Rich day creams

While it's not a treat in the sense that a whole chocolate mousse cake to oneself is a treat, or a day watching old 30 Rocks while pretending to your boss that you've got a dicky tummy after eating a whole gone-off chocolate mousse cake is a treat, rich day moisturisers are certainly on the treat spectrum. Origins's Youthtopia range (Ultra-rich Firming Cream, £45, johnlewis.com ) is perfect daily for dry skin and excellent twice a week for normal skin – or, if you've got the cash, Perricone MD's Nourishing Moisturiser (£60, perriconemd.co.uk ). It's like chucking a glass of water straight on to your face, but less drippy.
