What is a Scar?
A scar is a natural part of the healing process, resulting from your body repairing a wound in the skin or other tissues of your body. The protein or collagen in normal, unscarred tissue lies in a random basketweave formation. In a scar, the collagen fibers form largely in a single direction. Scars are less resistant to ultraviolet radiation, and sweat glands and hair follicles do not grow back within scar tissues. Scar tissue is less elastic than unscarred tissue, and may also be visually unsightly. You might have scars on any part of your body that has been wounded in any way, the extent of scarring corresponding to the extent of initial damage. A scar may be raised, when the body produces too much collagen in healing, or sunken, as a result of chickenpox, accidents, or even acne. Sunken scars are caused when underlying fat or muscle is lost.
How Can a Scar be Reduced?
Because a scar is an injury to the dermis, or inner layer of skin, it is possible to remove the epidermis (outer layer) through chemical peels or mechanical and laser methods like dermabrasion or SmartSkin CO2 Fraxel, allowing new skin to regrow normally. Sunken scars can benefit from injections of dermal fillers. Raised scars can be more problematic, and you will want to chat with Dr. Nangrani about how to reduce and heal them.
