ROUND LAB - Birch Juice Moisturizing Lip Balm 20g

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.
