After receiving a sample from my last Ulta order, I am definitely hooked, even despite the high pricetag. I've only been using this for 4 days in the morning before applying makeup, and in the evening after washing/cleansing my face, and the fine lines around my mouth area are already starting to fade away. They are not completely gone yet, but so far this seems like a very promising product. And unlike other anti-aging products I've tried, this one hasn't made me break out at all. I'm really loving what I'm seeing so far. I'm only going to give this a 4/5 stars, because I don't know how the full-sized version of this product would work for me yet, but I do plan on buying the full size soon when the sample runs out.
