Princess Kate looked positively radiant at her annual Christmas carol service on Dec. 6. So much, in fact, that it led many to wonder whether her glow was the work of twinkling lights overhead or something less obvious—like a secret skincare ritual, perhaps.
The beauty routines of the royal family are famously enshrouded in mystery. In 2019, when a British plastic surgeon alleged the Princess of Wales "loves of a bit of baby Botox," the Palace was quick to release a pithy statement calling the rumors "categorically not true." "The Royal Family never endorse commercial activity," the statement reportedly added. Just about everything we know with regard to Princess Kate's favorite beauty products comes from an indirect source. In 2020, for instance, Michelle Obama's makeup artist revealed the former First Lady had been using a line-smoothing Biotulin cream "regularly on the recommendation of Kate Middleton." But parsing the kind of beauty products and treatments she likes is basically impossible, unless you read between the lines.
