I hear you! I don't like heavy coverage and nothing else covers my redness all day. This foundation has been amazing for me, although the colour I'm using (Calming Ivory - 03) could be a tiny bit yellower on me. I use a pea sized amount mixed with a bit less of Studio Moisture Tint to warm and sheer it a bit and it lasts all day. The Clinique foundation alone has better coverage but it's a bit heavier/more formal than I like for day wear. It's a bit like Matchmaster that way. If I want a more formal look that will hold up all day, I use it alone. Google the review before and after pics - I'm nowhere near as red as some of those who've provided pics, but you can see what a huge difference it can make.
