MEDICUBE Hypochlorous Acid Power Soothing Spray

MEDICUBE Hypochlorous Acid Power Soothing Spray

Calm, refresh, and purify stressed-looking skin with the MEDICUBE Hypochlorous Acid Power Soothing Spray, a pH-balanced facial toner mist designed to soothe irritation, reduce the look of redness, and support clearer-looking skin with a fresh, weightless finish. Formulated with 150ppm Hypochlorous Acid (HOCl), 2% Niacinamide, Panthenol, Allantoin, Eucalyptus Globulus Leaf Oil, Rosmarinus Officinalis (Rosemary) Leaf Oil, Melaleuca Alternifolia (Tea Tree) Leaf Oil, Sodium Citrate, and Citric Acid, this ultra-fine mist delivers clinically validated antibacterial, barrier-supporting, and soothing care in seconds — with no rinsing, no patting, and no sticky finish.

Hypochlorous Acid (HOCl) is a substance naturally produced by the body's own immune system to fight bacteria and reduce inflammation — the same molecule your white blood cells produce to neutralize harmful pathogens. At 150ppm in a stabilized, pH-balanced mist formula, it targets C. acnes bacteria directly while calming the inflammation and redness that breakout-prone and sensitive skin experience. 2% Niacinamide refines texture and brightens. Panthenol and Allantoin deliver lightweight barrier-supporting hydration. A trio of botanical oils — Eucalyptus, Rosemary, and Tea Tree — adds purifying, freshness, and soothing properties.

The MEDICUBE Hypochlorous Acid Power Soothing Spray is a great option for anyone looking for a K-beauty soothing spray, hypochlorous acid facial spray, or refreshing toner mist for acne-prone and sensitive skin. Fragrance-free, alcohol-free, paraben-free, sulfate-free, non-comedogenic, vegan, and cruelty-free.

Size: 125ml

Why we love it

Facial mists occupy a space in skincare where format and feel often matter more than actual efficacy — but the MEDICUBE Hypochlorous Acid Power Soothing Spray is built differently. Hypochlorous Acid (HOCl) is not a trendy botanical extract — it's an endogenous molecule that the human immune system produces naturally to eliminate pathogens and reduce inflammation. Your white blood cells make it. At 150ppm in a stabilized, pH-balanced formula, it delivers the same antibacterial and anti-inflammatory action topically: the 96.330% C. acnes inhibition rate from CUTIS BIOMEDICAL RESEARCH CENTER testing is not a marketing claim but a measure of genuine antibacterial efficacy at a real concentration. The 13.2% skin barrier improvement from a single use reflects HOCl's anti-inflammatory action on the compromised barrier that sensitive and acne-prone skin typically has — reducing the inflammatory signaling that degrades barrier function, rather than just adding a moisture layer on top of it. The 2% Niacinamide adds brightening and texture refinement to a mist that most competitors position solely as a soothing product. The three-oil complex of Eucalyptus, Rosemary, and Tea Tree provides purifying, freshness-enhancing, and soothing properties in the airborne fine mist without the irritation risk of alcohol or fragrance compounds — and the formula is pH-balanced specifically so the HOCl remains active and stable. At BestSkincareUSA.com, it's the leave-on soothing mist we recommend most from MEDICUBE for reactive, acne-prone, and sensitive skin in any Korean skincare routine.

Key ingredients deeper dive

• Hypochlorous Acid (HOCl) 150ppm — the immune system's own antimicrobial and anti-inflammatory molecule, now in a stabilized mist — Hypochlorous Acid is produced naturally by neutrophils (white blood cells) as part of the human immune response to eliminate bacteria, fungi, and viruses while reducing inflammation. In skincare, stabilizing HOCl at the correct pH and concentration is the formulation challenge — it is unstable and degrades rapidly without precise pH-balancing. The MEDICUBE Hypochlorous Acid Power Soothing Spray's pH-balanced formula maintains the HOCl at 150ppm in its active form — delivering 96.330% C. acnes inhibition rate in CUTIS BIOMEDICAL RESEARCH CENTER testing while remaining gentle enough for daily use on sensitive skin across all Korean skincare skin types.
• 2% Niacinamide — brightening, texture refinement, and barrier support in a mist format — Most facial mists contain little more than water and glycerin. The inclusion of 2% Niacinamide in the MEDICUBE Hypochlorous Acid Power Soothing Spray elevates it to an active treatment mist: Niacinamide inhibits melanosome transfer for brightening, refines the appearance of pores and texture, and further strengthens the skin barrier alongside the HOCl's anti-inflammatory barrier support. Together with HOCl, the Niacinamide and barrier-improvement results compound — the 13.2% single-use barrier improvement reflects the HOCl's inflammation reduction alongside Niacinamide's barrier-supporting action.
• Panthenol and Allantoin — lightweight hydration and barrier comfort without heaviness — Panthenol (Provitamin B5) penetrates the skin to provide deep humectant moisture and barrier-strengthening support — the same active used at 5% as a primary ingredient in the MEDICUBE Zero Pore One-day Cream, here in a mist format delivering quick barrier comfort with every spray. Allantoin soothes post-inflammatory skin and supports healthy cell turnover — making the combination particularly effective for calming the active irritation that sensitive and acne-prone skin experiences throughout the day.
• Eucalyptus Globulus, Rosmarinus Officinalis (Rosemary), and Melaleuca Alternifolia (Tea Tree) Leaf Oils — a purifying botanical oil trio for freshness and skin balance — Three botanical oils provide a purifying and freshness-enhancing complex that complements the HOCl's antibacterial action: Eucalyptus Globulus Leaf Oil delivers cooling, purifying, and antimicrobial properties; Rosemary Leaf Oil provides antioxidant protection and skin-balancing benefits; Tea Tree Leaf Oil — the same Melaleuca Alternifolia used in the MEDICUBE Red Serum Plus — provides additional antibacterial and anti-inflammatory action. All three are included at concentrations calibrated for the fine mist delivery format — effective without irritation risk.
• Sodium Citrate, Citric Acid, and Sodium Gluconate — pH-balancing and formula stability for active HOCl delivery — These three compounds work together to maintain the precise pH range in which Hypochlorous Acid remains stable and active. Sodium Citrate and Citric Acid form a citrate buffer system that holds the formula at the optimal pH for HOCl effectiveness; Sodium Gluconate chelates metal ions that would otherwise degrade the HOCl. The pH-balancing system is what makes the MEDICUBE Hypochlorous Acid Power Soothing Spray clinically effective rather than simply containing HOCl in name — without it, the HOCl would degrade before reaching the skin.

Who it's for

The MEDICUBE Hypochlorous Acid Power Soothing Spray is designed for all skin types — particularly sensitive, acne-prone, combination, and easily irritated skin dealing with redness, breakouts, inflammation, and daily environmental stress. It's especially effective for those who want a clinically validated leave-on antibacterial mist that can be used multiple times daily without irritation, for those building a complete MEDICUBE acne-prone skin routine alongside the MEDICUBE Red Foam Cleanser and MEDICUBE Red Serum Plus, and for anyone who wants a truly portable, on-the-go skin reset that actually works. Fragrance-free, alcohol-free, non-comedogenic, vegan, and cruelty-free.

Pro tips and pairings

Hold the MEDICUBE Hypochlorous Acid Power Soothing Spray at 10–20cm from the face and close your eyes before misting — this distance produces the most even, ultra-fine coverage. Let the mist absorb completely before applying serums or moisturizer after cleansing — the HOCl needs brief contact time on the skin surface to complete its antibacterial action. When using mid-day over makeup, hold slightly further at 20cm for a finer, less disruptive mist. For a complete MEDICUBE Red Line routine for acne-prone skin: cleanse with the MEDICUBE Red Foam Cleanser, mist with this spray as the toner step, and follow with the MEDICUBE Red Serum Plus for a layered antibacterial, soothing, and pore-care routine morning and evening. Keep a bottle in your gym bag, at your desk, and in your travel kit — the 125ml size makes it ideal for home use, and the lightweight formula stays fresh under daily misting.
