If you think Kate Middleton's flawless skin is down to expensive royal treatments, think again.
The secret to her glowing complexion is reportedly an organic serum from Germany, according to a rep from the brand.
Biotulin Supreme Skin Gel, usually $157.68, contains spilanthol, a local anaesthetic extracted from the paracress plant.
This can rapidly relax muscles in the same way that Botox does, creating a noticeable reduction in fine lines.
It also contains hyaluronic acid and other plant extracts to hydrate the skin, so it's plump and firm.
Kate is reportedly so much of a fan that she's recommended it to other high-profile women, including sister-in-law Meghan Markle.
Other users rave about it too.
"I really noticed an improvement of the wrinkles on my face," says one user.
"Terrific," adds another.
