I have three other different eye primers and I must say this is my favorite. My eyeshadow last all day and night with this bh cosmetics primer, my eyeshadow doesn't crease at all when I apply this.
I really do love this product. Through sweat and tears it does not budge. I use it as a shadow primer and it's the best primer I've ever used. This is a must have for any artist especially those working with brides. It helps the shadows show up more vibrant and truly lasts all day. I love it!
