Where Tower 28 wins

Being straight about this matters, because a comparison that finds no merit in the alternative is not a comparison.

• Track record and scale. Tower 28 is largely responsible for hypochlorous acid becoming a mainstream skincare category, and it has a very large user base.
• Rosacea Society Seal of Acceptance. Genuine independent recognition, and meaningful if your primary concern is redness and reactivity rather than breakouts.
• pH 4.5 is well inside the effective band. Hypochlorous acid stays in its active form comfortably at this pH. This is a properly formulated product, not a repackaged sanitiser.
• A refill option exists, which is better on packaging waste than repeat single bottles.
• Wider retail availability through Sephora and other large retailers.

If your goal is calming rosacea-prone skin, Tower 28 is built for that job and is a reasonable choice.

Where SANORA wins

Disclosed concentration

SANORA prints 0.014% (140 ppm) on the label. Tower 28 does not publish a figure. That is not an accusation of weakness, it is an unknown, and concentration is the variable that determines antimicrobial effect. You cannot compare two sprays on strength when only one states its strength. Why concentration matters.

UV-protective glass instead of plastic

Hypochlorous acid degrades on exposure to light and heat, reverting to salt water with no visible change. Recycled plastic is a good environmental choice and a weaker light barrier than opaque glass. In an Australian summer, with the bottle living in a gym bag or a car, that difference compounds and the label stops describing the contents. Why packaging beats ppm.

Dermatologist tested for sensitive skin

Tower 28 holds a rosacea endorsement, which is a real credential for redness. SANORA is dermatologist tested for sensitive skin, which is the relevant test for daily use on skin that is warm, sweaty and often rubbed by a cap or strap.

Published stability figures

Tested potency at six and twelve months. Tower 28 does not publish equivalent figures. For an unstable active this is the most decision-relevant number a brand can give you, and very few do.

Stocked in 100+ Australian gyms, used by 10,000+ Aussie athletes

Distribution where the product is actually used, rather than a beauty aisle. It also means short domestic supply lines: a US product reaching Australia spends weeks in transit and warehousing at uncontrolled temperature, which for this ingredient is not a neutral detail.

Built for the post-workout window

Tower 28 is a redness and sensitivity product that also happens to suit gym use. SANORA is designed around the 30 minutes after training, which drives the bottle size, the packaging and the usage instructions. The window it is built for.

Guarantee

Clearer skin in 30 days or every cent back, refunded on one email.

Which to buy

If your situation is	Choose
Rosacea or persistent facial redness	Tower 28
Breakouts two to four days after training	SANORA
The bottle lives in a gym bag or a hot car	SANORA, for the UV-protective glass
Sensitive skin	SANORA, dermatologist tested for it
You want a stated concentration before buying	SANORA
You are in Australia and want fast domestic dispatch	SANORA
You want the largest possible bottle	Tower 28, for the 4oz and refill

These are different products aimed at different problems. The overlap is the ingredient, not the use case.

Common questions

Is SANORA or Tower 28 better for acne?

For breakouts driven by training and sweat, SANORA is built for that specific window, states its concentration, and ships in UV-protective glass. Tower 28 is formulated primarily for sensitive and redness-prone skin. Both use the same active, but only one publishes how much of it is in the bottle.

What concentration is Tower 28 SOS spray?

Tower 28 does not publish a concentration figure. Its ingredient list is water, sodium chloride and hypochlorous acid, and it is formulated at pH 4.5. For a stated figure you would need to contact the brand.

Is Tower 28 available in Australia?

It is available through various retailers and importers, but it is a US-made product. Since hypochlorous acid degrades with time and heat, transit and warehousing conditions affect how much active remains on arrival.

Does the plastic bottle matter?

For most skincare, no. For hypochlorous acid it does, because light accelerates the breakdown into salt water. Opaque, UV-protective packaging is a functional specification for this ingredient rather than a styling choice, and SANORA is the one using it.

Which is better for sensitive skin?

SANORA is dermatologist tested for sensitive skin. Tower 28 carries a National Rosacea Society Seal of Acceptance, which is specifically about rosacea. Both are fragrance-free and alcohol-free at skin-compatible pH.
