What can you mix with hypochlorous acid?
- Hypochlorous acid sits happily next to tretinoin.
What it does
Hypochlorous acid is a mild oxidant that white blood cells produce to kill microbes. Stabilised low-concentration solutions are sold as face mists, sprays and gels for acne-prone, irritated or recently treated skin.[1]
Strengths
- A 2025 clinical review describes antimicrobial, anti-inflammatory and healing properties.[1]
- It is used in wound care, atopic and seborrheic dermatitis, acne and after procedures.[1]
- It does not exfoliate, so it is easy to add to most routines.[1]
- Your own white blood cells (neutrophils) make hypochlorous acid as part of the normal immune response to infection.[1]
- Commercial sprays are made by electrolysing salt water and usually sit around 0.01 to 0.02%; the molecule slowly breaks down, so check the expiry date and store the bottle away from heat and sunlight.[1]
Who it suits
Acne-prone or reactive skin, people using strong actives who want a non-irritating step, and skin recovering from procedures when a clinician recommends it.
Who should skip
Expecting it to replace a proven acne treatment. Stop if it stings or causes a rash.
How to start
Mist onto clean skin and let it dry before your next step. It can be used morning and night and between routines, for example after exercise.
Because it is not an exfoliant, it combines comfortably with retinoids, benzoyl peroxide and acids, but let it dry first so it does not dilute them. Keep the bottle closed and away from heat and light; hypochlorous acid breaks down over time, so check the expiry date.
Common questions: Is it the same as bleach? No, skin products use much lower, gentler concentrations.
Does it treat acne? Evidence is limited and mostly from small or clinical studies.
Can I use it on eyelids? Some products are designed for that; check the label.
