SPF50+ PA++++Reef-SafeNo White Cast

Round Lab Birch Juice Moisturizing Sun Cream

Korea's bestselling SPF — maximum UV protection with the hydration of a daily moisturizer. No white cast, no grease, no pilling.

✦ SPF50+ PA++++ — the highest UV protection rating available, with next-gen photostable filters that stay effective all day, even in sunlight. Plus 1,425ppm of pure birch sap for real skincare benefits.

What it does

Maximum broad-spectrum UV protection
Four next-generation chemical UV filters (including Tinosorb M) cover the full UVA + UVB spectrum. Highly photostable — maintains SPF protection throughout the day without degrading in sunlight.
Moisturizes as it protects
1,425ppm birch sap from Inje's forests delivers 17 amino acids, minerals, and antioxidants — hydrating skin from within while dual hyaluronic acid locks moisture in all day.
Brightens & evens tone
Niacinamide helps reduce hyperpigmentation and redness from UV exposure, while adenosine supports collagen production for firmer, more even-looking skin over time.
Lightweight finish — no white cast
Absorbs quickly into a soft, non-greasy finish that layers seamlessly under makeup or alone. Zero white cast on all skin tones — a major reason it's become Korea's go-to everyday SPF.

Quick FAQs

Can this replace my moisturizer?
Yes — for normal to oily skin, the birch sap and hyaluronic acid provide enough daily hydration to skip a separate moisturizer. Dry skin types may still want a cream underneath for extra comfort.
Will it pill under makeup?
No — it's specifically formulated to layer seamlessly. Give it 1–2 minutes to absorb before applying makeup, and it won't peel or ball up under foundation or concealer.
Is it truly reef-safe?
Yes — the formula is free from oxybenzone and octinoxate, the two UV filters most harmful to coral reefs. It uses next-generation filters that are both effective and environmentally responsible.
