I've just finished applying my steroid and objectively it hasn't changed much my condition. I'm still continuing to not cause any trauma while applying moisturizer but yes, there is still a peeling, of course without this weird crusted build up, but still annoying and will be until having normal lips.
At one point, I tell myself I have to live with it and hope that one day, gradually, it will go away. I've wasted so much time, but it's clearly difficult to have normalish life with this crap!
PS : Honestly I wouldn't care applying moisturizer all the time if the real matter, which is chronic peeling, disappears. By the way this habituation is debatable. I've for a long time now applied product on my lips and the non-affected area is still perfect.
