A barrier-focused serum from Korea's number one dermatologist-recommended brand for sensitive skin, the Aestura Atobarrier 365 Hydro CERA-HA Serum combines next-generation hydration technology with clinically proven barrier repair. At its core is Cera-Hyaluronic Acid™ — a patented ingredient exclusive to Aestura that fuses ceramides with hyaluronic acid, delivering moisture that skin appears to retain for longer compared to standard hyaluronic acid alone. Lightweight and fast-absorbing, this serum is suitable for all skin types, including dry, sensitive, and eczema-prone skin.
Key Benefits
- Visibly strengthens the skin barrier — a dual ceramide complex (Ceramide NP and Hydroxypropyl Bispalmitamide MEA) alongside cholesterol and fatty acids replicates the skin's natural lipid structure, helping the barrier appear more resilient and intact
- Deep, lasting hydration — Cera-Hyaluronic Acid™ visibly replenishes moisture-depleted skin, with skin appearing more plump and hydrated with continued use
- Visibly soothes sensitivity — Panthenol and Dipotassium Glycyrrhizate help calm the appearance of irritated, reactive skin
- Skin appears brighter and more even — Niacinamide (Vitamin B3) supports ceramide synthesis and helps skin look more radiant and uniform in tone
- Antioxidant protection — 3-O-Ethyl Ascorbic Acid (a stable Vitamin C derivative) and Tocopherol (Vitamin E) help skin appear protected against environmental stressors
Suitable For
- Dry and dehydrated skin
- Sensitive and reactive skin
- Compromised or weakened skin barrier
- Eczema-prone skin
- All skin types
How to Use
After cleansing, apply 2–3 drops to the face and neck. Gently pat into skin until fully absorbed. Use morning and evening, followed by moisturiser to seal in hydration. For best results, use with the Aestura Atobarrier 365 Cream.
