Oh, Darcey, Darcey, Darcey Bussell:  how do we love thee...?  Let us count the ways. First of all, for your elegance.  And bravery:  not for all the tea in Stratford would we have careered down a wire into the Olympics closing ceremony.  Thirdly, we love you for having enough of a sense of humour to become a judge on Strictly this autumn.  (Forget about counting the ways:  we're counting the days.)

So with Darcey's star once again in the ascendant, The Sanctuary certainly lucked out with the timing of their announcement that she was the new face of their anti-ageing skincare.  That was a few months ago, and we've now had time to try the products - declaring this two-step mask our firm  favourite.

It's fun-to-use, too:  slather on the Peptide Transformation Serum, then a layer of the Thermal Rose Clay Mask.  We adore how this heats up on the skin, encouraging penetration of the skin-plumping hyaluronic acid.  Used regularly, it's said to reverse crêpiness - but what we'd also say is that it's great whenever skin's looking drab or dehydrated, in need of an urgent boost.

In fact, this duo will be doing a pas de deux on our bathroom shelves for some time to come.
