I had HPV more than 5 years ago - I removed it by picking at it (I know, bad) and it eventually regressed and went away. I recently had a new outbreak, several months ago, and I realized it was soon after I started using a Benzoyl Peroxide body soap. I had the warts removed by a doctor this time, and everything was fine. I used the soap again and I noticed small papillomas. I had these removed before they could grow and have since stopped using the soap.
Could the soap be oxygenating my skin which helps the warts grow? I am almost convinced the soap triggered the new outbreak.
