What it is & why it works  

What it is: A dermatologist-tested hydrating ampoule from AESTURA, Korea's No.1 derm-recommended brand for sensitive skin, built on patented Cera-HA™, a hyaluronic acid-ceramide blend that holds twice the moisture of hyaluronic acid alone.
Why it works: Hyaluronic acid draws water into the skin, but on a weakened barrier that water escapes just as fast. Cera-HA™ bonds hyaluronic acid to ceramide, the lipid that holds the barrier together, so moisture is both delivered and kept. A triple lipid complex of cholesterol, sphingolipids and fatty acids mirrors the skin's own barrier structure, while niacinamide and panthenol calm and strengthen. In clinical testing, inner hydration rose 281% within 5 minutes, moisture was retained for up to 72 hours, and the skin glow index improved by 111%; used with Atobarrier 365 Cream, hydration rose a further 124%. Hypoallergenic, non-comedogenic and suitable for eczema-prone skin.

How do I use & layer this?  

AM: Cleanse (gentle wake-up wash) → Tone/Mist (quick hydrating sip) → Treat (essence/serum/ampoule) → Eye cream (tap gently around the eye area) → Moisturize (seal in hydration) → SPF (don’t skip!).
PM: Double cleanse (oil/balm to remove makeup & SPF → water-based cleanser) → Tone/Mist → Masks or Devices (optional; 2–3 times a week) → Treat (essence/serum/ampoule) → Eye cream → Moisturize.

New to K-Beauty? Follow the “thin → thick” rule: start with watery (toner/essence) → then lighter serums → then cream → finish with sunscreen in the morning.
Caution: Avoid layering strong acids (AHA/BHA/PHA/peeling solutions) with retinoids on the same night, and introduce actives slowly if you have sensitive skin.
