La Petite Robe Noire by Guerlain has created the first 2-in-1 brow mascara and highlighter: Brow Duo. This latest addition is an ultra-practical product that can be carried wherever you go for perfect brows at all times. On one side, the brow mascara allows you to define, set in place and create visibly fuller brows. Incredibly easy to apply, transform your look in the blink of an eye with a few brush strokes! Its 8-hour long-hold gel formula withstands even the most eventful of days. On the other, a highlighter with a creamy formula creates bigger, brighter eyes. For a natural result, use the mascara, brushing your brows to define their shape. Repeat this step to build up the thickness of your brows. Then apply the highlighter under the arch of the eyebrows for bigger, brighter eyes. For an even more intense and luminous effect, contour above the arch of the eyebrows with the highlighter.Made in Italy.
