Sorry i was kinda slow to get back to you
Personally, after this amount of time i would take it slow at first (a few hours a day and not in the heat of the day). If you find you can tolerate two hours in the sun, then you can gradually increase your time. Above all, i think you need to listen to your body. If you are starting to get red or if your skin starts getting that warm tingly burning feeling, its time to run for cover
. As for protection, i use something called "ocean potion" (my derm recomended it); i think its pretty good, its spf 30 so it provides alotta protection and its oil free, water and sweat resistant (all very important at the beach). And yes, i see no reason why not to put it on ur face...i almost always do. if you want to take even further precautions there is always protective wear (hats, visors, sunglasses, etc.). Hope this helps and don't forget to have fun!
