ROUND LAB - Birch Juice Moisturizing Drop Serum 50ml

ROUND LAB Birch Juice Moisturizing Drop Serum is a deeply hydrating formula designed to strengthen and care for dry, compromised skin barriers. It combines the Hydro-Keep Barrier system, nano hyaluronic acid broken down into particles smaller than pores, and Nano-Din PDRN to replenish moisture deep within the skin. Inje birch sap, rich in amino acids and minerals, adds a refreshing hydration boost, while glyceryl glucoside from the resurrection plant supports the skin’s moisture pathways for lasting hydration and a firmer, more resilient feel.

Key Benefits

• Deep hydration: nano hyaluronic acid reaches below the surface.
• Barrier care: Hydro-Keep Barrier for dry, compromised skin.
• PDRN support: for resilient, healthy-looking skin.
• Lightweight drops: layers easily under cream and SPF.

How to Use

After toner, apply 2–3 drops to the face and press in gently. Follow with a Birch Juice cream to lock in moisture. Use morning and night.
