I saw online that for a more natural look I had to use 2 shades if concealer. My real tone is Snow from Born This Way and I can use it under the eyes and for lighting parts of the face. Knowing this, what shade can I use to darken the necessary areas? like the sides of the nose of the cheekbones. Thanks a booty! Fair-clear skin with pink undertones, dry and very sensitive, intolerant to perfume.
