What is Hypochlorous Acid?

Hypochlorous acid (HOCl) is a naturally occurring molecule that white blood cells produce to fight microbes and reduce inflammation. In ophthalmology, purified HOCl sprays are used safely on the eyelids and lashes to cleanse without stinging or disrupting the tear film.

Because HOCl mirrors a substance naturally made by the immune system, it is highly biocompatible. Peer-reviewed studies support its role as a well-tolerated option for periocular hygiene in real-world eye care settings.

Unlike alcohol-based removers or soapy cleansers that strip oils and irritate the ocular surface, HOCl is non-irritating while still effectively lowering eyelid bacterial load.

Board-certified ophthalmologist Diane Hilal-Campo, MD integrates HOCl into eyelid care plans to help prevent makeup and environment-related irritation as part of her practice’s safety-first approach.

HOCl’s antimicrobial action combined with its soothing qualities helps reduce eyelid redness and supports recovery from minor irritations as part of comprehensive eye care.

    Benefits for Eye Health

Benefits for Eye Health

Adding hypochlorous acid to a daily routine can be especially helpful for makeup wearers, contact lens users, and patients with dry eye or blepharitis, providing cleaner lids, fewer flare-ups, and more consistent comfort.

Studies show HOCl significantly reduces bacterial load on eyelids, addressing a key factor in styes (infected oil glands) and chronic inflammation like blepharitis.

By limiting bacterial buildup and debris at the lid margin, HOCl helps protect oil gland function, easing scratchy, irritated symptoms in patients with dry eye disease.

HOCl supports eye-safe beauty habits by sanitizing lids and lashes after makeup removal, lowering the risk of bacteria that can accumulate in products like liquid liners and mascaras over time.

Because HOCl is gentle, preservative-light, and non-stinging, it can soothe sensitive eyelid skin and reduce triggers of redness or itching when used consistently.

Consistent HOCl use can help lower bacterial transfer to the lashes during higher-risk times such as heavy makeup wear or travel, supporting eyelid comfort.

    How to Use It Daily

How to Use It Daily

Hypochlorous acid is quick and easy to use; consistent, gentle application provides the best results.

Spray over closed eyelids and lashes twice daily and let air-dry, or apply to a cotton pad and gently sweep along the lash line to cleanse margins without rubbing.

First remove makeup with a gentle cleanser, then apply HOCl to sanitize lids and lashes and reduce residual bacteria after cleaning.

Using HOCl before inserting and after removing contact lenses can help keep lids cleaner and reduce the chance of bacterial transfer to lenses or eyes.

During periods of irritation, heavy makeup use, or travel, increasing HOCl use temporarily can help maintain lid hygiene and comfort.

Choosing a Quality HOCl Spray

Selecting a product designed specifically for eyelid hygiene ensures safety, stability, and effectiveness in daily eye care routines.

Look for formulas created for eyelid care that contain minimal ingredients (water, sodium chloride, hypochlorous acid) and no added fragrance or harsh preservatives.

Choose products from reputable eye care brands or practices that prioritize stability, so the antimicrobial effect remains consistent over time.

At her Oakland practice, Dr. Hilal-Campo recommends only trusted HOCl sprays that meet safety standards for sensitive eyes, ensuring reliable patient results.
