To answer your question, I'm will to go as far as it takes, I've already decided I will not be hurting my lips any further no matter what. That means I won't ever peel them again. As far as using natural products on them I would consider them in the future of course if my determination gives out on me, which I don't see happening for a long time :)
I personally believe keeping them moist all of the time might work faster than this method, however I would use natural things like aloe gel from the actual leaf and salt water from the ocean (what Jaye does and go swimming)...but I am going to continue with this method, hwoever I do plan on going in the water on my trip to the Grand Canyon this week :)
