Hi. I would like advice on the skin on my lips. A month ago, when I went to bed, I did what this person is doing in this picture (I don't know how to describe it.) : http://farm1.static.flickr.com/21/38135119_dd100e9bc4.jpg?v=0 ; Just for no reason. I don't remember how long I did that for. I've done that before in different occasions and they've gone back to normal instantly. But the next morning, my lips didn't look or feel the same as how they used to be.
