A tinted sunscreen.
It was really nice. However, it has a strong tint to it and feels like Makeup with sunscreen. Nice, but uninexpected.

Love!
It’s a little runny but honestly doesn’t bother me at all. Gives me a good glow with a little coverage! Better than any expensive ones I’ve used & layers well with or without makeup. Just wish it was a higher spf but definitely buying again.
