Birch Mild-Up Sunscreen UVLock SPF 50+ Broad Spectrum

For mineral SPF on sensitive skin

The Mineral Guard for Sensitive Skin

While the original Birch Juice Sunscreen is a global phenomenon, the "Mild-Up" version is specifically formulated with non-nano Zinc Oxide for those who prefer a 100% mineral shield. It utilizes the same hydrating Birch Sap from Inje to ensure the skin stays moisturized without the typical dryness of mineral filters.

Why it’s a Real Gem: It is "Loved by Locals" who have hyper-reactive skin. It provides a physical barrier against UV rays while maintaining a surprisingly smooth, non-ghostly finish for a mineral SPF.

Best For: Children, pregnant women, or those with highly sensitive skin who need a "Safe and Proven" mineral sunscreen.

Key Ingredients
Zinc Helps care for sensitive skin by supporting sebum balance and skin comfort. Beta Hyaluronic Acid Provides hydration and helps boost skin vitality for a fresh, moisturized feel.
How to Use
Apply evenly as the final step of your morning routine. Use approximately two finger lengths for face and neck. Reapply every 2–3 hours when exposed to sunlight. When: AM. Actives tip: Apply after skincare has fully absorbed.
