I have a skin problem in the face that gets worse with the sun so I avoid it like the plague. I did some research and you need to apply the right amount of the right suncreen for the right period of time. Be sure you buy the best option you can find where you live, apply a lot, wait 30 minutes before going to the sun and reapply every 2 hours. Reddit (yeah) has a lot of good information.

>http://www.skincancer.org/prevention/sun-protection/clothingUsing the information from skincancer org you gonna see that a specific clothing for the sun has a protection factor of 80 for example. Jeans has something around 1000 (go throught the skin cancer site and you'll find). Buy some jeans and make a mask. it'll be much cheaper and much more protective. Just remember to pain some flowers or animals on it so nobody thinks you're from isis.
Also I don't know your age but the secret to look good in your 30-40-50's is avoid sun in your 20's.
