Does IPL camouflage skin cancer?

These are good reasons to see a dermatologist for you skin treatments especially if you have considerable sun damage and have already had at least one skin cancer.  Early detection and treatment of skin cancers can keep you out of trouble.  A dermatologist who also does your cosmetic treatments can also do you cancer screen on a regular schedule. 

IPL is attracted to pigment. So when you are passing over a light-colored area of skin, and get to a mole or pigmented area (like a skin cancer sometimes), it can overtreat and burn that section of skin because the light is targeting the melanin in that portion.
