Lancome was a latecomer to the primer scene. Their MA maintained for ages that all you need under makeup is a good moisturizer and eye cream and color would stick and stay true all day. Those of us who've been using primers regularly would beg to differ, of course, and eventually Lancome released Aquatique Waterproof Eyecolour Base as an eye shadow primer.
One would think Lancome might have used the extra time for some serious R&D to develop a superior product. Well, in this case one is wrong. The texture of Aquatique is harder than most primers and almost waxy. It's spreads easier than I feared and creates the desired smooth canvas feel, but this kind of smoothness doesn't do much to make eye shadows stay in place. You feel like you're covering your lids with spackle but the color doesn't adhere to it very well. I've tried Aquatique base with numerous eye shadows from several brands, including Lancome, but the results were never as good as I get with other primers.
Bottom Line: They should stick with what they do best.
Lancome Aquatique Waterproof Eyecolour Base ($24.50) is available from most department stores, Sephora and lancome.com. I got the mini size as a part of a GWP.
