My daughter received this free for review and she gave me a 'chunk' to try...I'm hooked! It's so crazy expensive but it I can see that it would last 4-5 months, then I would be ok with it. So far, the 'chunk' was about 1/2 big, I've used it twice and I can see there is barely any used! I use a beauty blender sponge. It has such good coverage, I use less concealer...and believe me, my under eye circles and hyper pigmentation is dark!
