My lips have created a "scab" now (not the ec crust) where my skin is healing inwards. At the bottom of my bottom lip, there's already normal soft skin now and the "scab" is getting smaller everyday. Basically my lips are healing the same way a scab heals. When I get my lips wet, the "scab" doesn't turn white or become soft.
My ec is still cured but I think it will take at least another week before my lips are completely healed.
