A moisturizing Korean sunscreen from Round Lab — broad spectrum SPF 45+ protection with zero white cast and a super dewy glow finish. This is the US OTC-registered version, compliant with FDA standards for broad spectrum sun protection. 50ml.

  • Birch Sap (Betula Platyphylla Japonica Juice) — The Moisturizing Base — Round Lab sources birch tree sap rich in natural minerals, enzymes, proteins, amino acids, and antioxidants. It forms a moisture-packed barrier that protects skin from dehydration and replaces plain water as the hydration base — why this sunscreen doubles as a moisturizer for all skin types.
  • Glyceryl Glucoside — Aquaporin Activation — Glyceryl Glucoside is a Nobel Prize-linked molecule that activates aquaporins (the water channels in skin cell membranes), helping moisture flow deeper into skin cells. Reduces the skin's tendency to become dehydrated even under prolonged sun exposure. This is the same active found in the Lagom Aqualicia complex.
  • Niacinamide + Mugwort + Cauliflower Mushroom + Purslane + Vitamin C — Niacinamide brightens hyperpigmentation and supports the barrier. Artemisia Annua (mugwort) is anti-inflammatory. Sparassis Crispa (Cauliflower Mushroom) Extract is an antioxidant adaptogen. Portulaca Oleracea (Purslane) delivers omega-3 fatty acids for soothing. Ascorbic Acid (Vitamin C) adds antioxidant brightening.
  • Chemical SPF — Zero White Cast + Super Dewy Finish — Butyloctyl Salicylate is the primary UV filter — a chemical sunscreen filter that is clear and invisible on all skin tones. No white cast, no graying. Caprylyl Methicone + Polymethylsilsesquioxane create the silky, dewy finish. Calcium Aluminum Borosilicate adds subtle radiance. Reviewers note a super dewy glow that may not suit those who prefer matte.

Apply liberally and evenly 15 minutes before sun exposure. Reapply at least every 2 hours. Fragrance-free. 50ml.
