Description

A. About the Product

The Round Lab Birch Juice Mild-Up Sunscreen 50 ml is a hydrating physical (mineral) sunscreen formulated for sensitive skin. It uses zinc oxide as its active UV filter and combines birch sap, hyaluronic acid, and botanical extracts to deliver hydration, soothing care, and broad-spectrum protection—all in a lightweight, refreshing formula. 
It also functions as a moisturizing “skin care + sun care” step, designed to prevent dryness and maintain a smooth barrier under sun exposure.

• Zinc Oxide (17 %) — physical sunscreen filter offering broad UV protection (SPF 50+, PA++++) Birch Sap (Betula Platyphylla Japonica Juice) — hydrates, soothes, and supplies minerals & amino acids
