ROUND LAB Birch Juice Intensive Moisturizing Lip Balm relieves dryness, softens the lips, and helps smooth the appearance of fine dry lines. Birch sap from the Inje region, combined with glyceryl glucoside, supports the skin’s natural moisture balance, while Hydrokeep-Barrier™ technology helps reduce moisture loss. Squalane and five plant oils—olive, sweet almond, jojoba, macadamia, and argan oil—nourish the lips, while a hyaluronic acid complex helps bind moisture, leaving the lips soft, smooth, and fuller-looking. The melting texture leaves a comfortable protective layer on the lips, is fragrance-free, and is suitable for all skin types, including sensitive lips.
