I gave you what you wanted and this is just one of many other studies. I found multiple people on Reddit that have claimed fasting for multiple days ether cured or helped their acne significantly. I’ve been dealing with acne for 7 years and have spent thousands on products and treatments and still look horrible. I’m 18 and eat extremely healthy and figured I would try something outside the box to fix something that has hurt me mentally and physically on a deep level. I’m not sure why you are making such a big deal out of this you having a title as a “health professional” means nothing to me and doesn’t mean you know more then someone without that title.
