First, let me say that I have tried everything to get rid of my PPP. For whatever reason I developed about 100 small papules all over my glans and corona during puberty. I've tried retinols, and every extreme skin treatment you can buy and nothing got rid of them except the PPP KIT. I have done 3 sessions and zapped about 50 of them so far. I wanted to wait a while before giving a review to see how things healed. For me, the healing process took about 15-20 days and all the spots I treated are healed now and free from any issues. For me, starting at a lower power level didn't work. I would have to get the needle too close and it would stick to skin. As soon as I went up to power level 5-6 things worked much better for me. An arc would form a good distance away from the skin and I could move it around a little to zap the papules. The Kit is quality and came with everything I needed. I am very pleased with the results and would recommend the unit.
