Want a safe tan? Just lie in the sun 1-5 minutes per side. That's enough to stimulate the melanocytes to produce tan. Really don't need to stay out so long and get skin cancer. I like to float in the pool for 1-2 minutes at a time and let the cool waters refresh me. Light skin in Asia is a sign of beauty and rich upper class. They don't work under the hot sun like rice farmers. Funny it's the other way around in the USA and Europe. Compare the monk's face who meditates all day indoors and the American Indian who is outdoors a lot. Another thing you should avoid is alcohol. It dehydrates your skin. You don't see it overnight but It adds up over the decades. I used to think wrinkled skin were found frequently in white people in cold winters. Not true. The cold winters make them bored so they drink a lot and grow older faster.
