KV has adult acne and we have luck with grooming care to a point.
I can tell when he is getting ill with infection because the acne will flare up before other signs like fever/O2 sats drop ect..
The only upside to the rare use of anti bio is the acne and oily skin dries up.
He uses topical antibiotics normally what we call the bingo dabber thing.
Hey Global. Try the ZNP soap and Acnomel for adult acne. It sure cured mine. I use the soap to wash my face every day, and I keep the cream on hand in case of a pimple flair up.
