This may be one of the weirdest beauty tips we’ve ever heard.

Margie Robbie, as well as being very talented, is one of the most stunning creatures we’ve ever seen and any tips she’s willing to share, we’re willing to try. Well, the actress has been sharing her secret trick to achieving the perfect pout and we have to admit, we’re a little hesitant. Margot says she swears by one product, and one product only when it comes to lip-balms and that’s Bepanthen Ointment. If you haven’t heard of it, Bepanthen Ointment is a nappy rash cream for babies – yep, one of the most gorgeous women in the world swears by nappy cream. The cream is also used by many breastfeeding mums to keep their nipples from getting chapped and sore. And why not a standard tub of Vaseline, you may ask? Well, the Australian actress has a theory about the products that claim to protect our lips and it’s that they don’t do that at all. “I have a conspiracy theory that lip balms actually have additives in them to dry your lips out so you keep buying them,” the 26-year-old told Elle. “But because Bepanthen is just a cream for dry skin, it works. I’ve used it my whole life.” Well, there you have it... stock up, ladies.
