Wounds and Scars

Skin serves an essential function for humans.  It is an important barrier against microorganisms and also helps regulate body temperature.
When the integrity of the skin tissue is compromised (accidents, surgery, etc...) wounds occur.  In response to the damage, the body attempts to
repair the wound in four major phases: inflammatory, proliferative, contraction, and remodeling.  Unfortunately, this process of healing gives rise
to scars.  Typically, scars lack hair follicles, sweat glands, are less elastic than original skin, and tend to be lighter in color.  Scars can be
classified as hypertrophic (raised scar within the boundaries of the original wound), keloid (raised scar that tends to extend beyond the
boundaries of the original wound), and hypotrophic (scar may be depressed and hyperpigmented).

Mederma

Mederma is a gel-based product that was developed specifically to help scars become smoother and softer.  It is available over-the-counter
(i.e., without a prescription) in the Campus Health Pharmacy.  The gel contains an onion extract which is thought to be the active moiety.  It can
be used on all types of scars including: surgical, burns, stretch marks, acne, and old or existing scars.  It should be applied 3-4 times daily for
2-6 months depending on the type of scar.  The data available are conflicting as to the effectiveness of Mederma in reducing the size and quality
of the ultimate scar.  The question still remains whether the act of massage or the onion extract contained in Mederma will decrease the
appearance of unsightly scars.  The manufacturer of Mederma offers a money back guarantee if an improvent in scar color, texture,
appearance, or flexibility is not seen within the recommended usage period.
