@starship Welcome to Mayo Clinic Connect. Having precancerous spots on your face, neck, hands, or other exposed areas often means using a liquid nitrogen to "freeze" them off, and hopefully prevent them from returning.

Like your mom, I seem to get these occurrences all the time on my face. Yep, they freeze them off each time. But I also have the fluorouracil prescription to use a couple of times a year. My experience is the following: Being a redhead, with very sensitive skin, I react pretty dramatically to the lotion! While I use it on the spots I know about, it will also react to spots not always visible to your naked eye, so you can get a widespread reaction. The first time that happened, I panicked! But my dermatologist assured me that was the medication doing the job it was supposed to do. There aren't any unpleasant side effects other than looking blotchy in my face, and for me, knowing it is doing its job lets me look past any discomfort. I do it once a day, not twice. If it is important, using a lightweight powder concealer or foundation may help her feel less noticeable.

I use a sunscreen everyday all year around. As a malignant melanoma survivor, I know that keeping tabs on your skin health is important! Wearing long sleeves, hats and sunglasses, and staying out of the harmful rays of the sun are also good precautions.

Do you have any further questions for me?
