If i wear zinc oxide in the tanning bed on my face, will that help prevent skin cancer?

Avoid tanning : As a dermatologist, i always advocate for sunscreen use to prevent skin cancer. However, even more important than that is avoidance of tanning beds. Sunscreens do not protect you 100%, so much of the uv rays in the tanning bed is stil getting thru. Your tan is a sign that damage has been done to your skin and your skin is trying to protect itself with more pigment. So ditch the tanning bed!
