A nourishing lip balm from Round Lab — built on Inje Birch Sap and a blend of Squalane and five plant oils. The melting balm texture adheres to lip lines on contact, filling in dry cracks and smoothing the lip surface. Long-lasting cushioned finish. Fragrance-free. Vegan. 20g.

• Betula Platyphylla Japonica Juice — Inje Birch Sap — birch sap harvested from Inje, Gangwon Province, one of the cleanest mountain regions in Korea. Rich in amino acids, minerals, and Betulin (a birch-derived compound) that deeply hydrate and condition the lips from within. The same Birch Juice used across the Round Lab Birch Juice skincare line.
• HydroKeep-Barrier™ — Round Lab's Patented Lip Barrier — a proprietary ingredient that forms a protective moisture-locking barrier on the lip surface, shielding against dryness from external factors like wind, cold, and dry air. Keeps the active hydration from the oils and birch juice sealed in rather than evaporating.
• Glyceryl Glucoside — Aquaporin Activation — activates aquaporins, the skin's natural water channels, to deliver moisture deeper into the lip tissue rather than just coating the surface. Works alongside the birch sap for hydration that starts from the inside of the lip, not just the top layer.
• Squalane + 5 Plant Oils — Nourish + Condition — Squalane is lightweight and deeply nourishing without heaviness. Jojoba, Macadamia, Sweet Almond, Argan, and Olive oils provide a full spectrum of fatty acids that condition, soften, and restore the lip barrier with every application.
• Triple HA + Tocopheryl Acetate + Ascorbic Acid — three forms of Hyaluronic Acid (Sodium Hyaluronate, Hydrolyzed HA, Hyaluronic Acid) hydrate at different lip depths. Vitamin E repairs and protects. Ascorbic Acid (Vitamin C) brightens and protects against oxidative stress.

Apply as needed throughout the day. Layer a thicker coat at bedtime for overnight softening and plumping. Fragrance-free. Vegan. 20g.
