Personally I don't suffer from Rosacea, but it's a common enough problem that I feel comfortable posting about it without first hand suffer-knowledge of the issue.
That patchy redness (mainly found on caucasion skintones) can make the search for correct foundation an ordeal. While the color looks right on your lower cheeks (most commonly where foundation color is gauged) and jawline; when the foundation is applied over the reddened T-zone and cheeks, the colors can turn anywhere from ashen to bright pink and that is a major problem!

Neutralizer can be used as a contour makeup as well. But use with caution! It may look like a light cream-colored foundation in the bottle, but when it hits the skin it is definitely a greeny-yellowy liquid. It's not meant to be used on it's own unless your skin is so fair that you can get away with it.
Bottom line: if you suffer or know someone who battles with rosacea, the LORAC Oil-Free Neutralizer is worth a try. You can get your hands on it at Ulta and Sephora and see for yourself. You can also order it online at LORAC Cosmetics, Sephora, Ulta, and of course Amazon.com. The retail price is $30 US but the .90fl oz bottle lasts a long time. One pump is almost always too much. Little goes a long way with this one!
