I had genital warts on the shaft of my penis and scrotum, I got cryo treatment and used Aldara cream to remove the warts. The treatments resulted in light colored/hypopigmented scars and redness. It's been over a year since the treatments and the scars and redness have not gone away, I've tried using over the counter scar cream but it's not had noticable results. Are there any treatments or products I can try that will get rid of the scars and redness? Fyi- I have tan/olive colored skin.
