i am convinced that leaving them alone is the ONLY cure! the more you exfoliative them the more trauma you are causing to them hence they will not heal!, lets say you get a scratch on your arm, after a while a thick skin is formed and then it just comes off by itself if you keep taking off the hard skin without it being fully healed the hard skin will keep forming therefore it becomes a cycle, our lips i believe work the same way! what do you guys think? when i leave my lips alone the hard skin just comes off naturally byitself in the shower
