The silicone products are called cica care (S+N), and I think there is a another version from a company called Molnycke called mepiform. Cica care is about �20 for a month, the other one is cheaper sightly I think. They work only on certain types of scars, called hypertrophic or keloid scars. To you and me, this means raised pink scars. They can be used whether the scars are recent or old and have a good success rate (marginally higher if new). The molnlycke one is available on the NHS, though I do not know about cica care. They both require an extended period of treatment, (2months+) and nobody really knows why/how they work, despite what the manufacturers say! If the scars are of a different type, these products will NOT help.
