And what we love most about her new product fave? It was a recommendation by a fellow celebrity – you see, they pass on beauty secrets too!
Stephanie posted this picture (above) to the social media site on Wednesday (25 November), along with the revelation that actress Susie Amy, who's best known for her role as Chardonnay Lane-Pascoe in ITV's Footballers' Wives had recommended it to her...
"Ah my secret weapon has just arrived...thank you @susieamy, this is the bomb!" the Made in Chelsea star wrote.
Susie is actually an ambassador for ARK Skincare and counts this serum as one of her all-time, beauty musts.
"I absolutely love the Radiance Serum," she reckons. "It gives my skin the most gorgeous glow all day."
Now Stephanie has added ARK Radiance SkinResponse Serum, £42, arkskincare.com to her skincare arsenal, which also includes Trilogy Certified Organic Rosehip Oil, £26.50, johnlewis.com; Australian Bodycare Anytime Balm, £13.50, klmbeauty.co.uk and St Tropez, boots.com.
The anti-ageing, illuminating serum is perfect for glow-getters, and essential for this time of year when your skin takes a bit of a battering from burning the candle at both ends.
And we'll be keeping a beady eye on Stephanie's skin over the next few weeks for proof!
If you fancy ensuring your complexion is impossibly glowy for the party season, but can't quite afford to get your hands on this serum, pop it on your Christmas wish list and try Botanics All Bright Radiance Concentrate Serum, £3.49, boots.com in the meantime.
