That being said, it may help keep odor at bay. "Glycolic acid is thought to help reduce body odor by reducing the pH of the skin and making it harder for the odor-causing bacteria to survive," Garshick says
"The current trend using alpha hydroxy acids in deodorants is a fabulous new way to fight body odor," says board-certified dermatologist Michele Green, MD, who is based in New York City.
Body odor is created with the interaction of sweat and normal skin bacteria,” says board-certified dermatologist Dr. Elyse Love. “Glycolic acid will not decrease sweating, but it does alter the skin’s pH, which potentially decreases the concentration of skin bacteria in the area. Less bacteria means less odor.”
