Scars are one of the beauty spoilers that we want to get rid off. There are several brands of scar sheets sold over the counter now. These adhesive patches contain silicone, which can soften scars. They work best on raised (hypertrophic) scars, and are not to be used until the scar heals. Silicone patches must be worn for at least eight weeks to get results. There are also topical gels available that help reduce such scars.
Flat scars (normotrophic) are the same height as the surrounding normal skin. Old, flat scars are the most difficult to get rid off. Such a scar can sometimes be improved by a medical doctor specializing in dermatology, who can determine what results can be expected with which of the many new procedures available, such as laser resurfacing. A depressed (hypotrophic or atrophic) scar can be raised by a hospital-affiliated dermatologist by injecting collagen beneath it.
