With a new bottle and pump design, you can now easily dispense the serum without any mess or waste—say goodbye to that annoying spitting pump! Plus, the thicker formula is perfect for targeting those chronically sensitive areas or to use as a spot treatment.


Powered by a concentrated dose of hypochlorous acid, this serum helps deliver softer, clearer, and happier skin. It’s natural, pH balanced (5.5), and formulated especially for facial use (but also safe to use anywhere on your body).


Non-irritating, clinically-tested and dermatologist-approved, this serum comes with three seals of approval, including the National Eczema Association Seal of Acceptance™, National Psoriasis Foundation Seal of Recognition, and the National Rosacea Society Seal of Acceptance.

Ingredients

pH balanced (5.5), alcohol-free, and formulated for facial use, but also safe to use to use anywhere on your skin.

Ingredient List: Ionized Water, Sodium Magnesium, Fluorosilicate, Sodium Chloride, Hypochlorous Acid.


The list of ingredients may change from time to time. Please refer to the product packaging for the most up-to-date information.

How to Use

Use it all over or to target problem areas. Apply two to three pumps on clean, dry skin as part of your AM/PM skincare routine.

Pro Tip: Use SOS Daily Rescue Facial Spray as a toner before SOS Intensive Rescue Serum for a double-hit of hypochlorous acid (your skin loves it!) and the best possible results!

WTF is Hypochlorous Acid?

Like hyaluronic acid + ceramides, ✨hypochlorous acid✨ is made naturally by your skin. It's anti-inflammatory and antibacterial and helps defend your skin from harmful bacteria, reduce redness, and soothe irritation.

F.A.Q.

What is the difference between SOS Serum and SOS Spray?

SOS Serum is a lightweight, water-based treatment serum for chronically sensitive skin (aka acne, rosacea, or eczema) that is more intensive. SOS Spray is a treatment-toner that prevents skin irritation and redness, or just keeps flare-ups at bay.

Is SOS Serum moisturizing?

SOS Serum is designed to soothe, purify, and strengthen the skin barrier. Is it not designed to deliver moisture directly and should be used in conjunction with a moisturizer like SOS Cream.

What skin type is SOS Serum suitable for?

SOS Serum is excellent for skin maintenance in all skin types, but the most visible changes will be seen after consistent use in chronically sensitive/problem skin types. SOS Serum has the National Eczema Association's Seal of Acceptance™ —making it safe for even the most reactive and sensitive skin types.

Can I use SOS Serum with skincare actives like vitamin C?

If you're using an active like vitamin c as part of your skincare routine, we recommend using SOS Serum BEFORE any actives (allowing it to dry down fully first). The hero ingredient in SOS Serum (hypochlorous acid) is super fast acting and once it dries down it won't interact with any of your other skincare products (including actives like vitamin C!

How long do I have to use SOS Serum before I see results?

Real results take time and consistency and not all skin is made the same! Some see results in 3 days, others 3 months, but consistency is key. For best results, use AM/PM in combination with SOS Spray, and SOS Cream + always patch test before adding new skincare products to your routine!

    Cleared my fungal acne! 🙌

    I am obsessed with the new Tower28 SOS Hypochlorous Acid Serum! I’ve been struggling with stubborn fungal acne on and off all summer, and this serum has been the first thing to actually clear it up - and sooo fast! Within one week, my skin looked calmer, smoother, and way less bumpy. In less than a month, the bumps were almost completely gone! Pics taken 3 weeks apart, both with a full face of makeup. The serum absorbs instantly and layers perfectly with everything else in my routine, no pilling or weird texture. The scent is kind of clean, a little like chlorine, but smells similar to the SOS Spray which I’ve used before, so I expected that and honestly don’t mind it. I love the packaging, it is eco-friendly and so easy to close the pump (and comes with a cap!) so excess product doesn’t get wasted and you get your full money’s worth. My skin feels balanced, soothed, and genuinely healthy after using this… it is totally worth it. Highly recommend to sensitive skin girlies and those with fungal acne breakouts!

    Great for redness

    I got the chance to try the SOS Rescue Serum from Tower 28 recently. This is a lightweight serum that contains Hypochlorus Acid so it is very good for acne and clearing bacteria. It helps reduce redness and soothe irritation. I like how it cleared my skin and relieved inflammation. My skin was calm after using this and after continued use, it really cleared up. The pump was easy to use and dispensed the product very easily and nicely. If you have sensitive skin for whatever reason, this will be a good serum to use that will not further irritate you and will actually work to minimize irritation and clear your skin.

    Strong scent but the effects are worth it!

    Although this serum has a strong chlorine like smell, I love the difference it made in my skin. As someone with oily, acne-prone skin, this left my skin feeling calm and reduced my redness. My skin drinks this up and I think all skin types will like this.

    Love the consistency!

    The Tower 28 SOS intensive rescue serum is literally the hypochlorous spray in a serum form which I love especially as a travel essential when I can’t carry the spray. It has a gel like consistency which I love and doesn’t feel tacky. Also sits well with my moisturizer and sunscreen. Definitely helps so much with my redness and soothes and calms my skin whenever it’s inflamed!
