how do u get soft and fair skin?

It depends on your age. If you're late teens or early twentys the answer is simple; stay out of the sun and if you have to go out in it, wear a strong sun screen. If the sun damage is already done, try sorbalene. I'm 64 and often get mistaken for a much younger man. I attribute that to the fact that I rode US Navy Submarines for much of my adult life. No sun. I've been in Australia for twenty years now and the ravages are begining to show.
