i've had this before.. you are in the early stages. I wish there was a way to tell people and prevent them from getting this. If your lips are inflammed, you really should look up something that can take care of inflammation. It will eventually spread to the whole of the lips.
No doubt it difficult... all treatments cost money to buy products.
btw, Vit A still has the skin growing.. it is thinner, but weak. Can be peeled off. I'll wait and see what happens.
