This Spray Is What Will Calm Your Skin Down

There’s a new trend making waves, and it’s more than just another viral sensation. Fitness enthusiasts, beauty lovers, and brides-to-be are packing spray bottles of hypochlorous acid alongside their deodorants and towels, claiming this powerful ingredient can prevent post-workout acne, clean gym equipment, kill bacteria on flights, and even reduce odour.

But with wedding season in full swing, could hypochlorous acid be the ultimate skin saviour for brides in the run-up to the big day—or a handy beauty must-have for serial wedding attendees? Let’s break it down and uncover the science behind this potent yet gentle compound.

What is hypochlorous acid?

Hypochlorous acid (HOCl) may sound intimidating, but it's actually a natural part of our immune system. It’s a weak acid produced by white blood cells to help fight off bacteria, viruses, and inflammation. According to Dr. Madhuri Agarwal, a dermatologist, "Hypochlorous acid is an integral part of our immune system and is present in white blood cells. It’s a weak acid that has antibacterial and anti-inflammatory actions."

Essentially, hypochlorous acid works as the body’s natural defence against harmful invaders, making it an essential component of wound healing. The acid isn't only produced within our bodies. It's also been used for decades in various forms. "It was used during World War I to treat wounds in injured soldiers," Dr. Agarwal adds.

What does hypochlorous acid do?

At its core, hypochlorous acid is a powerful antibacterial and anti-inflammatory agent. When applied topically in skincare, it works to disinfect the skin, eliminate harmful bacteria while promoting the healing process making it apt for brides to spritz on mid day.  "It can be helpful as a supportive ingredient for acne. It has antibacterial action, so it can help curb the acne causing bacteria," Dr. Agarwal explains. “It shouldn’t be used as a primary line of care for acne, however it can help in reducing acne causing bacteria since it has antibacterial properties, even reducing future flare ups and helps in faster, natural healing of our skin”, says Dr.Natasha Doshi.

“However, while hypochlorous acid is effective, it isn’t a standalone cure for acne. It can work in combination with other treatments, helping reduce inflammation and preventing future breakouts.”, she adds.

Beyond acne, hypochlorous acid has a range of uses. Its ability to soothe inflamed or irritated skin makes it beneficial for treating eczema, psoriasis, and even sunburn. "It is used in dermatology for eczema, infected wounds, acne, and compromised skin," Dr. Agarwal points out. It reduces redness, calms irritated skin, and even helps to reduce itching, which is key for conditions like eczema where scratching can worsen the problem.

Who can use hypochlorous acid?

One of the standout features of hypochlorous acid is its versatility. It’s suitable for all skin types, including sensitive skin. "Yes, it can be used for all skin types as it is soothing and not harmful," Dr. Agarwal assures. This makes it a great option for people with reactive or sensitive skin conditions.

“It is a product that is safe for sensitive skin too as long as the product doesn’t have any other fragrance or any other irritant. It has fast healing properties and provides an extra boost to your skin barrier. Hence it's great for brides who have sensitive skin or for days when you have outdoor functions under the sun.” adds Dr.Natasha Doshi.

That being said, as with any skincare ingredient, formulation is crucial. "Choose the formulation with care, as it can be drying and irritating if the pH is not appropriate," Dr. Agarwal warns. If the acid isn't properly diluted or stabilised, it can lose its effectiveness or cause irritation.

When and how to use it?

When incorporated into your routine, hypochlorous acid can be a multitasking wonder. Most commonly found in sprays or mists, it can be used throughout the day to refresh and disinfect the skin. "You can start spraying it on your face in the morning after washing your face, then apply the rest of your serums and products a few months before the big day to really see results," says Dr. Agarwal.

She also mentions that it’s especially useful for acne-prone or sun-exposed skin, as its anti-inflammatory properties help soothe and calm. “Since the main purpose is to help reduce the bacterial load on the skin, you can even use it post a workout, on long flights or for brides to be—when you're sweating through your functions. You can also use it on any body parts where there are folds ( elbows, stomach etc ) where you may feel that there is a buildup of bacteria.” says Dr.Natasha.

How do you pick the right Hypochlorous acid?

"There are multiple claims by hypochlorous acid products, but there are no approvals or substantial scientific studies backing these claims," cautions Dr. Agarwal. When shopping for hypochlorous acid products, keep in mind that stability is key. "The formulation of hypochlorous acid is crucial," she adds. “You need to use a trusted product which is diluted to 100 parts per million”, adds Dr.Natasha.

Hypochlorous acid products are generally stable for short-term use, but over time, exposure to light, air, and heat can cause them to oxidise and lose potency. As a result, it's important to choose reputable products and store them properly.
