These first appeared on counter a few months ago - but blink, and you'd have missed them: Clarins Instant Light Lip Comfort Oil sold out across the country almost immediately.

 Which tells you everything you need to know about this innovation, actually. (And take it from us: lip oils are 'the coming thing'.) With a 'doe-foot' soft applicator, sweep the nourishing oil onto lips. It's non-sticky, but very nourishing (and has a subtle sweet flavour).

Called 'Honey', the single shade features mirabelle oil (which just brings out the tone of your natural lips).

 We asked Clarins to let us know when the oil was back in stock - and it is - but we suggest you make it 'snappy': this has all the makings of a 'cult' product.
