This is one of the two shades that work well as a neutral base for fair/light skintones. It has yellow undertones, so it's good for very pale people, however because of how light it is it is probably the best base for showing the true colour pigment of a shadow - it's lighter than most skintones and therefore evens out and lightens the background colour that a shadow is then applied to. Painterly is the other base for fair/light skintones, which is actually going to be nearer most of these skintones because of the pink undertones, so if you are looking for something to even out lid colour that can be worn on its own, that's probably going to be a better option. See the full Painterly review here.
As a base, paint pots are excellent. Unlike primers like UDPP, they are thicker and have a slightly tacky finish that powder and even frost shadows will cling to. If applied properly they are very unlikely to crease, even if worn all day long (though this will, of course, depend at least in part on the quality and consistency of the shadow/pigment worn on top of them). They are thick enough to even out skintone with one layer, but can also be layered if necessary. You need so little at a time that one pot will last a very long time, even if used daily.
Product quality: 5/5
Worth the price? No doubt about it. Given the quality of the product and how little is needed per use, it is a very good investment.
