Will waterproof mascara ruin lashes?

NO, NOT necessarily. Traditionally, the ingredients used to make mascara waterproof have made the products more drying, which can make lashes brittle. One trick is to add a layer of waterproof mascara on top of your regular formula, which protects your lashes but still helps to prevent smudges. Alternatively, buy a newer waterproof formulation which does away with the downsides. One bargain buy that stands out is Revlon’s Volumazing Waterproof Mascara (£8.99, boots.com or superdrug.
