Round Lab Birch Juice Moisturizing Serum 50ml

Round Lab Birch Juice Moisturizing Serum is a K-beauty hydrating serum built around a patented 3-Step Moisture Care system — designed to open, replenish, and lock in skin hydration at every layer. Sourced from the pristine Inje region of the Taebaek Mountains in South Korea, the Birch Sap (Betula Platyphylla Japonica Juice) is harvested in spring from Silver Birch trees before their leaves emerge — capturing the tree’s most concentrated flow of natural moisturizing factors including 17 amino acids, minerals, enzymes, proteins, antioxidants, and vitamins. At 10,000ppm, this iconic ingredient reduces inflammation, purifies pores, boosts moisture retention, and delivers a unique softness and clarity to the skin.

The 3-Step Moisture Care system works as follows: Glyceryl Glucoside stimulates the production of Aquaporins — the skin’s natural water channel proteins — effectively opening moisture pathways and enhancing absorption of all hydrating ingredients that follow. Birch Sap then floods the skin with its rich Natural Moisturizing Factor (NMF) complex to supercharge moisture retention. Finally, a 3-type Hyaluronic Acid complex — Sodium Hyaluronate (surface hydration), Hydrolyzed Hyaluronic Acid (deeper penetration via smaller molecules), and Hyaluronic Acid (barrier sealing) — forms a multi-depth moisture defense barrier that locks in hydration, plumps fine lines, and maintains a dewy, healthy complexion throughout the day.

Beta-Glucan delivers additional long-lasting hydration and barrier support. Ascorbic Acid (Vitamin C) brightens and evens skin tone while providing antioxidant protection. Eclipta Prostrata Leaf Extract calms irritation and strengthens the skin. Laminaria Japonica (Kelp) Extract and Oat Kernel Extract soothe and nourish sensitive skin. Dipotassium Glycyrrhizate reduces redness and inflammation. The lightweight watery-silky texture absorbs instantly without residue, stickiness, or heaviness. EWG green certified — fragrance-free, vegan, cruelty-free.
