I've used Malibu C Zinc C Wellness Serum on my skin for years. I have breakouts of shingles and it calms them down and they are gone in a matter of days instead of weeks. It has also helped immensely with the scarring. I love this product and I make sure I'm never out of it. I order six or more at a time. I also use it on my face, neck and chest. It is amazing.
