All about skincare that contains Hypochlorous Acid

Very few people were aware of the mysterious beauty ingredient Hypochlorous Acid (HOCl) until the covid-19 pandemic struck. Previously it was put on the modern beauty market map by brand tower. 28. Owing to its impeccable disinfecting properties, it quickly gained traction and paved its way into the beauty industry as an uber-sensitive skincare component. So, what does this hyped up ingredient have in store for your skin? Let’s find out!

What is Hypochlorous Acid (HCOL)?

If you still haven’t heard of the unicorn of skincare ingredients, it’s time to brush up! Hypochlorous Acid has been around for ages, but because of its powerful disinfecting properties, it came into the limelight only during the coronavirus outbreak. Since it’s a strong antiseptic, naturally, one would assume it wouldn’t be fit for the more sensitive skin types. Well, they would be wrong — the best part about this miracle ingredient is that it is incredibly mild against your skin. You see, our body’s white blood cells produce HOCl naturally and it serves as a viable part of the immune system. Its primary functions are to fight off infections and speed up the body’s wound healing process. So, while most other disinfectants would be potentially dangerous against the skin, HOCl provides you with the best of both worlds!

How it benefits your skin

Hypochlorous Acid exhibits powerful anti-microbial effects, making it very effective against acne and various other skin conditions such as eczema, psoriasis, and rosacea. If you need a wonder ingredient in your skincare products that can take care of acne and clogged pores, HOCl ought to be your go-to!

HOCl works as an anti-inflammatory agent, delivering a soothing sensation to your skin. The compound is widely known for its exceptional wound-healing and damage repair capabilities. If you have sensitive skin and feel iffy about adding a new element to your skincare routine, you’ve got nothing to worry about with HOCl. It’s the ideal non-irritating treatment for any skin type.

What kind of Hypochlorous Acid sprays exist?

HOCl has been incorporated into modern-day skincare in many forms — cleansers, serums, creams, and OTC facial mists. Because topical sprays offer the most convenience in terms of quick, on-the-go use, they are widely preferred. The first spray that put HOCl sprays on the modern beauty map in the skincare world was the Tower 28 SOS Spray. It's probably why we get so many searches for Tower 28 SOS Spray dupe. It is often the case that a cool brand launches and thrusts an ingredient into the spotlight or puts a cool jacket on something that actually was already being used in not so trendy corners of the market to much success.

Four HOCl spray products to add to your skin regimen compared

They essentially have the 3 same ingredients:⁠
- electrolyzed water⁠
- sodium chloride; and⁠
- hypochlorous acid (HOCl), differing slightly on the % of HOCl.⁠
- and Active Skin Repair Spray has "phosphates" as well which the others don't have in their INCIs.⁠

We love when there are many alternative options for a particular subset of the market, in this case, Hypochlorous Acid Sprays. Here are more details of 4 great HOCl skin sprays we identified in our database starting with the trend starter, Tower 28.

Tower 28 SOS Spray
Price: $28 for 120 ml
Tower 28 SOS Spray is an all-natural purifying, repairing, and soothing spray to restore stressed-out skin. Unlike BLDG Active’s HOCl Spray, SOS Spray is more targeted as a skincare product to add to your daily beauty routine. It backs up your skin’s defense system and targets inflammation, reducing redness and irritation. With 0.015% HOCl and isotonic salt (NaCl and electrolyzed water), this spray couples naturally with your body’s HOCl levels.

Briotech Topical Skin Spray
Price: $15.95 240 ml
If you’re looking to get the most bang for your buck, Briotech Topical Skin Spray has the exact same ingredients as Curativa Bay and Tower 28’s HOCl Sprays with 0.014% HOCl. This flagship Briotech product has shown highly beneficial cosmetic results in terms of combating skin conditions like eczema, rosacea, and psoriasis. You can include it in your beauty routine as a gentle exfoliant and anti-wrinkle remedy for your skin. It also works wonders in diminishing the appearance of fine lines and scars.

Active Skin Repair Spray
Price: $24.99 for 88 ml
BLDG Active’s Skin Repair Spray is your go-to natural, non-toxic HOCl solution for everyday skin damage. It’s antibiotic-free, very simple to use, and helps support your body’s natural healing process. What’s more; it’s non-sensitizing so it doesn’t sting when used on wounds and cuts. Its ingredients include sodium chloride (NaCl), sodium hypochlorite (NaOCl) — both of which are known to help cleanse and soothe the skin — phosphates, electrolyzed water and 0.012% of HOCl.

Curativa Bay Advanced HOCl Spray
Price: $21 for 237 ml
Curativa Bay Advanced HOCl Spray is a highly effective product for overall skin health. Its balanced formula makes it an ideal beauty routine companion to combat damaged, acne-prone skin. Not to mention, its facial cleansing and soothing properties are designed to enhance your skin’s appearance. Advanced HOCl Spray contains the same ingredients as the SOS Spray with a 0.02% HOCl concentration.

There you go! This was SKINSKOOL’s comparison of some of the most popular HOCl Sprays on the market. It’s up to you to decide which one speaks to you. All four products have essentially the same ingredients as mentioned above (and as can be seen from the 99%+ Match Scores on our comparison platform if you click through the product names) with one added ingredient in the Active Skin Repair Spray. The variations in cost could be attributed to specific purchase channels, sustainability of packaging, and, in some cases, additional non-profit contributions.
