Yes, you read that correctly: grey. Unpromising a colour, grey, isn’t it? Especially when it comes to cosmetics. But I had been told by a fellow beauty journalist that it was brilliant, so despite my reservations, I scooped out some grey cream and put it on my skin.

That day, three people I see regularly and who therefore know how my skin usually looks asked me what I’d done to achieve such glow. The only change was the addition of that grey cream, so I decided to do a sneaky little experiment and use it twice a week to see if the praise flooded in on those days. It did and I am now a convert.

The only problem? The grey cream is La Prairie’s Platinum Rare Haute-Rejuvenation Cream , and it sells at £1395 for 50ml, making it the most expensive thing I’ve ever put on my skin. The lofty cost made and indeed makes me hesitant to recommend it; it didn’t escape me that the price is prohibitive for all but a few and had I not been sent it as a gift by the brand, it would be out of my reach. Besides, I’d always lambasted very expensive skincare on the grounds that no high street products are actually able to penetrate the skin, the best they can do is work on the outer dead layer, and try to make it strong and glowy.

My favourite serum is the Mortar and Milk PHA Barrier Repair .
