Brushes come fat, fluffy, thin and wispy. They differ in shape and size and in texture, making it difficult to know which one is good for what. Synthetic hairs tend to be better for liquid and cream makeup. And natural hairs work best with powders (because pigments can stick to the fibers). We asked the pros how to achieve your best look with these uncommon gadgets. BUFF This fan brush is all about intricate detailing. “Pros use this to apply mascara to the base of the lash line and to dust away eye shadow fallout,” says Lijha Stewart, director of artistry and education at Make Up For Ever. DETAIL Use this multitasker with any major face product: foundation, concealer, blush or bronzer. The shape of the brush allows it to be used with all base cosmetics. Its flat side blends makeup over larger areas, and the pointed tip is best for precision application in the grooves. PERFECT Use this multitasker with any major face product: foundation, concealer, blush or bronzer.

Apply foundation to the face or conceal blemishes on the body with this one. LINE No, this is not a toothbrush. The thin fibers are terrific for creating lines. “Use the brush to line the lash line, to define eyebrows or to accentuate shadows in your lid crease,” says Artis founder Matthew Waitesmith.
