Works! Transformed my skin! Recommend!

I never write reviews but I'm going out of my way to make an exception with this one, it's FABULOUS! My face tends to look and feel oily by the end of the day and with this product it never does anymore! It's amazing. I have and use three products from this brand, the primer, the moisturizer, and this one. I cannot recommend them enough, they've transformed my skin. I wear less makeup, look better, and feel better. My face feels dewy and fresh. I wish I could give them 6 stars.

The best stuff EVER.

I can’t explain what a difference this made on my face. I’m 55 and my skin looks amazing every time I use it. And after 30 days, my it seems to have made a permanent difference. I can’t imagine my facial routine without it.
