I am a long time Clinique user and was finally introduced to this product about 5 years ago. Let's just say it is a life saver. Even in the summers when the weather is super dry too. I put it on and it immediately makes my skin feel smooth and healthy. It's like a drink for my skin! Applying makeup is easier when I use this and I really cannot go a day without it. What are your skin/makeup must haves? Please do share!
