Same Problem here....
I switched sun screen. Now using Swox. 50
Super sticky, stays on all day.
Actually happy with it!
I always use a large base Cap.
Started using sunglasses.
There is one guy on the hydrofoil Pro tour with always some cloth covering the entire face. His new solution with absolute no skin visible looks super good. Maybe someone knows who he is, so I could contact him.
BTW. After two „dislocated rips“ I started wearing an impact Vest....
I guess I look like an absolute „donkey“ on beach
