I have tried city lips for about 3 months now and you're probably thinking 3 months that's an awful long time to continue to try a product well I kept an open mind and thought well maybe I just have to give it some time I never leave reviews that aren't good because I feel like everybody is pretty much to each his own we're all different however they make it so convincing and I finally caved and I bought this and I will be extremely honest with you it did absolutely nothing and if you notice the women that put this on already have pretty full lips so I don't know I will agree there's no stinging there's no weirdness as far as that is concerned but my lips do not look any different I even did just half my lips and left the other half empty with nothing on them and nothing again tried it for 3 months or it's a bed nothing no there's a reaction thank God but still I see nothing so I didn't end up returning it because of the hassle of what I've been through in the past of try it for so many days and easy refund and I didn't feel like doing that but I was really excited about this one and I don't see any difference I hate to leave a bad review I really do but I dont get it. It's just not working . Good luck.
