Round Lab Birch Juice Moisturizing Serum

The Round Lab Birch Moisturizing Serum is a lightweight, hydrating elixir formulated with 10,000 ppm Betula Platyphylla Japonica (birch) juice, delivering targeted moisture and soothing comfort to all skin types. This refreshing serum features a three-step hydration system: Glyceryl Glucoside opens moisture pathways by promoting aquaporin production, birch sap enhances moisture retention, and multiple forms of Hyaluronic Acid (including hydrolyzed and sodium hyaluronate) lock in hydration and plump the skin, reducing the appearance of fine lines.

Enriched with 17 amino acids, minerals, antioxidants, and vitamins, the birch sap purifies, calms inflammation, and helps brighten and clarify skin. Additional botanicals like Eclipta Prostrata leaf extract and beta-glucan contribute antioxidant and soothing properties. The serum’s airy, non-greasy, watery texture absorbs rapidly, leaving a silky dewy finish suitable even for sensitive or combination skin.

To use, apply a moderate amount after toner and gently pat in for full absorption. Users on iHerb rave that it’s “gentle, good for sensitive skin, truly moisturizing,” with a light, non‑sticky feel that leaves skin calm and refreshed.
