Kate Middleton was spotted holding a $26 lip gloss

Kate Middleton is known for her iconic sense of royal style, but very little is officially known about the Duchess of Cambridge’s beauty routine.

That’s why it came as a pleasant surprise when Middleton was spotted at Wimbledon on Tuesday holding a tube of what appears to be her current go-to brand of lip gloss.

The duchess was photographed pulling out a tube of Clarins Instant Light Natural Lip Perfector, which costs $26 but was sold out on the Clarins website on Friday. It appears she opted for a subtle pale-pink shade called Rose Shimmer.

The gloss contains shea butter and mango extract and what the brand describes as “a delicate vanilla scent.” It has 4 1/2 stars on Ulta Beauty’s site, with positive reviews calling it “great for a ‘no make-up’ look.”

It’s quite possible the Queen is also a fan of the product, as Clarins is one of the few beauty brands she’s given a Royal Warrant of Appointment, described as “a mark of recognition of those who have supplied goods or services to the Households of HM The Queen, HRH The Duke of Edinburgh or HRH The Prince of Wales for at least five years, and who have an ongoing trading arrangement.”

The warrant allows the brand to display the royal coat of arms, making it the closest the royal family gets to doing official product endorsements.

The Rose Shimmer shade was sold out online at most major retailers on Friday, proving that the “Kate effect” is still in full force.
