Katie Thomas is the Senior Beauty Editor at Marie Claire UK. With over 10 years of experience on women's luxury lifestyle titles, she covers everything from the best beauty looks from the red carpet and stand out trends from the catwalk, to colonic irrigation and to the best mascaras on the market.
Originally from Wiltshire, she spent much of her childhood in Germany and Switzerland learning to ski, but failing the language. She went to Bournemouth University, where she studied Multi-Media Journalism.
She started her career on fashion desks across the industry - from The Telegraph to Brides - but found her calling in the Tatler beauty department. From there she moved to Instyle, before joining the Marie Claire digital team in 2018. Since then she has spearheaded the beauty content across the site. She aims to inject a little bit of joy into every piece that she writes and would hate for anyone to think she takes herself too seriously.
She’s made it her own personal mission to find the best concealer in the world to cover her tenacious dark circles. She’s obsessed with skincare that makes her skin bouncy and glowy, low-maintenance hair that doesn’t require brushing and a cracking good manicure. Oh and she wears more jewellery than the Queen.
Her favourite part of the job is recommending products that she knows her friends, family and readers will love and benefit from using. As she always says, 'the best foundation is a bloody good skincare routine.
