Skin is incredibly sensitive, which most people are aware of. It is easy to damage both by the sun and also through the wear and tear of living. Kids are always getting scuffed knees, and adults also have a few accidents here and there. Scars tell a story, but sometimes you want the scar that goes along with the tale to be less noticeable. One way to do this is to keep the cut moisturized.
Vaseline can be slathered on the cut as it heals to minimize scarring.
