There's no evidence OTC antibacterial soaps prevent disease more than washing with plain soap and water. Some antibacterial drugs can do more harm than good.
This aligns with what I've always been told. The mechanical action of thoroughly washing your hands for 20 seconds + the surfactant in the soap is enough to allow the subsequent rinse and dry to physically remove shit from your hands.
Same with your pits and junk. Just a normal bar of unscented soap is all you need to not be stinky and prevent bacterial growth particularly during the summer. Unless you have special needs based on skin conditions or gland conditions of course.
Do I need Ritual of Oudh body scrub after my Summer Rain shower gel and afterwards before going out some Serendipity parfume? Fuck No! Does it help me feel good and I frankly got enough negativity in my life already and need some positive feelings? Yeah!
