It’s no secret that the Duchess of Cambridge has flawless skin. The 35-year-old mother of three manages to look radiant despite juggling whatever royal life throws at her, so one wonders: what’s her secret? Well, it’s no secret actually, Kate reportedly has a single natural marvel to thank for her complexion: rosehip oil.

Word on the ground has it that Duchess Kate’s pick of the bunch is Trilogy Rosehip Oil, a New Zealand creation that has helped her to maintain flawless skin throughout all three pregnancies. Trilogy’s formula contains 80 percent fatty acids, is completely organic and what do you know? We stock it here.

But back to rosehip oil, the matter at hand. Dermatologists and chemists say it’s a skincare superhero and supermodels and royals credit it for their glowing skin, but what exactly is rosehip oil, and what makes it such a beauty essential? Rosehip oil – otherwise known as rosehip seed oil – is a pure plant oil commonly used in skincare that has been valued since ancient times for its many healing properties. This makes it especially helpful for those with sensitive skin, and it also punches well above its weight when it comes to its hydrating and anti-aging benefits.

Contrary to popular belief, rosehip oil isn’t actually derived from roses but the rosehips from wild-growing rosehip bushes. The beautiful golden oil is extracted from the rosehip seeds and sent to work its magic on all manner of skin issues. It is deeply nourishing and moisturising (hello, dry skin people!), but also superfine with balancing properties, making it ideal for those with normal or oily skin, too. And because pure, cold-pressed and organic rosehip seed oil has no added preservatives, chemicals or fragrances, it’s especially great for sensitive skin types. In fact, it has been proven to effectively calm inflammation thanks to the fact that it is rich in vitamin E and anthocyanin (two ingredients that soothe), making it hugely beneficial for those dealing with rosacea, eczema, and other inflammatory skin issues.

Next up, not only do the fatty acids and Vitamin A in rosehip oil moisturise the skin, but they also promote skin regeneration and can improve skin flexibility and permeability. This means that rosehip oil products can improve skin texture and even reduce the appearance of acne scars or stretch marks if they are problems that may be troubling you.

So, how about adding some rosehip to your day? While rosehip oil can be used all-over, it can also be specifically formulated for the face. Trilogy’s Rosehip Oil Antioxidant+ contains the unique antioxidant complex Rosapene, which helps to boost skin condition to achieve greater radiance. The rich seed oil blend delivers intensive nourishment, replenishes softness, and improves elasticity while providing daily antioxidant protection for radiantly healthy skin.

If you’re looking for a cleanser, Trilogy’s certified natural Rosehip Transformation Cleansing Oil is a beautiful to use, silky emulsifying formula that effortlessly removes all traces of make-up and grime, and is formulated with Certified Organic Rosehip Oil, sweet almond and papaya oils. The pure plant cleansing oil transforms from oil to milk when mixed with water to thoroughly cleanse without stripping moisture and is very gentle around the eyes.
