So what is its function in topical skincare? Some dermatologists use hypochlorous acid spray on the skin before and after a procedure that will disrupt the skin barrier — like an injection, laser, or peel — to lessen the chances of a wound, redness, or reaction. “In my medical clinic, I use it to prep the skin before injecting someone with Botox,” explains dermatologist Geeta Yadav, MD. She continues, “It’s shown to be much less irritating and equally as effective as chlorhexidine [an antiseptic], which is how we normally prep the skin before a procedure. Even post procedure, I find [hypochlorous acid] soothing on the skin, while still being cleansing.”
