I received the sample of this months ago in my birchbox. Since I'm in my late twenties (scary!) and had many years of bad sun exposure, I'm on the hunt for a great product! This is one of few products where I saw instant results. In just a few weeks, I could already tell improved skin tone and more youthful glow. And the added bonus of SPF is great - but is still silky smooth and doesn't feel like you have a lof on your face. Even my friends noticed how great my skin looked! After the sample ran out, this was my first full-size purchase!
