Remember the foundation with a waiting list of 25,000, now there's a face cream causing mass hysteria among beauty fans world over.

There are currently 7,500 people on the waiting list for Marks & Spencer Absolute Sleep Cream (€30) which was first launched last year. According to Harper's Bazaar, it sold out everywhere and is soon to be restocked but with so many people mad to get their mitts on it, you won't see it for dust. The hero product was created by an in-house development team at M&S who came up with a night cream that's designed to make your skin "look like you've had eight hours sleep even when you haven't". The formula, which is released over the course of a night's sleep, contains a couple of stand-out ingredients including niacinamide, a must for brightening dark spots, and vitamin E, an oldie but a goodie for skin health. There's research to back this up too with a paragraph on the website explaining that the cream was independently tested on 104 women with 71 percent declaring that their skin felt "transformed" within two weeks. Impressive stuff, now we just wait for this wonder cream to reappear on the M&S website...*refreshes page*
