Round Lab Birch Juice Moisturizing Sun Cream SPF50+ PA++++ 자작나무 수분 선크림

⏱ 2 min read
Quick answer: Birch Juice Moisturizing Sun Cream SPF50+ PA++++ is Round Lab's sunscreen, built around Birch Sap and Panthenol (Pro-B5). Dry and normal skin, sensitive skin that tolerates organic filters, and anyone wearing SPF daily through a cold winter when most formulas feel drying.

The sunscreen in Round Lab's birch line: an organic-filter cream with a hydrating, faintly satin finish and panthenol sitting behind the birch sap. It behaves more like a light moisturiser than a sunscreen, which is the point — it targets people whose skin goes tight and flaky under SPF. Scent is minimal and the finish lands closer to natural than dewy, which helps it pass as everyday wear.

What it is built around

🌳 Birch Sap🩹 Panthenol (Pro-B5)

Who it suits

Dry and normal skin, sensitive skin that tolerates organic filters, and anyone wearing SPF daily through a cold winter when most formulas feel drying. It layers under makeup without pilling in most hands. Oily skin will find it too comfortable by afternoon. Deeper skin tones should get no cast from it, but always check in daylight rather than bathroom lighting.

How to use it

Final morning step, two fingers' length for face and neck, applied evenly rather than rubbed in until invisible. Wait a quarter of an hour before going out. If you use it over a rich cream, give the cream time to settle or the two will roll. Reapply outdoors — a stick is easier over makeup.

⚠️ Worth knowing: It is a comfortable daily sunscreen, not a water-resistant one; swimming, heavy sweat and towelling take it off. Sunscreen lines are reformulated more often than people realise, so a tube bought years apart can feel different. And 'moisturising' in a sunscreen name is a texture claim, not licence to skip your actual moisturiser if your skin is dry.
