Mac Prep+Prime skin review

I really dislike this product. I think is pretty useless.
It is white with little sparkle and a light texture.
I usually use medium/full coverage foundation, so the luminosity that it's suppose to give you, does nothing for me.
After I apply this primer the skin is a little bit silkier, but my Clinique dramatically different moisturizing gel does the same job.
It doesn't help with the foundation application and doesn't help it to last longer.
Doesn't hyde pores and doesn't help to reduce face oils.
I like the pump in the packaging but I don't like that I can't see when the product is running out.
I'll never repurchase this primer!
