What works most effectively to use to get rid of marks on skin left by insect bites?

Good skin care: The best way to minimize scarring of any type, whether a injury, bite, scratch - is good skin care. Keep clean, use moisturizers several times a day liberally, and use sunscreen, as sun and uv radiation exposure can make the marks look darker. Don't use tanning beds, and be careful if you are shaving the area not to use razors or methods that are irritating ot the skin.
