I'm sick and tired of my body always building a keratin layer on top of my lips. I have tried chapstick,l-lysine and vitamin tablets, all sorts of lip balms, keeping them moist. immune system tablets but none has work for me. they only temporarily work. what i want is for my body to stop making keratin and for my lips to be completely healed. So the question i ask is this. How do i solve a 12 year old problem that i have with my lips? do i leave them alone? or do i keep reading forums to see if one day someone may have the actual cure for this.
