Round Lab Birch Juice Moisturizing Sunscreen SPF50+ PA++++ provides broad-spectrum protection against UV radiation, helping prevent sunburn, slow down photoaging, and suppress the formation of pigmentation.
The formula helps prevent dryness and flaking while soothing the skin. It has a soft, creamy texture that spreads easily and leaves no white cast.
The sunscreen contains birch sap (1,425 ppm) sourced from plants grown on Inje Island. This ingredient delivers long-lasting hydration, enriches skin cells with minerals and amino acids, helps prevent dehydration, and slows down age-related changes.
Reliable UV protection is ensured by next-generation, photostable chemical UV filters that do not require reapplication in urban conditions for up to 8 hours:
-
Uvinul A Plus (Diethylamino Hydroxybenzoyl Hexyl Benzoate) — protects against UVA rays.
-
Uvinul T 150 (Ethylhexyl Triazone) — protects against UVB radiation.
-
Tinosorb M (Methylene Bis-Benzotriazolyl Tetramethylbutylphenol) — provides both UVA and UVB protection by absorbing and reflecting UV rays.
-
Iscotrizinol / Uvasorb HEB (Diethylhexyl Butamido Triazone) — a highly photostable, broad-spectrum UV filter that protects against both UVA and UVB rays.
Additional Active Ingredients:
-
Glyceryl Glucoside — a derivative of glycerin and glucose that improves aquaporin function, allowing the skin to better absorb and retain moisture.
-
Vitamin C (Ascorbic Acid) — the most potent, though unstable, form of vitamin C, delivering powerful brightening and anti-aging effects while helping protect against UV-induced oxidative stress.
-
Allantoin — an antioxidant that slows skin aging, reduces sensitivity, and stimulates regeneration.
-
Portulaca Oleracea Extract — supports healing, tightens pores, and helps reduce sebum production.
-
Pine and Chamomile Oils — provide antioxidant and anti-inflammatory benefits, helping soothe irritation and soften the skin.
Suitable for: Normal, combination, and dry skin types.
How to Use: After completing your daytime skincare routine and before applying makeup, apply approximately 1.2 ml of sunscreen to the face and neck 15–20 minutes before sun exposure. When spending time in direct sunlight (e.g., at the beach), reapply every 2 hours
