I've invested in the MAC 187 (hooray for me!) Now I have a problem. My foundation Clinique Acne Solutions seems a tad thick and it's hard to stipple it on my face. Sure, I can stipple then swirl, but what's the point? I wouldnt have invested in a stippling brush if I had to swirl it to use it... How can I make my foundation more runny? What other hypoallergenic brands have good liquid foundation?
