We've said it before.  And we'll probably say it again.  (And again.) When it comes to mood-shifting, no oils have the power of Aromatherapy Associates to lift us up or waft us off to the land of Nod. (Fact:  Beauty Bible's No. 1 Desert Island Must-Have is Deep Relax Bath & Shower Oil.) Their treatments, of course, are widely available - but our favourite AA 'branch' (as it were) has now become a renowned mecca for the stressed-out:  a flagship store and treatment destination in Knightsbridge.

Upstairs, you'll find the whole range of oils, skincare and bodycare, beautifully showcased.  You can experience mini-treatments, or learn by smelling the essential oils in their 'raw' form.But downstairs, heaven truly beckons:  boutique-hotel-style treatment rooms where you can enjoy facials or body treatments.

The ultimate luxury, meanwhile, is this:  for £450, you can have a personalised oil blend created by AA's founder Geraldine Howard, which will be dispatched in an engraved botttle, and can be replenished with your customised oil at any time.

What's ours?  We've called it 'Even Deeper Relax'.  We didn't think it was possible (and nor did Geraldine!), but it does just what it says on the (gold-lettered) bottle.

Cue sound of gentle snoring, from the Beauty Bible office...
