If you have dry, flaky lips, you absolutely MUST buy a lip sleeping mask.

I used to have a bad habit of picking at the dead skin on my lips with my teeth all year round, so they were always bleeding and a mess. But then I bought a Lip Sleeping Mask from Olive Young, applied a really thick layer every night before going to sleep, and I truly saw the light! Haha. When I gently rub my lips while washing my face the next morning, the old dead skin peels off like dirt, leaving them super taut and soft like a baby's bottom! It doesn't cake even when I wear matte lipstick, so I plan to keep using this forever. Haha.
