Ive had EC for around 3 months and have been applying shea butter for about a month now.
What ive experienced is when people start applying moisture to there lips they think they are getting better which is true, but it depends how much you apply. In my case my lips looked better, but the peeling wasent reducing each time, it was pretty much the same. If you want to stop the peeling (not cure they will still peel if you stop), just apply anything which creates a barrier over your lips constantly through the day. Im doing it until i figure out what is causing my lips to peel so i dont have to walk around with scales on my lips.
