In the past, I have used UV Naturals and Heiko Sunscreens. I found, when applied, they were greasy and left a caked-on white residue. Alba Botanica has been the best so far just stay away from the ones in their line with fragrance!
At the end of the day, limit your exposure to the sun by staying out of it when it's the strongest. If you must be out during those times, cover up with wide brim hats and other sun protective clothing. Also, don't forget about your lips!
