This week: Lynne checks out The hottest new Trend in skincare

When I heard about a new night cream that promises to compensate for the ageing effects of insomnia, I had it on my face quicker than you can say, “Oh God, did I remember to lock the back door?” Basically, I have the sort of brain that nudges me awake at 4am to pick over all the things I might have messed up that day (or ever, in fact), and in turn am rewarded with pasty, dry, knackered, grumpy skin in the morning. It’s not my imagination either; lack of sleep has been proven to accelerate ageing in all sorts of ways, whether it’s slowing DNA repair, reducing collagen production or wreaking havoc with the skin barrier.
