What does it mean if my suburn turns purple-ish and hasn't gone away after a week?

If no itch nor pain,: And if it looks dry without any skin swelling, it may be on its way to healing. Rashes are difficult to describe in words, so patients usually need to have a doctor look at the skin. One should be sure to use moisturizers that contain sunscreen. (Avoiding exposure to the sun should let skin lighten up. However, one should take extra vitamin D to make up for not getting as much vitamin D from sun.)
