keloid scar.
When a silicone sheet or silicone scar gel is applied to the scar, it stops water loss and reduces collagen production. This can result in a softer, flatter scar and helps protect against bacteria.The science of scarring and how best to prevent scarring from becoming unsightly is a simple explanation which revolves around the amount of hydration in your skin cells and using silicone to prevent the loss.
