I get what you're saying...but this is something I've been inflicting on myself since I was a kid...about 15 years ago I started using chapstick all of the time. So if you think about it that way it's not just a normal wound, it's been a consistent wound only getting worse over time. It seems very logical to think that a wound of this magnitude would take several months to heal. Even a broken bone can take 4 to 6 months to heal, and that's just from one impact, think if you were constantly breaking your bone in the same place for 15 years, it would take a lot longer than the normal 4-6 months to heal. I know it's a bad comparison because bones aren't the same thing as skin, but you get my idea.
And I've been having progress since the beginning...Just because the scabs didn't look better doesn't mean the skin underneath wasn't getting better...like I've said a million times over you need to focus on the skin after it peels. Of course the scabs will always look horrible. Each week though the skin underneath has shown more improvement compared to the peeling cycle before it. However in the last few weeks the crusts haven't been building up as much so it seems like they are healing better than they were before, when in reality they are still healing at the same rate as they have always been.
