Korean sunscreen powered by Birch Tree Sap — rich in minerals, enzymes, and antioxidants. SPF 50+ PA++++ broad spectrum protection that hydrates, brightens, and soothes your skin all day.
Why You Need This
Most sunscreens leave skin dry and chalky. ROUND LAB's Birch Juice formula protects while keeping your skin moisturized and glowing.
Daily UV exposure causes premature aging and dark spots. SPF 50+ PA++++ provides maximum broad-spectrum protection against UVA and UVB rays.
Many sunscreens strip moisture and leave a white cast. Birch tree sap locks in hydration while forming a protective barrier against dryness.
Niacinamide and birch juice work together to brighten skin and even out tone, giving you a natural glow under sun protection.
Perfect For
A soft, creamy sunscreen that fits seamlessly into any routine — from morning commute to outdoor adventures.
Apply as the last step of your AM routine. The creamy texture absorbs quickly and layers beautifully under makeup.
SPF 50+ PA++++ keeps you protected during extended sun exposure. Reapply every 2 hours for continuous defense.
Blue light and UV rays penetrate windows. This lightweight formula protects without feeling heavy during long work days.
The 50ml size is travel-friendly and TSA-approved. Stay protected wherever your adventures take you.

Get the most out of your purchase with these practical tips
Apply two finger-lengths of sunscreen for full face and neck coverage. Most people under-apply, reducing actual SPF protection.
Set a timer when outdoors. Reapply immediately after swimming, sweating, or towel-drying — even with water-resistant formulas.
Apply sunscreen as the LAST step of skincare, BEFORE makeup. Wait 1-2 minutes for it to set before applying primer or foundation.
Sunscreen loses effectiveness after expiration. Most products are good for 12 months after opening. Write the open date on the bottle.
See how it stacks up against similar products in its category.
The lotion version is lighter and absorbs faster — ideal for oily or combination skin. The Sun Cream is richer and more emollient, better for dry skin. Both offer the same birch juice hydration and SPF50 protection.
