Get a healthy glow with self tanner.
No matter what type of cancer you're fighting, rule number one for anyone going through chemotherapy or radiation is the same: stay out of the sun. Your skin becomes incredibly sensitive during these treatments, and your weakened immune system makes you more susceptible to sunburn. Even if you're naturally fair skinned, an extra-pale complexion—or even undertones of green or grey—caused by chemotherapy will make you look, well, really sick.
To give yourself a healthy glow, use a mild self-tanner on your entire body and your face. I particularly like this one from St. Tropez—you can see the color as you rub it on, helping to make sure that it goes on evenly.
