keratosis
"This was well worth doing. I initially did my face and a year later am back doing my scalp to finish the process - should have done it all at once. It completely removed all brown spots and left my skin looking 15 years younger. It took three weeks before my skin started "smoldering" but it wasn't more painful than a sunburn. Looked very red and I worked from home for about a week. This worked beyond my dermatologist's and my best case scenario. Awesome!"
