The Doctors watch a video from a viewer, Christine, about spots she has all over her legs and the back of her arms. Christine thinks the spots may have something to do with her love of the sun. She says she has tried PDL (laser) treatments but her arms still look horrible. She wants to know if there is anything she can do to get rid of these spots.
Dermatologist Dr. Sonia Batra explains while stopping tanning is a good thing, the spots have nothing to do with sun exposure or ultraviolet light! They are a very common, completely harmless overgrowth of the skin called seborrheic keratosis. It is believed to be genetic and people often get them as they get older.
Dr. Batra says people can try many ways to remove them like scraping, freezing with liquid nitrogen, and using a blade, but unfortunately, they often come back. In Christine's case, wherever they've traumatized her skin, she's been left with a red footprint, which is common for people with fair skin tones, like hers. Someone who is darker skinned may have hyperpigmentation and be left with dark spots.
For Christine, it seems like she has been treated properly but the marks she has now are the red footprints that will take some time to fade.
