Just ok

"First time trying this product. I love the toning mist, so I was interested in trying other products. The good: does not cause breakouts, no strong smell, nice texture, pump is good. The not so good: I didn’t find it very hydrating, unfortunately. It was thin and just didn’t really feel like it did anything when applied. I think it would be great for oily skin, but for my dry/combo skin, it just doesn’t quite cut it."
