One issue brought up by exercising more AND getting obsessed with skin care AND using ingredients that increase sun sensitivity is that I have to think a bit more about how I’m going to coordinate my exercise with my skin care routine.
For me, the easiest so far has been to exercise after work. At this point, the sun is setting (or already set if I’m getting started late), so there is minimal sun exposure, and I still have the remnants of my daily sunscreen on. By the time I’m done, the sun is basically set (if I didn’t start in the dark!), so it doesn’t matter if I’ve sweated off the remainder of my sunscreen and I can just do my usual wash routine in the shower and then go right into my nightly product(s). If it were any earlier in the evening and/or if the sun was more up, it would probably make sense to reapply the sunscreen before going running. And since it isn’t UNGODLY HOT anymore, I’m not sweating as badly either.
When it was hotter, I was liberally applying my go-to US sunscreen: Coppertone for Kids/Babies Tear Free. It’s hella water/sweat proof, and if some days I double-cleansed twice a day, so be it.
