We're not sure why the 42-year-old former "Baywatch" babe (you might recall that the show revolved around Anderson running on the beach in a revealing one-piece) and Malibu resident skips sunscreen, since Skin Cancer is the most common cancer in the U.S.
But we do believe that the star skipped Botox -- she has the lines and wrinkles to prove it.
Still, we suspect those famous lips saw a surgeon at one time or another -- especially since Anderson was the postergirl for larger-than-life features (specifically her lips and breasts) throughout the Nineties.
Do you think Pam has had work done on her face? Do you think it's stupid to not use sunscreen? Leave a comment below!
