I am elderly and have had acne all of my life. I've noticed whenever my immune system is challenged, as when I get a vaccine for something or am coming down with a virus, that my acne just...disappears! Overnight, almost. Then, a couple of days later after a vaccine or getting over a bug, it creeps back to its original awfulness. Have y'all experienced this? Will immune boosters help? I've tried every prescription and OTC creme there is and my zits just laugh at the treatments and multiply. Thanks!
