Aestura Atobarrier365 Hydro Cera-Ha Ampoule

Aestura Atobarrier365 Hydro Cera-HA Serum is a 30ml serum-ampoule developed by the AMOREPACIFIC brand, recommended by dermatologists as #1 in Korea. Its foundation is the proprietary Cera-Hyaluronic Acid™ (Cera-HA™) technology - a patented new generation Hyaluronic Acid molecule, combined with Ceramides, which allows for twice as long moisture retention in the skin compared to traditional Hyaluronic Acid.

Key technology: Cera-HA™

• Cera-Hyaluronic Acid™ contains 1001 ppm Hyaluronic Acid combined with two types of ceramides: 210 ppm Hydroxypropyl Bispalmitamide MEA and 0.75 ppm Ceramide NP. • AMOREPACIFIC's proprietary technology stabilizes water-insoluble ceramides in a water-based formula. • Ceramides support the reconstruction of the lamellar structure of the skin's lipid barrier (ceramides + cholesterol + fatty acids), while Hyaluronic Acid seals moisture from within.

Key ingredients

• Cera-HA™ (Hydroxypropyl Bispalmitamide MEA + Ceramide NP + Sodium Hyaluronate) — deep hydration and skin barrier regeneration. • Niacinamide (Vitamin B3) — strengthens skin barrier function and supports a radiant complexion. • 3-O-Ethyl Ascorbic Acid — stable Vitamin C derivative with brightening action. • Adenosine — anti-aging, smoothing effect. • Panthenol — soothes and conditions the skin. • Dipotassium Glycyrrhizate — has a soothing and anti-inflammatory effect.
