When can i start tanning naturally?

I would say wait a little while longer before tanning outside. It is still considered winter so we are the farthest away from the sun. I would say in March you should start. I would probable try a new self tanner, or the new lotions fromJergens that builds a tan slowly over the next week. Then you will have a little color and then can make the "most" of your time in the sun, when the rays are a little stronger!
