I agree with a lot of the other reviewers... this highlighter is out of this world gorgeous. It's like actually having that glowy, celestial type of skin without any sort of obvious "makeup" effect. Even my most natural, skin colored highlighters don't quite compare when I'm wanting a completely natural, "bare" skin type of look. I love highlighters with an extreme passion and this is up there among the best I've ever worn. It melts into skin beautifully and makes it looks naturally lit from within, sort of the way skin looks when it's freshly washed, exfoliated, and moisturized. That baby soft, dewy appearance. It's colorless with super fine, sparse shimmer throughout. I use clean fingers to apply and smooth in since I love really working it into skin so it looks very natural and seamless. It looks beautiful in photos, and when I wear it I seem to get complimented on my skin a lot. The texture is silky, lightweight, thin, and ever so slightly tacky so it helps it stay put where needed and doesn't start smearing or transferring everywhere. I apply in all the usual highligher types of areas (tops of cheekbones, nose bridge, cupid's bow) but also use it often over cream blush to add a little glow.
The contour is on the warm side for my slightly cool toned NW5-10 skin, though I don't think it pulls orange or ruddy on me at all. But a little goes a very long way so I have to use a light touch with this. I use it under my cheekbones for an easy, effortless bit of contour. When it's done right it just adds a little bit of recession and a shadowy effect. When I first started using it I kept applying too much and it looked obvious. The right brush really makes a difference. I use the Chanel Foundation Brush #6 to apply and quickly blend, then a softer stippling style brush (MUFE 122 Blending Brush) to smooth it out and really blend everything in well. I don't love this, but I do like it. I only use it once in awhile since my go-to contour is Chanel's Notorious. And besides that I don't contour all that often. The texture is the same as the highlighter, so it's easy to apply and blend, and works well with skin's natural texture. The color is a medium, warm toned brown with a slight coppery tone. I find I use it more in the summer and warmer months when I use powder bronzers more often, so it looks more natural overall.
For reference my skin is sensitive and reactive but I haven't experienced any issues with this irritating my skin at all. Also, I have highlighted blond hair and light hazel eyes if that helps.
There's a ton of product here so it's lasted me well over a year so far, and I use the highlighter all the time and there's still about 75% of that product left in the pan. Depending on how much and how often you use it I imagine you'd get a lot of mileage out of this. Still, I wish they'd sell the two products separately as I'd keep buying the highlighter in a hot second and I doubt I'd repurchase the contour. So that leaves me on the fence as to whether I'd repurchase this again when I run out. Hopefully by then TF will have decided to package these separately, but if not I'm leaning towards a repurchase simply because the highlighter is so great.
So overall I'm giving this a three due to the difficult to use color of the contour and the amount of times I use it. But keep in mind the highlighter deserves five lippies.
