Overall, good c:
Throughout the summertime, I went running everyday, wearing nothing but layers and layers of this sunscreen. I was a bit concerned, because I'm ridiculously acne-prone, and the combination of sweat, open pores, and a product on my face worried me. For three whole months of just wearing this, I didn't break out one bit.
This is the only sunscreen I can handle, because it really is lightweight. You can feel it on your skin, but it's not like a deadweight, that you're constantly aware of.
