Usually a nude coloured eyeliner pencil is to make your eyes look bigger but, I already have quite big eyes, so I use mine to make them look brighter. The waterline of my eye is quite red and using a white eyeliner was always too obvious and fake looking, so I looked for ages to try and find a nude. I knew that MAC did one and Laura Mercier did, but I found it impossible to get my hands on them, they weren't online, and I couldn't find them at counters either. Then I found this Chanel one!
The colour is quite peach toned, so it works well for hiding dark and tired eyes, which is what I like to use it for. If I'm tired I tend to use it to brighten and make myself look more awake - and it works so well. Although, to be used as a corrector, it would have to be used on Fair-Medium skin tones - and I'm not sure a pale flesh tone is one you would use if you can a darker skin tone anyway. But I would highly recommend this if you are Fair-Medium as a corrector.
