Not narcotics or alcohol but MAKEUP BRUSHES!
A girl can never have enough!! My favorites are Marc Jacobs Beauty brushes, NARS Ito Japanese brushes, and Kevyn Aucoin. I’m surprised but I like affordable brands like Morphe and Real Techniques.. When you don’t have time to wash your brushes, I stock up on clearance or sale promotions of these and use them instead. With all those Facebook Turorial ads, I grabbed a set from Sigma too (good but pretty pricey) and use a variety from Sephora. Hourglass Ambient Palettes look different with the proper Hourglass Brushes. It! Cosmetics brushes work really well with their products. As someone with aging skin, I need a good brush that will buff out and remove excess dry skin looking makeup under the eyes and on the cheeks.
Use the upcoming Sephora Rouge sale to save on a these babies.Brushes May seem like a big expense but not all brushes are created equal. Your look will definitely be better enhanced with the proper tools. Your face deserves these investments.
