| Scars result when the skin repairs wounds caused by accident, disease, or surgery. They are a natural part of the healing process. The more the skin is damaged and the longer it takes to heal, the greater the chance of a noticeable scar.
The way a scar forms is affected by an individual's age and the location on the body or face. Younger skin makes strong repairs and tends to overheal, resulting in larger, thicker scars than does older skin. Skin over a jawbone is tighter than skin on the cheek and will make a scar easier to see. If a scar is indented or raised, irregular shadows will be seen, giving the skin an uneven appearance. A scar that crosses natural expression lines or is wider than a wrinkle, will be more apparent because it will not follow a natural pattern nor look like a naturally occurring line.
Mederma works great on new scars, however, it's not as effective on the old scar. Using silicone-containing gels, creams, and bandages have also been helpful in reducing scar thickness. Many other techniques involve the use of skin grafting, laser surgery, dermabrasion, chemical peels, and microdermabrasion. |
