Developed by AESTURA — Korea's number one dermatologist-recommended skincare brand — the Atobarrier365 Hydro Cera-HA Ampoule is a concentrated hydration treatment designed to deeply replenish moisture and reinforce the skin's natural barrier in a single step.

At the heart of the formula is the brand's Cera-HA Complex: a proprietary pairing of bio-mimetic ceramide (Hydroxypropyl Bispalmitamide MEA) and Sodium Hyaluronate that delivers intense, lasting hydration while rebuilding the skin's protective lipid barrier. This is supported by a Triple Lipid Complex — Ceramide NP, Cholesterol, and Sphingolipids — that closely mimics the natural lamellar structure of healthy skin, helping to restore what environmental stress, cleansing, and dehydration break down over time.

Additional actives include Niacinamide for barrier-boosting and tone-refining benefits, a stable 3-O-Ethyl Ascorbic Acid (Vitamin C derivative) for antioxidant protection and glow, Dipotassium Glycyrrhizate for anti-inflammatory soothing, and Adenosine for elasticity support. Panthenol and Betaine provide further humectant hydration, while Biosaccharide Gum-1 helps lock moisture to the skin's surface.

The lightweight, gel-like texture absorbs quickly and cleanly — no heaviness, no stickiness. Clinically tested on sensitive skin over 4 weeks with confirmed safety. Free from fragrances, harsh alcohols, parabens, and silicones.

Formulated specifically for dry, dehydrated, and sensitive skin — including skin that is barrier-compromised, eczema-prone, or reactive to conventional actives. Particularly beneficial for:

4-week extremely sensitive skin safety tested. Free from fragrances, essential oils, harsh alcohols, parabens, and silicones. Does not contain animal-derived ingredients.
