What is Kate Middleton's favourite mascara?

According to HELLO!, the Duchess of Cambridge's favours none other than Lancôme's Hypnôse Mascara, a strong contender for the best mascara for length and volume with a die-hard legion of fans.

Available in both black and brown shades, this best mascara buy promises to create fuller looking lashes without clumping (our pet peeve).

The unique PowerFull brush also helps to separate your lashes while applying for proper definition and length.

The publication reports that Catherine also loves the brand's Artliner liquid eyeliner, which comes with a pen-like foam nib for precise application.
