Active Ingredients (UV Filters):
Avobenzone (Butyl Methoxydibenzoylmethane) 2.7% — UVA protection. Octisalate (Ethylhexyl Salicylate) 4.5% — UVB protection. Homosalate 13.5% — UVB protection. All chemical filters — minimal white cast across all skin tones.

  • Birch Sap (Betula Platyphylla Japonica Juice) — The Moisturizing Base — Round Lab's signature Birch Sap replaces plain water as the hydration base. Naturally rich in minerals, enzymes, proteins, amino acids, and antioxidants. The reason 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 push moisture deeper into skin cells. Reduces skin dehydration even during prolonged outdoor exposure.
  • Niacinamide — Brighten + Barrier — evens skin tone, minimizes pores, and strengthens the barrier alongside the SPF.
  • Mugwort (Artemisia Annua) + Purslane (Portulaca Oleracea) — Calm + Omega-3 — Mugwort calms inflammation and soothes UV-stressed skin. Purslane delivers Omega-3 fatty acids for additional soothing and barrier support.
  • Cauliflower Mushroom (Sparassis Crispa) — Antioxidant Adaptogen — a rare Korean mushroom extract with high beta-glucan content that delivers antioxidant and skin-strengthening benefits.
  • Ascorbic Acid (Vitamin C) + Tocopherol (Vitamin E) — Dual Antioxidant Protection — Vitamin C brightens and adds antioxidant defense. Vitamin E adds fat-soluble antioxidant protection. Both specifically effective against UV-induced free radical damage.
  • Sodium Hyaluronate + Hyaluronic Acid + Allantoin — Hydrate + Soothe — dual HA at two molecular weights plumps and retains moisture. Allantoin calms and soothes.
  • Calcium Aluminum Borosilicate + Polymethylsilsesquioxane + Caprylyl Methicone — Dewy Radiant Finish — Calcium Aluminum Borosilicate gives the subtle radiance. Polymethylsilsesquioxane and Caprylyl Methicone create the silky, dewy, moisturized-skin feel.

Apply liberally and evenly 15 minutes before sun exposure. Reapply at least every 2 hours and after swimming or sweating. Children under 6 months of age: Ask a doctor. Has fragrance. 50ml.
