I think the Cyclosporine showed minimal improvement. My crusts stopped turning yellow and they were very thin. Also they would peel off every week as opposed to every 3-4 weeks, when leaving them alone.
And I was on it for 6 weeks.
Also you keep saying to let our lips crust up and go get a biopsy. But it wont make a difference whether they are built up or not. In fact it will be easier to get the biopsy if they are not.
Mine were built up when i got my biopsy and they had to cut through the crust and stuff.
