Very easy to apply and feels light on my oily/combination skin type. It also doesn't make my foundation look cakey (like some other sunscreens do).

The only downside is that if I apply it above the eye area, it eventually (while I'm out and about) will run down into my eyes, and start to sting and hurt like h*ll. Maybe the formula is too runny? Otherwise it's a great product.
