I've always admired Physicians Formula cosmetics. I like its approach towards makeup, especially the concealers and skin correctors. Other beauty companies address problematic skin with heavier coverage or thicker formulas, but PF takes the practical approach of color balancing. By this logic, if you have reddish skin, apply green. If you have bluish circles, apply yellow. Sure, it's not rocket science, but has the old color wheel ever failed you before?

Physicians Formula's latest concealer is the first of its kind -- a cover-up that conceals and treats dark circles with something called Haloxyl. So far, the coverage seems better than all of the drugstore products I've tried before, including an $18 concealer that wouldn't blend probably. At $6.95, you can't go wrong with this product.

Admittedly, it's difficult to figure out what shade you should use just based on the packaging, but that's a drawback of all drugstore makeup. However, if you roughly estimate that most people wear either Natural Light or Medium Beige, you have a good chance of finding the right color.

According to the company, the Circle Rx Circle Control Concealer can diminish dark circles by 70% by Week 2 and up to 90% by Week 4. A 90% reduction is a serious claim, my friends. Either way, I'll let you know how things look by the end of the month.
