I never wore an eye shadow primer before, and I normally buy different brands of one product to finally find the one or ones that are really “wow”. But in the case of Too Faced Shadow Insurance Anti-Crease Eye Shadow primer I won’t buy any other eye shadow primer, cause it is enough to have just it – simply the best eye shadow primer ever; Ok, you can think “how can she say that, if she didn’t compare with any other?”, but I don’t want to compare, cause it is really excellent. It does what it promises; totally worth the money and I’d repurchase this product again!
