Skincare has a manner of taking the physique’s personal biology, bottling it, and promoting it again to us. Hypochlorous acid (HOCl) is the newest instance. It’s a weak acid that your white blood cells naturally produce to battle an infection and kill micro organism. Now it’s being spritzed throughout morning and nighttime routines as an all-around pores and skin repair.
However HOCl isn’t new. Hospitals have been utilizing artificial variations for many years as a disinfectant. In reality, the lab-made kind dates again to 1834 and was utilized in each World Wars. So whereas #SkinTok makes it sound like a cutting-edge discovery, dermatologists have recognized its potential for a very long time.
Right here’s what it’s, the way it works, and what dermatologists need you to know earlier than including it to your skincare routine.

Hypochlorous Acid, Clarified
Chemically, HOCl is a weak acid and a potent oxidant. The physique produces it throughout an immune response, nevertheless it may also be synthesized in a lab by working an electrical present by saltwater. This artificial model was first developed in 1834, used as a disinfectant throughout each World Wars, and has lengthy been employed in hospitals for wound care and even in veterinary medication.
Not like harsher disinfectants like bleach, HOCl is biodegradable, unhazardous, and freed from noxious fumes. Truly, analysis reveals it might kill sure micro organism quicker than bleach. In skincare, it’s bottled at ultra-low, stabilized concentrations. “Consider it as your pores and skin’s built-in protection mechanism, bottled,” writes Dr. Mollie Kelly Tufman, molecular biologist and founding father of the Magnificence Lab.
Why It’s In Skincare
Dermatologists have used HOCl for many years to forestall an infection, hold wounds clear, and scale back scarring. Early analysis suggests potential in treating pimples vulgaris, seborrheic dermatitis, and tumor suppression. Extra not too long ago, it’s popped up as topical sprays and mists, promising to calm breakouts and soothe redness.
Its attraction comes from its antimicrobial and anti inflammatory properties. HOCl neutralizes acne-causing micro organism and different microorganisms that set off flare-ups. “In comparison with niacinamide, which works regularly to control oil and assist your barrier, HOCl is extra of a primary responder,” writes Tufman. “It reveals up quick, calms issues down, and makes restoration simpler for irritated or breakout-prone pores and skin.”
“Benzoyl peroxide additionally has antimicrobial results, however it may be much more drying and worsening, so it might result in rashes or dermatitis,” says board-certified dermatologist Gloria Lin, MD. HOCl, against this, is light sufficient for delicate pores and skin and secure for situations like eczema, psoriasis, or rosacea. Plus, not like benzoyl peroxide, it gained’t bleach your garments or towels.

Some folks spritz it underneath their arms or on their ft for a fast refresh (although it gained’t substitute deodorant). In eye care, HOCl is used to assist with dry eyes, styes, and situations like blepharitis and meibomian gland dysfunction (MGD). It will possibly additionally scale back microbial buildup across the lashes and eyelids.
The Caveats
There are limits. As a result of it’s an oxidizer, it might intrude with substances like vitamin C and different antioxidants. If each are in your routine, dermatologists recommend spacing them out (vitamin C within the morning, HOCl at night time). Lin additionally says extremely acidic exfoliants like sturdy AHAs can disrupt HOCl’s pH.
Stability is one other concern. HOCl breaks down when uncovered to gentle, warmth, or poor packaging, so most merchandise are available in opaque bottles with stabilizers. Retailer in a cool spot. Don’t pour it into a distinct container; the molecule degrades as soon as transferred.
