Hypochlorous acid (HOCl) is the key ingredient in the spray — the same molecule white blood cells produce as part of the body’s natural immune response. The spray contains hypochlorous acid at 0.02% in a simple saline base, a fragrance-free mist for the face and body. The body produces HOCl naturally, which is part of why researchers have studied it across many tissue types. Clinical studies across dermatology, surgery, and ophthalmology have explored HOCl’s broad utility, with the majority reporting it useful in clinical settings across multiple tissue types (Haralović et al., Biomedicines, 2025). Sodium chloride and water are the only other ingredients in the formula, for a three-ingredient list made for dry, irritated, or redness-prone skin. In laboratory research, HOCl has been studied against biofilm-forming organisms. One study found HOCl disrupted Candida albicans biofilms in a wound model, a problem that conventional approaches struggle to address (Zmuda et al., Journal of Applied Microbiology, 2020). For everyday skin discomfort from razor burn, bug bites, chapping, or baby acne, the face mist soothes and comforts the look and feel of skin, and is made without parabens, phenoxyethanol, or drying alcohols. Safety data from a 157-patient aesthetic surgery cohort showed a surgical site infection rate of 1.27% when HOCl was used as a skin preparation agent, with both infections resolving with oral antibiotics (Arnaout et al., Aesthetic Plastic Surgery, 2026). Patch testing on the inner arm before first use remains standard guidance, particularly for those with sensitive skin. Related concerns:
