We'd all love to know the secret behind Kate Middleton's perfect complexion, and apparently it's not just the pregnancy glow, she also has a little help from Trilogy's Rosehip Oil.
Kate reportedly started using the oil during her first pregnancy, and a bottle is now said to be sold every 20 seconds.
Containing 80% essential fatty acids, the wonder product nourishes and repairs, promising to "help hydrate skin and reduce inflammation". It can be used on your face and body to minimises the appearance of stretch marks, fine lines, scars and wrinkles.
As part of your skincare routine, a few drops can be applied underneath your makeup in the morning and before bed after cleansing.
Its versatility and gorgeous scent earns its holy grail status, which would explain why it's also a favourite of Miranda Kerr and Victoria Beckham.
If it's got the royal seal of approval then we're stocking up!
