Get your pen and paper out if you want flawless skin like Girls' Generation's Yuri because she's revealed a skincare secret!

On the recent airing of 'Channel Girls' Generation', Yuri showed that drinking freshly squeezed lemon juice mixed with carbonated water for 5 days can greatly improve your skin. 

She named this concoction "beneficial-water", which actually is a play on words as it sounds like "Yuri water". Additionally, she added in a helpful tip, saying you should wait 30 minutes to brush your teeth after you drink this since the drink is acidic due to the lemon juice.
