I have a skin condition in my face called malasma that I was told was the results of too much exposure of the sun. I found this puzzling because the one thing I do is stay out of the sun as much as possible. I was told it only took a small amount of exposure to be affected. In that case I would think that everyone would have the condition. What can I use to clear up the condition and get the most sun protection?that will help protect me from the sun and
