Emma Watson is obsessed with lipstick.

The 'Harry Potter' actress used to hate wearing colour on her lips but now enjoys experimenting with different shades.

She said: ''When I was younger, I hated the idea of wearing lipstick. Then, in the past two to three years, I've been wearing lots of different colours - my favourite daytime shade is coral.''

Emma is also a big fan of brightening her look with nail colour, though she admits the effects never last very long for her.

She said: ''Nails are fun now too. I rarely wear colour on my hands though because I always ruin it within a day, but seeing it on my toes in the shower makes me happy.''

The 22-year-old star takes the time to exfoliate her lips for smooth colour application and has figured out the best ways to make her lipstick last.

She told Glamour magazine: ''To get a really intense look, blot off the first layer and reapply your colour. Use nude lipliner to get the perfect cupid's bow and exfoliate your lips with a toothbrush. They'll look great.''
