Today marks the official start of Christmas, which also means the start of advent calendar opening season. If you've left it too late to pick up a beauty advent calendar – because we all know the good ones mostly sold out back in October – then fear not because John Lewis is here to treat you to gifts at no cost to yourself.

The retailer has launched a '12 Treats of Christmas' digital advent calendar for My John Lewis members, which allows app users to get a daily treat from the 1st-12th December when they unlock virtual doors.Today's deal might also be the most enticing for beauty lovers as it gifts them a free mini Charlotte Tilbury Pillow Talk Push-Up Lashes (usually £26 here full-size).

To claim the mascara, simply download the John Lewis app and create an account, if you don't already have one.Then, head to the 12 Treats of Christmas section to input your details before the digital advent calendar pops up on your screen.To redeem this particular gift, you need to head to your nearest store and click the 'use in store' button when you go up to the counter.

Once you've hit the claim button you have 12 hours to pick up the sample, so don't hit the button until you're ready. You also only have a limited time to open each of the 12 doors, so we'd advise acting swiftly to reap the rewards.
