SOS Rescue Serum

Tower 28 SOS Rescue Serum is the stronger version of the brand's hypochlorous acid treatment — a water-based, liquid-to-gel serum made for skin that is not occasionally irritated but persistently sensitive and inflamed. It is a heavier dose than the SOS spray while staying just as stripped-back: no fragrance, no acids, no actives competing for attention.

What it actually does

• Targets long-running inflammation. Tower 28 designed it specifically for skin that is chronically sensitive or inflamed, rather than for a one-off flare.
• Delivers a concentrated dose of hypochlorous acid. The brand explains that this acid is produced by your own immune system as an early line of defence, fighting the look of redness and acting against unwanted bacteria.
• Soothes and purifies at once. Applied topically, Tower 28 says it cares for stressed skin and leaves it looking clearer, softer and healthier.
• Non-drying by construction. The water and sodium chloride base is isotonic, formulated to mirror the body's own make-up, which is why it carries the active without pulling moisture out.
• pH balanced to 4.5, alcohol-free, made for the face but safe to use anywhere on the body.
• Holds the National Eczema Association Seal of Acceptance™, and the brand describes it as 100 percent natural, derm-tested and clinically proven.
• Gluten-free and cruelty-free.

How to use

1. Two or three pumps, into cupped hands. Press onto clean, dry skin every morning and evening.
2. All over, or only where it hurts. Use it across the whole face, or keep it for the areas that keep flaring.
3. Stack it with the spray if you have both. Tower 28's suggested order is the SOS spray as your toner, then this serum, then your moisturiser — two hits of the same active.
4. Put it before your actives. If you use retinol or vitamin C, apply this first and let it dry down fully before layering them on.

Recycling: the pump is not recyclable — remove it, then take the bottle to a specialist recycler.

Questions

How is this different from the SOS spray?

Strength and format. Both are built on hypochlorous acid, but the serum carries a concentrated dose in a liquid-to-gel texture and is pitched at chronically sensitive, inflamed skin. Tower 28 is clear that despite being more intensive, it is still as gentle as the spray.

Can I use it with retinol or vitamin C?

Yes, and the brand gives the order: apply this first, let it dry down completely, then go in with your active. That sequence means the soothing layer is already in place before the irritating one lands.

Do I need both the spray and the serum?

Not necessarily — but Tower 28 recommends the pair for the strongest result, using the spray as a toner and the serum on top before moisturiser. If you are choosing one, the serum is the more intensive of the two.

Will it dry my skin out?

It is designed not to. The saline base is isotonic, which the brand points out is a non-drying solution mimicking the body's own composition. It is still not a moisturiser, so follow it with one.
