Glycolic acid has been suggested as a deodorant option to address underarm hyperpigmentation. Let’s break it down:⁠ 🔸 Lowering pH and bacteria: Glycolic acid claims to lower the pH of the underarm area, creating an inhospitable environment for odor-causing bacteria.⁠ 🔸 Uncertain effectiveness: The effectiveness of glycolic acid as a deodorant is not well-established or widely studied, leaving its actual impact on odor control uncertain.⁠ 🔸 Potential skin irritation: Glycolic acid is known to be a potent exfoliant and may cause skin irritation, sensitivity, or even exacerbate hyperpigmentation in some individuals.⁠ 💡 Consider safer options: Instead of relying solely on glycolic acid, there are safer alternatives available for managing underarm odor such as benzoyl peroxide. ⁠ ⁠ #dermatologistadvice ⁠
