When you concentrate really hard, are you creating 11 lines? You know the lines between your eyebrows? Or, do you even know? Next time you work on a project that involves focused concentration, have a mirror handy and see if you indeed are creating 11 lines. Look how tense, unapproachable and the major 11 lines going on in the left photo! I'm more relaxed, approachable and no 11 lines! So pay attention to expressions that are adding unwanted lines to your beautiful face!
