Why we stand behind it
The only hypochlorous acid serum recognized by all three leading U.S. skin health organizations—Eczema, Rosacea, and Psoriasis—it’s powered by a concentrated dose of hypochlorous acid to visibly reduce breakouts, redness + calm irritation. This water-based treatment is pH balanced (4.5), alcohol-free, fragrance-free and safe to use all over the body.
Key ingredients
- Hypochlorous Acid: Naturally produced by the body's immune system, it's anti-inflammatory and antibacterial properties help defend your skin from harmful bacteria, reduce redness, and soothe irritation.
- Water and Sodium Chloride: Act as the optimal delivery solution for hypochlorous acid.

"Okay a little sticky but did feel like it helped soothe my skin"
— RP (4/5)
"The new bottle and pump design is noticeably better and less messy than the original version. However, the reformulated serum seems to be inconsistent because some pumps come out with a gel-like consistency while others are immediately runny."
— Victoria P. (4/5)
"I had dry skin patches around my nose and this cleared it up within a day or two. Light serum, hydrating, no scent and good for sensitive skin."
— Bee (5/5)
"Noticeably calmed irritation, reduced redness, and felt soothing without causing breakouts or dryness"
— Sarah B. (5/5)
"I have really red sensitive skin that flushes easily. I didn’t really notice any change in sensitivity or overall redness"
— Lindsay M. (3/5)
"I’ve been getting periorbital dermatitis (outer corner of my left eye) for the past year, off and on. Haven’t been able to pinpoint yet which product is causing it, so I purchased the SOS serum to soothe it when it happens. It absolutely helps to heal and clear it up quickly, and it helps with the feeling of swelling and itch that occurs with it"
— Amanda (5/5)
"Good for sensitive skin. Just didn’t seem to go the extra mile like other serums I’ve tried."
— Erin P. (4/5)
"I’ve had a patch of eczema on my face for months and decided to give this product a try. Within a week it’s helping my skin stabilize and clear up!"
— Renee V. (5/5)
"I started using the SOS system a couple of weeks ago when my skin had flared up again using something else. My skin was red, angry, cracking and kind of scaly. Already, I have less breakouts and redness, my skin is feeling better, and the scaliness (peeling) is much better. I look forward to seeing what happens as I continue using this. The products I've been using are: the SOS gel cleanser, spray, serum, and moisturizer."
— Abigail C. (5/5)
"Very hydrating"
