It's simply amazing. I first used the Tone Up and loved it so much that I decided to try this one next, and I was able to purchase it at a time when it came with a ton of freebies. This is most effective when traveling, where I want to minimize my luggage, so I keep it in my contact lens case and bring it with me. Even if I go to hot springs several times during my trip, I can just quickly put this on and it moisturizes and protects from the sun, and if I need to put on makeup afterwards, the primer effect allows me to put it on quickly, so it's really helpful. I'm thinking about trying all the different types, but new colors? new products? renewed versions keep coming out one after another, and I feel like I can't keep up.
