First Off - Too Faced Shadow Insurance
Eye shadow primer is probably the most important step in your eye makeup routine. It will keep your colour bright and bold and in place all day. I've only have sampled Too Faced Shadow Insurance but one application doesn't always give you a real idea of how the product works and how you react to it. So I was excited to get to try it properly.
That said... I hate it. It irritates my eyes and then they water and my makeup gets wiped away. I recently applied eyeshadow and it did not retain any of the colour. This might not be the fault of the primer, but it was not something I had noticed with my other primer. When it isn't irritating my eyes, it does keep my shadow in place. It doesn't crease. It just bothers my eyes. Otherwise it's good.
I know that this is one of the biggest seller of eyeshadow primer, and I am going to keep giving it a chance. But I think I would use it when I fill my brows in different colours, instead of on my eyelids.
