Known for its ability to heal wounds and eliminate harmful bacteria, this powerful ingredient effectively targets acne, rosacea, and more. Its disinfecting capabilities are reported to be 100 times more potent than bleach, according to Rachel Lee Lozina, licensed esthetician and founder of Blue Water Spa. We consulted with top board-certified dermatologists and an esthetician to explore everything you need to know about hypochlorous acid, its advantages, and how to integrate it into your skincare routine.
What Exactly Is Hypochlorous Acid?
Hypochlorous acid is a versatile ingredient. "Hypochlorous acid naturally occurs in the body, particularly in white blood cells, where it helps defend against foreign invaders and bacteria. Composed of hydrogen, oxygen, and chloride, it offers both antimicrobial and anti-inflammatory properties," says Dr. Marisa Garshick, MD, FAAD, a board-certified dermatologist. Its anti-inflammatory and antibacterial effects are particularly useful for skin conditions like acne, folliculitis, eczema, and more.
A popular reason many people incorporate hypochlorous acid into their skincare routine is its effectiveness in treating acne. "It’s quickly becoming a hero in the fight against acne in the skincare world," shares Lozina.
Hypochlorous Acid Benefits
This trending ingredient addresses a variety of skincare concerns, with wound healing being one of its standout benefits. It helps heal several skin issues and reduce bacteria on the skin. "By eliminating the organisms that trigger inflammation and disrupt the skin barrier, it promotes healing. It’s a safe and gentle option for treating wounds and skin conditions like eczema," explains Azadeh Shirazi, MD, a board-certified dermatologist.
For those struggling with breakouts, hypochlorous acid works by breaking down and inhibiting the growth of acne-causing bacteria. When applied to acne, it kills the bacteria, preventing the survival of harmful organisms, says Lozina. Beyond treating active breakouts, it also eliminates harmful bacteria around the affected area, helping to stop the spread of acne.
How to Incorporate Hypochlorous Acid into Your Routine
Integrating hypochlorous acid into your skincare routine is a breeze. Typically available in spray form, it’s easy to apply. "It’s most effective when applied after cleansing, before any serums or moisturizers, and can even be used midday over makeup or after a workout," says Dr. Garshick. Additionally, it can act as a convenient facial cleanser for those on the go. If you’re pressed for time post-workout, just spray hypochlorous acid to refresh your skin and combat harmful bacteria.
This ingredient is particularly helpful during the colder winter months, as it helps counteract the stress that cold weather puts on the skin. (Think healthier skin barriers, calmer skin, and less irritation.) Since hypochlorous acid is mild and non-irritating, it’s generally safe for regular use, according to Dr. Garshick.
Potential Side Effects of Hypochlorous Acid
“As with any skincare product, some individuals may have adverse reactions to hypochlorous acid. Reported side effects include dryness, irritation, and itching,” shares Lozina. It’s important to avoid overusing hypochlorous acid, especially when combined with exfoliating products or other potent skincare ingredients.
Bottom line: When used correctly, hypochlorous acid is well-tolerated with minimal side effects, according to Dr. Garshick. "However, be mindful of overusing this ingredient, especially when combined with other toners or antibacterial products," warns Dr. Shirazi. It’s best to stick with gentle cleansers and skincare products while incorporating hypochlorous acid into your routine.
