Anthelios. Expensive, but I work outside. has halted sun damage for me.
PP, which one? I'm a NP, I work outside too, and I have found personally that the 15 SPf anthelios is "not quite enough" (bc it's ... only 15), whereas the 40 SPF Anthelios does do the job of blocking sun for someone who works outdoors, BUT, it also leaves me ghosty face since it gets that extra SPF from titanium dioxide.
(and the 60 SPF ones by La Roche Posay are not recommended by EWG due to their ingredient list).
