Lip balm is, of course, a handbag essential for an on-the-go boost of hydration and a wash of pretty, sheer colour and one fated day at Wimbledon in 2019, we got a rare glimpse at Catherine, Princess of Wales' go-to formula.
While this wasn't the first time we've been let in on one of her beauty bag essentials (Jo Malone's Orange Blossom cologne is widely rumoured to be Princess Kate's perfume of choice), it definitely sticks in our mind as a very iconic moment. After all, it's not every day a royal gets snapped with a product, in hand, or one so easily recognisable as Clarins' Lip Perfector. As for the shade in question, it's thought to have been 01 Rose Shimmer, which, as the name suggests, offers a soft wash of rose-pink tint to the lips, along with a hydrating shine.
