This is my 3rd bottle. I use it every day, sometimes twice a day. Great for a finishing step or under moisturizer. I love the smell and light consistency, it gives a nice matte finish, not sticky. My only qualm is the bottle - every one I've gotten squirts and gotta on my counter, etc.
I've used this serum for a year and I can't go without it! It's better than the $50 serums I have used in the past.
