CF have you peeled at all since you started with the melatonin?
Also I've almost given up on asking this question since it never gets answered but ill give it 1 more shot. If we now know that melatonin is working to help counter the overproduction of cortisol why wouldn't you fix the gland that produces cortisol?
YOu have agreed that the melatonin is only halting production of the skin, if you want normal lips without melatonin you need to fix the adrenal gland.
It seems so simple.. are you seeing things differently?
What are you planning on taking instead of melatonin to heal your lips, in my opinion the best option is to support the adrenal gland.
