I have this in three different shades; porcelain, classic ivory and the orange corrector.
I firstly purchased the classic ivory shade a while ago because of all the beauty gurus going on about how fabulous it was and this was the lightest shade at the time. This shade matches my skin tone so doesn't have much of a brightening effect.
I bought porcelain as soon as the shade was out as I love the consistency of this concealer and this shade is different great at highlighting.
I got the orange corrector because I heard it was great at covering dark under eye circles if you use a little bit.
The packaging of this concealer isn't exactly hygienic and I wouldn't recommend sharing this product with anyone. It is a squeezey tube with bristles at the end of it which allows you to distribute the product evenly under your eyes. The tube is also clear do you can see how much product is left and also what shade it is.
The formula is amazing it has good coverage, isn't too thick and is very easy to blend.
I definitely agree that this concealer is a must have and is such a great price.
I really like the yellow corrector pro concealer. It comes in a easy squeezable tube which I don't use straight on to my skin I squeeze it onto the back of my hand so I don't accidently squeeze too much out. I use this under my eye area and on acne scaring I have on my cheeks. The coverage of this for my skin is very good the colour matches really well and the cream consistency is really easy to work with, I find that it does crease abit under my eye and throughout the day as well but with a little touch up I am good to go. My favourite concealer to use at the moment!
