Birch Juice Moisturizing Ampoule

For deep-level skin quenching

The Deep-Level "Quencher"

A concentrated surge of hydration that targets "inner dryness." Formulated with high-density Birch Sap and Glyceryl Glucoside, it "opens" the skin's moisture pathways to ensure hydration reaches the deeper layers of the dermis.

Why it’s a Real Gem: For its weightless yet powerful performance. It plumps fine lines and restores vitality to tired complexions without any sticky residue.

Best For: Deleting that "inner dryness" and tight-skin feeling. Perfect for anyone wanting to re-plump their complexion and get back to a juicy, bouncy glow—even when the air around you is bone-dry.

Key Ingredients
Inje Birch Sap Harvested from birch trees grown in the cool climate of Inje, rich in amino acids and minerals to help moisturize dry skin. 10 Types of Hyaluronic Acid A blend of high-, medium-, and low-molecular hyaluronic acids that delivers deep hydration to both the skin surface and inner moisture layers. Glyceryl Glucoside A key component derived from the Resurrection Plant (Jericho rose) that helps activate aquaporins (skin water channels) to support efficient moisturization. Aquaxyl® (Patented Moisturizing Complex) A combination of birch- and beech-derived xylitol with glucose that helps prevent moisture loss and maintain long-lasting hydration.
How to Use
After toner, apply 1–2 pumps and gently spread over the face. Pat until fully absorbed, then follow with moisturizer. When: AM & PM. Actives tip: Pair with barrier creams when using actives.
