See alternativesLow-strength 0.014% spray for sensitive faces
- Key actives: Hypochlorous Acid 0.014%
- Size: 118.3 ml
- Price per ml: $0.13/ml (original $0.16/ml)
The why
A minimalist 0.014% hypochlorous acid spray for post-wash inflammation, itch, and surface-level irritation. It suits reactive, eczema-prone, or rosacea-prone skin, but dry skin may find repeated applications dehydrating and some rosacea users report worsening.
One minus
Can dry already-dry skin
Good forSensitive Skin, Combination Skin, Oily Skin
Both recommended for Eczema.
“I recently started using Briotech spray on my hands and face for my chronic excema and PCOS related acne issues.”

#3
Best for Redness / Irritation
- Size: 298.7 ml
- Price per ml: $0.07/ml (original $0.16/ml)
The why
A plain thermal water spray with nitrogen propellant that people use after cleansing, before moisturizer, or over makeup. It suits reactive, rosacea-prone skin and hard-water sufferers best. Don’t buy it expecting real hydration; some users call it overpriced fancy water.
One minus
Mostly a temporary fix, not a hydrator
Good forSensitive Skin, Dry Skin, Oily Skin
Both recommended for Eczema.
“I use it to rehydrate my skin between the steps of my skincare routine... but it's also soothing for eczema”

- Price per ml: $0.08/ml (original $0.16/ml)
The why
A 0.018% hypochlorous acid mist for post-cleanse use, workouts, and reactive flare days. It suits acne, rosacea, and barrier-stressed skin, though dryness, chlorine odor, and an uneven nozzle make the experience YMMV.
One minus
Can contribute to dryness during reactive flares
