I don't trust tanning booths. I'd use a product like oil of Olay's (sorry, brain fog day and can't remember its exact name.) I haven't had any experience with the spray on tans. Find out what kind of chemicals they use.
Remember, even with a fake tan, you HAVE to still put on sunscreen when you're out.
I've been totally staying out of the sun for twenty years now. I will be 50 on Halloween, but people never believe me when I tell my age, because my skin is so youthful. I used to bake, bake, bake in the sun when I was young, and I'm glad I stopped, because sun is the WORST thing you can do to your skin. PALE IS BEAUTIFUL!
