I got sunburned today which sucks, I was too lazy to carry a sunscreen to reapply, or a parasol and went from rehearsal to a picnic without thinking. I’ve been on a retinoid for 6 months already so it’s probably not that. If you are buying or have bought a typical parasol this summer, like the ones found in East Asia, remember that the silver-lined ones around SPF30 (from the packaging) and the black-lined ones are SPF50+.
The black ones have higher UVA ratings as well. I have a heavy black-lined one that sucks to carry in my bag, but may become necessary as we get closer to solstice.
