We heart Benefit's brow services. (Jo would probably disappear into the background if hers weren't regularly – and expertly – dyed by Benefit's brow experts). The launch of a new 'beauty loyalty app', then, is good news for all those who – like us – swear by their great brow-grooming skills.

You can use it to find your nearest Benefit brow counter, and book on-line. And there are some great – um – benefits, too, when you remember to flash your app in-store, notching up loyalty points. Here's what you'll get (one treatment – one 'stamp'):

• Two stamps = complimentary brow tint worth £11.50

• Four stamps = complimentary makeup lesson

• Six stamps = complimentary lip wax worth £9.50

• Eight stamps = complimentary chin wax worth £9.50

• 12 stamps – a free Gimme Brow, the UK's top-selling prestige brow product (and another Benefit must-have, for us).

The app's completely free – and you can find it here on the iTunes Store and here on Google Play for Android phones

You'll never go un-tweezed – or in Jo's case, untinted – again...
