Well I will give you the safest way which is to not tan at all. Getting too much sun causes wrinkles that while we are young now doesn't seem to worry us but it will in the next 10 to 15 years. I say go with sunless tanning solutions. Jergen's makes a terrific lotion that has a light shimmer. Loreal has a great one for just your face. You should also buy bronzer and use that instead of blush. Another option is to go to a tanning salon and get the spray tanning solution sprayed on you. It lasts usually 3 to 4 days depending but is not very expensive and is perfect for a special event where you want to look like you just came back from the beach. Trust me and stay away from the tanning beds and sitting in the sun. If you really insist on tanning in the sun then use SPF 30 or even higher like 45.
