Arriving in an electric blue hue, the Yves Saint Laurent Lash Clash Mascara brushes on an ultra-pigmented coat of colour while visibly curling, lengthening and adding volume for up to 24 hours. n Featuring iris extract, the formula nourishes the lashes with wear, promoting a fuller look over time while instantly lifting and defining. A large double-conical brush deposits more formula meaning fewer strokes are needed for high-impact results, as it sweeps through the lashes to encourage a wide-eyed, fanned-out effect. Build your lash look as desired for more intensity while the bold blue tone grants a vibrant, eye-catching edge.
