Grab a tub of it while you can.

A €32 anti-wrinkle cream sold at Marks & Spencer has beauty buffs filling their carts, after fans started showing off the results of a week’s use online.

One PRAI AGELESS Throat & Décolletage Crème is snapped up every 60 seconds at the swish supermarket, with users showing off the impressive results on beauty blogs all over the world.

The luxurious, cruelty-free crème, developed specifically for the throat and décolletage of women aged over 45, is said to attack and fix “crepiness, double chins, droopy jowls and turkey neck” in seven days.

Key ingredients are retinol and hyaluronic acid.

Blogger and author Suzi Grant, based in Brighton in the UK, posted a ‘before and after’ shot on her website Alternative Ageing when she used the formula after a two-week sun holiday.

Commenting on the results on Facebook, she said: “No, the lighting is not different, there is no editing, and if you zoom into my lip wrinkles and spot on my nose, you’ll see that there is no difference between the two photos – apart from my chest and throat!”

In the comments on the M&S website, another fan reports: “After using this cream for two weeks I noticed a definite difference to the skin on my neck which had started to look ‘crepey’. I’m 60 and thought this was something which I had to live with so I covered it up as much as possible but after two weeks of using this cream it has tightened considerably.”
