I have to admit it. I first saw this product on QVC. The hosts talked about this product as if it were the Taj Mahal of beauty products. Now don't get me wrong, it's a good product. Use it as a highlighter before and/or after your foundation or tinted moisturizer. You can wipe it on your cheek bones, or on the bridge of your nose, wherever you want a little extra sheen. The Magic Potion helps illuminate the skin.
But it's not a primer as the hosts on QVC mentioned. You want a primer? Stick with Laura Mercier's oil-free primer. Great product.
