Time Out says
Fact: Covent Garden has more beauty shops per square metre than any other area in London. To celebrate this attractive asset, they're holding a beauty marathon, with special offers, masterclasses, instore tutorials, fragrance fittings and late openings from the shops around the piazza. Some shops will even be giving out free glasses of fizz and monogramed perfume bottles. It's a beauty fanatics delight. Find out more about the offers at participating stores here.
