Callas Cosmetics is a French Company that has cosmetics designed in Japan and France, but made in Korea. I gave a bunch of their products a try and was quite impressed.
Callas Light Up Makeup Base is a rather interesting item because it can work both as a foundation or as a primer. The Callas base provides moisture and UV skin protection and is available in a couple of color correcting shades, plus in the shade Milk, which is a light natural tint. The base feels great and when used as a primer, works quite well as a base for further makeup.
But the milk shade of the base also gives decent light coverage–similar to a sheer tinted moisturizer. So while it can be worn as a primer, I found that it also was perfect alone for some moisturizing, sheer coverage. My favorite use has been as a foundation on my upper face, and as a base for mineral makeup on my lower face where I have some redness and pigmentation.
I linked to the order page from Amazon.com, but I actually ordered mine from Yesstyle, which is my favorite Japanese and Korean fashion, beauty, and accessories site. You can also view Callas items at Callas.com.
