keratosis
"I used Zyclara for 2 months, applying it for a week and then taking a week off. I have to say, it does work. I had many pre-cancer spots on my forehead, face and shoulders, that stayed there for years, despite annual freezing treatments. Zyclara cleared up these spots, and they seem to be gone permanently. 



As for side effects, it was a terrible experience, but only for the first couple of weeks. Basically, the first week of treatment was Hell, the second week was Heck, and the third and fourth weeks were Gosh and Golly. So, only the first week of treatment was painful.  



For that first week of treatment, it was like being hit with both a body-aching flu and a sleeping sickness at the same time."
