Why is a foundation with a yellow undertone usually best ?

Most skin types have yellow undertones with true red undertones being extremely rare. Skin colour almost always has a yellow undertone since that is what the natural colour of melanin (the pigment that gives your skin its natural colour ) tends to be. As a result , yellow -based foundations look more natural on most skin types ; from fair complexions to the darkest coloured skin. Pink or orange maybe be great for your cheeks and lips , but it doesn't make for the most natural- looking face. Remember , foundation is not to be used to change your face ; it should blend into your skin , making your other make-up appear more natural.
