A moisturizing Korean sunscreen from Round Lab — broad spectrum SPF 45+ with minimal white cast and a super dewy finish. The US OTC-registered version, compliant with FDA standards for broad spectrum sun protection. Chemical formula — clear on all skin tones. Note: reviewers mention a super dewy glow finish that may not suit those who prefer matte. Fragrance-free. 50ml.

  • Birch Sap (Betula Platyphylla Japonica Juice) — The Moisturizing Base — Round Lab birch tree sap is rich in natural minerals, enzymes, proteins, amino acids, and antioxidants. It replaces plain water as the hydration base — why this sunscreen doubles as a moisturizer. Skin stays hydrated throughout the day, even under sun exposure.
  • Glyceryl Glucoside — Aquaporin Activation — activates aquaporins (water channels in skin cell membranes) to help moisture flow deeper into skin cells. The Nobel Prize-linked molecule that reduces skin dehydration even during prolonged outdoor exposure.
  • Niacinamide + Mugwort + Cauliflower Mushroom + Purslane + Vitamin C — Niacinamide brightens and supports the barrier. Artemisia Annua (mugwort) calms inflammation. Sparassis Crispa (cauliflower mushroom) is an antioxidant adaptogen. Portulaca Oleracea (purslane) delivers Omega-3 for soothing. Ascorbic Acid adds brightening antioxidant protection.
  • Chemical SPF — Minimal White Cast + Super Dewy Finish — Homosalate 13.5%, Octisalate 4.5%, and Avobenzone 2.7% form the broad spectrum chemical filter system. Chemical sunscreen filters are clear and invisible — minimal white cast on all skin tones. Caprylyl Methicone and Polymethylsilsesquioxane create the silky dewy finish. Calcium Aluminum Borosilicate adds subtle radiance.

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