I bought this to try as I'd never found a concealer thick enough to cover my undereye circles. What surprised me about this was the consistency of the product. I found it really thick and creamy and a little went a long way. It lasted all day without any creasing. I used the Mac prep and prime and Estée Lauder double wear foundation and all products worked well together to get that flawless finish.
I used it to highlight also and it worked great. Just to add some definition around the Cupid's bow.
Great product, will be repurchasing when I run out!
I really like that Mac has a wide range of colours and undertones so you always find a shade that suits your skin tone. I hate the packaging, the pump always pumps out too much and i feel like i waste quite a lot. I don't like that it's glass because I feel like it'll break really easily. It's good as an eyeshadow primer and doesn't crease on my eyelid but I find that it creases under my eyes. It's a good full coverage concealer, it's thick but doesn't look cakey
Tips: Apply with fingers under the eyes to warm up the product
