I had ingrown hair after waxing, and since I already had a prescription for retin-a, decided to apply some to my armpit to help exfoliate. After a few days I realized that it also controlled BO. I'm wondering why this works... does the exfoliation just reduce the breeding grounds for bacteria, or is something else happening?
Thank you for sharing. That is very interesting. I was not aware that retinoids could also have an effect on odor production in the underarm. Retinoids are a class of drugs related to vitamin A and have been found effective in acne, psoriasis, wrinkles, dark spots, etc. How it exactly works in the underarm remains unclear – but the cell renewal and overall skin barrier improvement might be helpful in this. Very interesting overall! Thanks for sharing, Chris.
