I have never been a lip primer person because I rarely wear any lipstick. Most of my lip products are super sheer, tinted balm types, barely there sort of things, in nude shades only. The only reason this caught my eye was because I saw "lush" and "water" and something just clicked on the subconscious level. Very glad I got it, have been really enjoying it so far. And what it does personally for me is 1) smooths and plumps the lips just every so slightly so whatever I put over it just looks better and 2) conceals my natural pigmentation, again, ever so slightly, which in my case is an added bonus because while I don't have very pigmented lips I do prefer they look just tiny bit lighter. Please don't let this last part turn you off, I really mean the concealing is just barely noticeable. I did see some reviews about how this makes people's lips ghostly looking and such. While each person will have different results I can tell you that compared to several other lip primers (I have randomly tested others in the store in the past, like Urban Decay's and Benefits both of which were like plaster on my lips!) this just adds a light veil over my lips. Other added bonuses - no tingling, minty sensations, SUPER light feeling, non-drying at all (while I would recommend topping this off at least with a balm, you could comfortably wear it on its own), satiny, non-matte finish, pleasant, barely there taste, very nice, light scent, little goes a long way (I just tap a tiny bit on top and bottom lips and smooth it with my ring finger). Just feels like a silky slip for my lips, really the best way I can describe it! « less
