This is my second bottle of this skin serum and I started purchasing Frownies over the summer. I didn't realize how much of a difference this skin serum made to my face! After my first bottle was gone (my niece was using it and I didn't know) I was hesitant about purchasing another because of the price and I didn't think it lasted very long, (again, because I found out my niece was using mine!), but it does! It only takes 3 squirts to cover my face and my neck (front and back). The smell is a little weird, but you get used to it. The glow and helpful 'uplift' (don't know what else to call it) to my skin is very, very nice, and I hope to continue purchasing in the future! If I could afford it, I would have this, as well as a couple other items from Frownies on subscription! I've had this serum a little over a month now, have used it every morning, sometimes at night, and it is still almost 3/4 full! Thank you!
