No tiara needed.

There is no denying that the royal ladies always manage to look picture-perfect. From the late Queen Elizabeth to Catherine, the Princess of Wales and Princesses Eugenie and Beatrice, these ladies always look glowing. And yes, we know they have the funds to pay for the best makeup artists there are and can afford skincare regimes most of us can only dream of, however, did you know that the royals also have some pretty affordable beauty favourites? It's true. Behind the palace gates, here are the beauty buys that insiders have revealed have the royal stamp of approval: Essie Ballet Slipper nail polish Known for her dislike of bright nail polish, the late Queen Elizabeth was all about light, pretty pastels when it came to her manicures. Her perfect polish? Essie’s ‘Ballet Slippers’, which has been her go-to for over 30 years, ever since 1989, when the Queen’s hairdresser wrote a letter to brand founder Essie Weingarten, specifically requesting a bottle of the pink-nude polish for Her Majesty. It is even rumoured that Princess Beatrice wore it on her wedding day a couple of years ago – making this the ultimate royal polish pick. Trilogy Rosehip Oil When it comes to the Princess of Wales, rumour has it that Kate's glowing skin is down to her favourite beauty bargain – Trilogy's Rosehip Oil. "Kate continues to use rosehip oil in her daily skincare regimen," an anonymous source told US Weekly in 2015. "She loves the effect it has on her skin."
