It has been said that it is a crime to not prime. It may not be officially listed as an illegal activity but once you start using a primer of any kind, you won't want to go without it. A primer's key purpose is to make your makeup, whether it be base or eye, stay in place for longer. They can also be skin smoothing, add a touch of radiance or even minimise pores. Primers can change the way your makeup looks and lasts on the skin so they're an essential part of many a makeup routine..

Bourjois Bronzing Primer ASOS seem to have taken this primer off their site so I'm hoping it gets added back because I love this. This primer was labeled as an alternative to the popular Chanel cream bronzer. I know some people like to use this as a cream contour as well. While it is way too dark for me to contour or bronze with, I like to apply a small amount of this after using a regular face primer. It gives your complexion a bit more warmth without leaving you looking orange. I have used this as a primer as well and liked it as one. 

Nars Smudge Proof Eyeshadow Base This is the best eyeshadow primer that I have tried. It has a wand applicator so you can apply this to your lids and then use your ring finger to gently pat it in. Apply eyeshadow as normal and it will stay put so much better. The primer really stops your eyeshadow from creasing. For extra longevity apply a cream base, like a Mac paint pot first.

Laura Mercier Radiance Primer If you're not so big on dewy finishes, a primer like this one can be the perfect way to make you look more awake. I typically prefer a more matte finish but applying this leaves your complexion with such a pretty natural glow. I've not tried any of Laura Mercier's other primers but this one has more of a cream, almost gel-like consistency. It's really easy to blend and again, your makeup will stay put with this underneath.
