Nah! Not worth it! I don't usually use face primers, but i finally gave in, the girl at sephora talked my into it... and i used it one night, before going out, to test it's resistance and overall performance. I fouund my regular La roche Possay moisturizer does a better job at prepping my skin for my foundation. I should mention I use Mufe Hd foundation... which I love. I found that this primer caked up my skin. I took away from that beautiful finish the foundation gives me. It looked and felt heavy and didn't find that my make up lasted particularly well through the night.
I won't repurchase, in fact I won't be using it again.

Amazing primer.
The HD Microperfecting Primer comes in several different colours. Each colour is for a certain skin issue. I have the neutral one. The website explains the function of each colour.
Of course, primer is used so make up will last longer and go on smoother. I bought this primer to match the HD foundation because they work better together. It also makes my skin feel really soft and supple.
