Well, I have been using City Lips for a couple of weeks now and while I love it as a lip gloss and moisturizer for my lips, I really haven't noticed any real plumping effects. I do use it before bed and under my lipstick/gloss as well or by itself. I am not sure if I would order it again yet though for the price. I will give it more time and make my decision after I am done with the tube of it.
Bottom Line: No, I would not recommend this to a friend
