M.A.C Studio Fix Fluid SPF 15 was put to the ultimate test of seeing how long it wears and, not surprisingly, the formula lasts for a full 24 hours. A travel-sized version of the modern matte, liquid foundation combines medium-to-full buildable coverage with broad spectrum SPF 15 protection. Applies, builds and blends easily and evenly while controlling shine with a non-caking, breathable formula that does not cause acne. Comfortable and extremely long-wearing, it helps minimize the appearance of pores, giving skin a smoother and more even look and finish.
