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!

    Great morning serum

    This is a great lightweight serum that I’ve been using in the mornings for light moisture. It’s similar to the spray which I also use regularly, but in a serum form.

    Perfect serum for my sensitive, eczema-prone skin

    As someone with sensitive and eczema prone skin, I feel like this SOS line has become one of my skins favorite product sets! This serum is a wonderful complement to the other products that I have tried. It has a nice gel, texture and absorbs very quickly into my skin. It doesn’t leave behind a sticky feeling, but instead leaves my skin feeling cared for and soothed. I really like the pump application and how hygienic that is. It’s especially nice that you can lock the pump for storage and travel. Overall, this is something that I like to use whether I’m mid eczema flare up or just trying to avoid one. This is definitely one of those products that I will keep in my arsenal to keep my skin happy.

    SOS Rescue Serum

    Seriously, yes to ANYTHING Tower 28. They don't fail. This serum is lightweight, non-irritating and dries super quickly. I can't say as to how it wears with makeup since I have a six month old I currently feed mommy-milk, and avoid makeup on the daily, but I think based on how well it dries it should do lovely. Great for keeping skin fresh and bacteria-free. This with the SOS spray and the moisturizer, there's your skincare routine and you're good to go! Absolutely love.

    great on eczema skin!

    I use this on my eczema and I have had less flare ups since using it. I love that it's not sticky and quick drying. I don't love the smell, it smells like pool water to me. The pool water scent is a bit too strong for me so I don't like applying it on my face but my eczema is on my leg anyways!

    Love the new addition to the SOS routine

    I love this new addition to the SOS team! I’ve used it for the past two days with my SOS spray. I love that it goes on smooth and doesn’t leave a thick residue behind. So far it’s been leaving my skin nice and refreshed before prepping with some hydration. I will say the scent is a little strong, if you have the SOS spray, it does have that acidic scent if you’re not used to it. But that is the active ingredient - hypocholorus acid. I was a swimmer, so I’m good with the scent - nostalgia. Additionally, like any acid product make sure you’re aware that it can be a bit stingy if you have other products that have acid or retinol. I also LOVE the little cap on top that keeps the product from oozing out if you take her on the go. Overall extremely happy and excited to add it to the rotation in my morning routine. Have loved all my Tower 28 products!
