Achieve a perfected result from your foundation with Guerlain The Foundation Brush. A luxurious & sensorial gesture, The Foundation Brush is a tool optimised for the application of liquid foundation. Its unique 360° head brush offers express application with a natural finish, thanks to a dense & extremely soft tuft of pink hairs that pick up the perfect amount of product & distribute it evenly across the face. The Foundation Brush offers a uniform finish without streakiness, with an airbrushed, glowing finish. Apply a few drops of foundation to the face, then buff & blend it out.
