Many of us will have beauty products that stand on bathroom shelves, unused because, despite the hype and the price, they really don’t do the trick. Birchbox, founded by Harvard Business School grads – and beauty fanatics – Hayley Barna and Katia Beauchamp, allows you to try out products before committing to full size. Sign up and you get five beauty and skincare samples a month, tailored to your profile, to try out over the next few weeks at home. We asked the girls to recommend their top, long lash mascara for the sultry summer nights that lie just around the corner.

1. Lord & Berry Alchimia High Performance Mascara. Great volume, natural curling and lengthening effects? Vitamin E and bamboo extracts to nourish and help regenerate lashes? What’s not to like about this long-lasting formula from make up atelier Lord & Berry? Plus, it’s water-resistant so you can splash about without a care. £13, www.birchbox.co.uk

Laura Mercier Long Lash Mascara

2. Laura Mercier Long Lash Mascara. Laura Mercier employs all its expertise to achieve longer lashes.  And it’s not simply the long-wearing, water-resistant and smudge-proof stretch formula that works the magic. The brush extends and separates lashes, distributing the formula just where it’s needecd. £19.50, www.birchbox.co.uk


3. Benefit They’re Real! Mascara. The UK’s number one selling mascara is just that for good reason. Lashes are left long and full, the formula won’t run or smudge and the colour – jet black – will make eyes pop. A unique definition-enhancing brush lifts and separates each and every lash, even tiny ones at the corners of your eyes. It’s so lush, it requires its own remover. £19.50, www.birchbox.co.uk
