I'm someone who really swells up easily, but after getting double eyelid surgery and drinking coconut water for a few days, the swelling went down quickly. ㅎㅎ Those who got the surgery, even if it doesn't taste good, definitely try it. It's delicious and worth drinking because it tastes good. ㅋㅋㅋㅋ Stock up on it when it's on sale at Olive Young.
