SOS Daily Rescue Facial Spray
A clinically proven, dermatologist-approved hypochlorous acid facial spray that calms redness, fights breakout-causing bacteria, and soothes stressed, angry skin. With only 3 ultra-clean ingredients and a pH of 4.5, this toner treatment is recognized by the National Eczema Association, National Rosacea Society, and National Psoriasis Foundation.
β¨ Texture & Feel
Antibacterial Defense
Hypochlorous acid kills acne-causing bacteria on contact while being gentle enough for eczema-prone skin.
Anti-Inflammatory Action
Clinically shown to reduce visible redness in just 60 minutes. Calms irritation, flare-ups, and post-workout skin stress.
Barrier Support
Strengthens and supports the skin barrier without stripping moisture. Works with your body's natural immune system.
Post-Workout Essential
Purifies skin after sweating to prevent breakouts. Spray anytime, anywhere β over makeup, post-gym, or post-procedure.
π‘οΈ Safety & Compatibility
Contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. Hypochlorous acid has zero systemic absorption and is naturally produced by the body. Safe for all trimesters.
Contains no ferments, fatty acids, esters, polysorbates, or oils that feed Malassezia yeast. The 3-ingredient formula is one of the safest options for fungal acne sufferers.
Holds the National Eczema Association Seal of Acceptance. Also recognized by the National Rosacea Society and National Psoriasis Foundation β the only HOCl spray with all three endorsements.
Zero comedogenic ingredients. Contains only water, sodium chloride, and hypochlorous acid β no oils, waxes, or pore-clogging compounds.
Apply before retinol, AHA, BHA, or vitamin C and let it dry fully first. HOCl is fast-acting and won't interact with subsequent products once absorbed.
HOCl is an oxidizer and may neutralize strong antioxidants like vitamin C if applied simultaneously. Allow the spray to dry completely (30β60 seconds) before applying vitamin C serum.
π¬ Ingredient Breakdown
β‘ Hypochlorous Acid (HOCl) 0.015% Proven
The hero ingredient β a molecule naturally produced by your white blood cells as a first line of immune defense. Tower 28's chemists spent 8 years stabilizing this notoriously fickle compound for optimized facial use at pH 4.5.
- Mechanism: Destroys bacterial cell walls through oxidative action while leaving healthy skin cells unharmed.
- Clinical: 100% of participants saw reduced redness after 1 hour; 100% saw decreased blemishes after 4 weeks (third-party study, 30 participants).
- Research: Widely used in wound care and dermatology. FDA-cleared for medical use. Effective against bacteria, viruses, and fungi without contributing to antibiotic resistance.
π§ Electrolyzed Water ~99% Proven
Purified, deionized water that serves as the base and optimal delivery vehicle for hypochlorous acid. The electrolysis process is what generates HOCl from the water and salt solution.
- Function: Acts as a solvent and carrier, ensuring even distribution of HOCl across the skin surface.
- Purity: Pharmaceutical-grade water ensures no contaminants interfere with HOCl stability or skin compatibility.
π§ Sodium Chloride (NaCl) Trace Proven
Medical-grade salt that creates the isotonic saline environment needed to keep hypochlorous acid stable and effective. Mimics the body's natural salt balance.
- Function: Stabilizes the HOCl molecule and creates a pH-balanced solution compatible with skin's natural chemistry.
- Safety: Isotonic salt solutions are used universally in wound irrigation and nasal sprays β extremely well-tolerated.
3 ingredients
Water/Aqua/Eau, Sodium Chloride, Hypochlorous Acid.
π Where It Fits in Your Routine
Use AM + PM after cleansing. Can also be sprayed over makeup throughout the day or post-workout. Let dry fully before applying next products.
π How to Use
Cleanse Your Face
Start with clean, dry skin. Use a gentle cleanser and pat dry. SOS Spray works best on a freshly cleansed surface.
Mist Generously
Hold the bottle 8β10 inches from your face and spray 3β5 pumps evenly across your skin. Focus on problem areas like redness, blemishes, or irritation.
Let It Dry Down
Allow 30β60 seconds for the spray to fully absorb and dry. This ensures the HOCl has time to work its antibacterial and anti-inflammatory action.
Continue Your Routine
Follow with your serum, moisturizer, and sunscreen. The spray won't interfere with subsequent products once it has dried down completely.
π€ Who Is It For?
β Perfect for you if:
- You have sensitive, reactive, or easily irritated skin
- You deal with redness, rosacea, or eczema flare-ups
- You break out after workouts, wearing masks, or sweating
- You want a minimalist, ultra-clean ingredient list
- You need something pregnancy and breastfeeding safe
- You want a calming toner that won't disrupt your barrier
β Consider alternatives if:

- You prefer exfoliating toners with AHA/BHA actives
- You want anti-aging benefits like retinol or peptides
- You find the price-per-ounce too high for a simple formula
π― Skin Type Compatibility
Weightless watery formula adds zero oil or shine. Antibacterial action helps manage excess sebum-related breakouts.
Calms irritation well but provides no hydration. Must be paired with a rich moisturizer β not a standalone solution for dry skin.
Works beautifully across different face zones. Purifies oily T-zone while calming drier, more sensitive areas without over-drying.
Specifically formulated for sensitive skin. NEA Seal of Acceptance certified. No fragrance, alcohol, or known irritants in the formula.
Non-comedogenic (0/5), fungal acne safe, and antibacterial. Targets acne-causing bacteria without the dryness of benzoyl peroxide.

β Frequently Asked Questions
Yes. The SOS Spray contains only water, sodium chloride, and hypochlorous acid β none of which are on the restricted list for pregnancy or breastfeeding. HOCl is naturally produced by your immune system and has zero systemic absorption, meaning it does not enter the bloodstream. There are no retinoids, salicylic acid, hydroquinone, or chemical sunscreens in this product. It is considered safe for all trimesters and while nursing. Always consult your healthcare provider if you have specific concerns.
Yes. With only 3 ingredients β water, sodium chloride, and hypochlorous acid β this formula contains absolutely no ferments, fatty acids, esters, polysorbates, or oils that feed the Malassezia yeast responsible for fungal acne. It is one of the safest products available for fungal acne sufferers. The antibacterial properties of HOCl can also help manage bacteria that contribute to breakouts alongside fungal concerns.
Yes, but with one important note: apply SOS Spray first and let it dry completely (30β60 seconds) before applying actives. HOCl is an oxidizing agent, so applying it simultaneously with strong antioxidants like vitamin C may reduce the efficacy of the vitamin C. Once dried, HOCl will not interact with retinol, AHA, BHA, or other actives. Tower 28 recommends using SOS Spray before any actives in your routine.
SOS Spray is excellent for sensitive, acne-prone, oily, and combination skin types. It was specifically designed for reactive skin and holds the National Eczema Association Seal of Acceptance. Those with rosacea, eczema, psoriasis, and acne report the most dramatic results. Dry skin types can benefit from its calming properties but will need to pair it with a hydrating moisturizer, as it does not provide moisture on its own.
Results vary by individual: clinical studies show 100% of participants saw redness improvement within 1 hour and blemish reduction within 4 weeks. Many users report visible changes in 3β7 days with consistent AM/PM use. Tower 28 notes that some see results in 3 days while others need up to 3 months. Consistency is key β for best results, use twice daily along with SOS Serum and SOS Cream.
Use SOS Spray as step 2 in your routine, immediately after cleansing and before any serums or treatments. It functions as a toner/treatment spray. Spray onto clean, dry skin, let it dry down fully, then continue with your serum, moisturizer, and sunscreen. You can also use it throughout the day over makeup, post-workout, or whenever your skin needs a calming reset.
No. Tower 28 SOS Spray has a comedogenic rating of 0 out of 5. The formula contains only water, salt, and hypochlorous acid β there are no oils, waxes, silicones, fatty acids, or any other ingredients known to clog pores. It is fully non-comedogenic and safe for acne-prone skin. In fact, its antibacterial action actively helps keep pores clear.
The recommended period after opening (PAO) is 6 months. Hypochlorous acid is inherently unstable and will lose potency over time, particularly when exposed to air, light, and heat. Store your bottle in a cool, dry place away from direct sunlight. Do not transfer the product to a different container, as air exposure during decanting accelerates degradation. Check the expiration date printed on the bottle for the unopened shelf life.
Verdict: Tower 28 SOS Daily Rescue Facial Spray is a standout product for anyone struggling with redness, sensitivity, breakouts, or reactive skin. Its ultra-minimal 3-ingredient formula β backed by clinical data and triple endorsement from major U.S. skin health organizations β makes it one of the safest, most trustworthy facial sprays on the market. It excels at what it does: calming inflammation, fighting bacteria, and supporting skin barrier health. The main caveat is value β at $7 per ounce, you're paying a significant premium for a formula that cheaper HOCl sprays closely replicate. If you prioritize the refined sprayer, the stabilization R&D, and the brand's clean beauty certifications, it is well worth the investment. For budget-conscious buyers, BRIOTECH offers an excellent near-identical alternative at a fraction of the cost.
