At Beauty City International we love to research and this month we sent our very own undercover agent, Natalia Oaks out to find out how clean are our Favourite cosmetic brands? You'll be surprised they're not as clean as you think, Natalia visited Boots Nottingham, House Of Fraser, John Lewis department store and Debenhams department store. Get involved, if you have a story you want us to investigate or share, email us [email protected]
