oh never! it's so gentle and weightless on the skin. if your skin is sensitive, Careblend is very non-invasive. In fact, sometimes skin can get an even oilier reaction out of frequent use of products that are intentionally drying, as a counter-reaction to feeling dry. My best advice is to try a light application of it during the time of the month when your skin feels the most strong and stable, just in case, but it's very easy on the skin overall, and very finely milled. it's my favorite powder in years, since I couldn't get my old standby Shu Uemura loose powder so easily anymore, plus it looks awesome in photos and is very age-defying.
