Kate Middleton has been known to be one of the royals who have the most glowing skin. She also famed for doing her own makeup and seriously taking care of her skin. So, what is the future Queen of England's secret for her flawless complexion?

Harper's Bazaar revealed some of the beauty secrets and skincare products that the Duchess of Cambridge has been using to take care of her skin. One of which is an organic oil that is great in almost all skin problems.

It was revealed that Kate Middleton uses Trilogy Certified Organic Rosehip Oil when she is pregnant. The Duchess of Cambridge is said to be very cautious when it comes to beauty products and treatments but fell in love with this oil. The royal, reportedly, uses the rosehip oil to fight wrinkles and boost glow instead of harsher ingredients like retinoids.

According to Who What Wear, what makes Trilogy Certified Organic Rose Hip Oil great is its main ingredient. The product is made of the pure rosehip oil blend.

It brightens the skin and helps reduce the appearance of fine lines, wrinkles, and scars. Who What Wear also cited an independent clinical study that showed a significant reduction in the appearance of scars by 41 percent, stretch marks by 43 percent, and wrinkles by 23 percent. This makes this product a popular choice of moms and moms-to-be around the world.

The nourishing fatty acids and vitamins A and C in rosehip oil also boost the skin's moisture levels. The oil product also contains omega-3, omega-6, and omega-9, as well as antioxidants to help heal and protect the skin. It is a non-greasy oil product that makes it perfect for all skin types.

Kate is not the only one who is obsessed with this skincare product, other celebrities too. Apparently, the likes of Victoria Beckham and Cara Delevingne also use the product to keep their skin look amazing.

Well-renowned makeup artists are also using the products on their clients. According to Who What Wear, celebrity facialist Deborah Mitchell also uses the oil in their LIA therapy treatment. It is acupressure and healing facial treatment that both Kate and Beckham are also known to be fans of.

The Duchess of Cambridge's seal of approval makes it more appealing to skincare enthusiasts. The 20ml Trilogy Certified Organic Rosehip Oil is currently priced at $23.14 on Amazon, $25.99 at Priceline, and $20.30 at Look Fantastic.
