It's summertime, baby! I can't wait to go to the beach and swim in the water!
Yes! I actually just bought some sunscreen and a swimsuit, so I am ready to go swimming at the beach or a pool. 
What SPF sunscreen do you use? Those UV rays can be dangerous!
I try to get at least 30 SPF level, Coppertone or even Neutrogena has been effective for me. How about you?
30 SPF??? You jokin me? I use at least 70 SPF because I don't want to get cancer.
30 SPF as a minimum for just regular wear, for the beach or poolside I've purchased like 50 SPF. I also try to use sun hats when I can.
Yea, staying indoors is the best physical sunscreen, as they say. More time for hobbies that don't get you all sweaty and gross, ya know?
The key really is reapplying the sunscreen after a few hours, but most of us don't ever really do that. That's why I also like those spray versions out now, very convenient.
It's crazy how you can get burned from the sun's rays. Like, you don't even have to get heated by the rays, they will just negatively interact with organic molecules.
That's true. That's why I usually prefer mineral sunscreen to the chemical versions, but the chemical sunscreens are readily available everywhere and do not give you a white filmy cast. 
Ohhh mineral sunscreens? I haven't heard of them. Probably because the USFDA hasn't approved new active sunscreen ingredients IN ALMOST 20 YEARS!
