What Is Hypochlorous Acid?
Hypochlorous acid is a multi-purpose skin care ingredient that can help reduce harmful substances, like bacteria, on skin that can go on to cause redness and breakouts. It also has anti-fungal and germicidal properties that make it an interesting option for reducing common pathogens on skin and surfaces.\n\nThe body naturally makes hypochlorous acid, where it serves as part of a fierce system of defense against harmful microorganisms that can cause illness and infection. It’s for this reason that hypochlorous acid is often tapped as a disinfectant in medical settings.\n\nWhen applied to skin, in-vitro and in-vivo studies demonstrate that hypochlorous acid can help promote a smooth texture, reduce the appearance of breakouts, soothe irritated and reddened skin, help reduce the health impact of various illness-causing pathogens, and help assist in skin recovery. Promising studies show that hypochlorous acid, when used in a superoxidized solution, might be on par with the breakout-busting ingredient benzoyl peroxide, but more research needs to be completed before boldly making that claim.\n\nThis ingredient is highly sensitive to pH levels and overall product formula stability. Formulas that contain hypochlorous acid should have a pH between 3.5-5.5. The hypochlorous acid used in skin care formulas is synthetically created.\n\nIt’s an active component of bleach, however it is not harmful to skin (remember, our body naturally makes it). Your nose may make this association since hypochlorous acid’s scent is reminiscent of bleach, albeit not as intense.
