Following the news of her engagement to Prince William, Kate Middleton has become an international “it” girl. Gals around the world are emulating the future royal’s style, and have been clamoring to find out any and all of her beauty secrets.

Now, ladies who envy her creamy complexion are in luck, as an insider recently opened up about Middleton’s skincare regime. Julie Cichocki, Karin Herzog‘s U.K. managing director, told Style.com that the bride-to-be uses products by Karin Herzog, including the Professional Cleanser, Vita-A-Kombi 1, Vita-A-Kombi 3 Spot Zapper, and Oxygen Face Cream.

“Stress is the number one culprit for depleting oxygen in the skin, and, poor girl, what could be more stressful than an international announcement of a royal wedding?” Cichocki explained. “A wedding of any kind is stressful for a bride, and still, her skin looked just beautiful – dewy, plump, fresh.”

Middleton is not the only celeb to swear by Karin Herzog products. Earlier this month, Courtney Love spoke to the website about her love for the Swiss beauty brand.
