ROUND LAB Birch Juice Moisturizing Lip Balm has a melting, slightly sticky balm texture that settles gently into lip lines and leaves a smooth shine. Inje birch sap, rich in amino acids and minerals, keeps lips moist all day, while glyceryl glucoside helps open the skin’s moisture pathways (aquaporins) for longer-lasting hydration. A blend of olive, sweet almond, argan, jojoba and macadamia oils keeps lips soft and smooth.

Key Benefits

  • All-day moisture: birch sap and glyceryl glucoside for lasting hydration.
  • Smooth, glossy finish: melts into lip lines for a soft shine.
  • Five nourishing oils: protect lips stressed by weather and dryness.
  • Tested: skin irritation test and German derma test completed.

How to Use

Apply to lips as often as needed throughout the day. Use a thicker layer before bed as an overnight lip treatment, or under lipstick to prep dry lips.
