My 11 yo DD has an awful time with sunburn. She is fair skinned but only burns on her face! We have tried too many over the counter sunscreens to count. Her face burns up to her lower eyelashes. Does anyone know if there is any prescription sunscreen or OTC that works wonders? We've used lotions, sportsticks & etc. We are planning to go to the river for Labor Day & I REALLY don't want her to get burned! Your help would be greatly appreciated!
