You can totally use Tower 28 SOS spray in the morning — but only if you’re fine with your $45 SPF doing absolutely nothing. Hypochlorous acid + chemical sunscreen = a chemical reaction that nukes your UV filters in under 30 minutes.
Here’s the thing dermatologists don’t say on Instagram: that same bacteria-killing magic that clears your acne at night literally oxidizes your sunscreen actives in broad daylight. I learned this the hard way after a sunburn through SPF 50. Cute.
It’s $28 for 4 oz of hypochlorous acid — basically your body’s own immune response in a bottle. I bought it because TikTok wouldn’t shut up about “acne spray” and I was desperate.
Hypochlorous Acid 0.01%
Kills acne bacteria on contact without nuking your moisture barrier
Salt + Electrolytes
Balances the formula so it doesn’t sting like straight bleach water
No Preservatives Needed
The molecule self-neutralizes after 60 seconds — weirdly cool
Your white blood cells literally produce hypochlorous acid to fight infection. This bottle is just stabilized versions of that. The hero: hypochlorous acid (HOCl) — it shreds bacterial cell walls on contact, then turns into saline water.
- Hypochlorous Acid: Oxidizes acne bacteria in 60 seconds
- Sodium Chloride: Keeps pH skin-neutral so it doesn’t burn
- Electrolyte Blend: Prevents that weird tight feeling after spraying
- Water: The carrier that evaporates in 10 seconds
Straight water. No scent. No residue. Dries in 10 seconds flat — I timed it. First spray felt like nothing, which freaked me out because I wanted drama. The real shock: it doesn’t sting broken skin. At all.
By week two, my chin cysts were smaller but not gone. What surprised me? It actually calmed my rosacea redness better than my prescription cream. No joke — the anti-inflammatory effect hits in 20 minutes.
Active acne reduced by maybe 40% in three weeks. My redness? Down 70%. The weird part — my oil production actually balanced out around week three. Not dry, not greasy. Just… normal.
Keep it for nighttime only unless you’re using mineral SPF. It’s a solid staple — not magic, but better than most hype. My skin is less angry, which is all I wanted.
