The one retinol serum that all the stars swear by

Retinoids (the umbrella term for retinol products) have become more than just a buzzword in the beauty industry. For the skincare savvy, they’re an essential, lauded not only for their exfoliating, smoothing properties but their youth-enhancing results, tackling everything from acne to pigmentation to fine lines in just a few drops.

The challenge for the consumer is finding the product that works for their skin – but according to a report from beauty site Byrdie, a group of A-list celebs might just have taken some of the guesswork out of the equation. How? Well, they all seem to swear by the same serum – and although it doesn’t come cheap, everyone from reality star to supermodel insists that it’s worth the investment.

The bottle in question is Resurface by Shani Darden – Retinol Reform, a product created by American aesthetician Shani, who is the go-to expert for names including Kim Kardashian, Chrissy Teigen and Jessica Alba.

‘A cult favorite all of Shani’s clients swear by, Retinol Reform is powerful, and effective at softening the signs of aging,’ her website explains. ‘Its unique formulation is stabilized at a low PH level to promote deeper exfoliation. Immediate results can be seen after just one night, while long term results get even better with continued use. You will wake up to smoother, more refined, and less congested looking skin every morning.’

‘It smooths out fine lines,’ Chrissy told InStyle of the serum previously. ‘Every time I use it, I get compliments on my skin the next morning.’

Jessica agrees: ‘I use Retinol Reform Serum every night and think it makes my pores and dark spots look smaller while also making my skin look all smooth and soft.’

Other fans of the product include Suki Waterhouse, January Jones and Rosie Huntington-Whitely, who calls it ‘her secret weapon to flawless skin’.

However, you don’t just have to take the glitterati’s word for it – on Shani’s website (which ships internationally, don’t you worry!), there are plenty of 5 star reviews from customers who’ve seen similarly incredible effects after using the product. Some say that it ‘turns back time’, and while others add that it’s ‘shockingly worth the price.’

‘I am officially on the bandwagon,’ wrote one. ‘This product is awesome in every way. The customer service of the company is wonderful and considering what you get, it is very well priced, it will be a staple in my skin care routine from here on out as it has improved my acne, fine lines, wrinkles, and pore size. So glad I tried it out!’
