The 23-year-old actress has an impressive collection of a range of beauty products, reported Contactmusic.
"What's quite funny is that I have tonnes of products at home. I've always loved make-up and I'm fascinated by how much it can transform people. But I don't actually wear much of it. It's so ironic - but I just love products," Watson said.
However, there are three must-haves that always find a place in Watson's handbag.
"I'm English and I have fair skin, so I love blusher! When I travel, I always have a moisturising cream with me on the plane and I like to carry fragrance with me too," she added.
