When it comes to skincare, we practically have an array of face creams, lotions, serums and moisturisers lining our bedside cabinets at this point. And while theres so much emphasis on our faces, one area that we often neglect? The neck and chest - one of the most overlooked areas of our skincare routines.

　　The skin in this area is thinner, more delicate and more prone to the visible signs of sun damage, pigmentation and fine lines. So, youd think wed take just as much care with our décolletage as we do with our faces, but thats not always the case.

　　However, those who use This Works Perfect Cleavage Neck Serum are already one step ahead. And, the internets favourite serum, which launched back in 2023, has already sold out multiple times since. Supposedly, one bottle of the stuff sells every four minutes. Pretty impressive, right?

　　One fan of the award-winning product even went as far to say, its like a neck lift in a bottle!, while another commenter revealed, I must say I was sceptical about this, but its definitely made a difference.

　　The best thing? Previously £40, you can currently snap it up for just £27 in the Amazon Spring Sale.
