This is a cheap eyelid primer, so you're getting what you paid for. It does basically do what it's supposed to, but I find that, for me, it doesn't absorb as well as other primers so if I'm not careful it can be visible.
I cant say that I've noticed less creasing from my eyeshadows. so I'm not totally impressed with this primer. Wasn't really expecting much from it because of the price, but I do admit that I use it from time to time when I cant find my other preferred primer and am in too much of a rush to find it.
While I have read so many great reviews for this product (both on here and elsewhere) when I tried it for myself, it just didn't work. I don't usually have sensitive skin but it irritated my eyelids so bad that they started developing raw, itchy and flaky skin which lasted for a month. I couldn't wear eyeshadow and had to get a topical cream from the chemist to try fix the mess - all in all, while this product may work for some it just caused more problems for me.
Tips: Be careful if you do have sensitive skin and stop using immediately if your eyelids begin to feel irritated, raw, flaky or rough.
