My grandmother developed skin cancer on her face, arms and legs as a direct result of "tanning" with baby oil as a teenager. Two of her best friends, who also tanned with her, developed skin cancer as well.

It ended up not being fatal, but the treatments and laser removal process were incredibly painful for her. Not to mention, expensive & time consuming.

I don't go out of the house without at least my SPF15 daily moisturizer, lemme tell you.
