This unique Lancôme dual-end brush features synthetic and natural bristles for easy application of foundations, creams, and liquids. Custom dome-shape brush allows you to customize coverage by fitting the contours of the face. Use the large end of the brush for bigger areas and the smaller end for targeting imperfections. Application Technique: Begin application using the large end of the brush with short, feather-like strokes. To build coverage, press the domed-end of the brush into areas that need correction. For more sheer coverage, apply with a soft, swirling motion. Use the smaller end of the brush to get precision correction using the tip to apply product or the side to blend.
