Blotting oily sunscreen skin: does this reduce SPF protection?
I have very oily skin that is prone to cystic acne, but I worry about skin cancer/aging, so I try my best to apply SPF when I know I’ll be in direct sunlight for 30 minutes or more.
After about an hour of applying SPF, my skin sweats and gets super oily, so I’ll blot it with tissues.
My question is: will blotting 30 mins-1hr after applying SPF have a big effect on my SPF protection?
