Q: What's the difference between tinted moisturizer and foundation?
A: Technology has evolved to the point where there is not a lot of difference between a tinted moisturizer and a foundation. In the past, a foundation allowed you to better build coverage level. However, now with the advent of BB/CC/DD creams, most tinted moisturizers are great foundations. I personally love and use Laura Mercier's SPF 20 Tinted Foundation in Nude.
