Kate Middleton’s fave beauty buy is sold every 20 seconds

This isn't the first time it's been rumoured that the Duchess of Cambridge is a huge fan of Trilogy's Rosehip Oil but we didn't realise just how popular the product is.

Rosehip oil has long been hailed as a skin saviour because of its repairing, nourishing properties and according to Refinery 29, one product is sold every twenty seconds. It's priced around the €37 mark and a number of studies have shown that the organic oil has been proven to reduce stretch marks, fine lines, scars and wrinkles. It has a minimum of 80% essential fatty acids (omega 3 and 6) and fatty acid (omega 9) content and a popular way to use the oil is by mixing a couple of drops in with your everyday moisturiser for a radiant glow. According to reviews, it helps lessen the redness associated with acne so overall, it's a multi-use product that ensures value for money. We may not be able to afford Kate's wardrobe but at least, we can imitate one step of her beauty routine and let's be honest, the Duchess has gorgeous skin.
