Round Lab Birch Mild-Up Sunscreen UVLock SPF 50+ Broad Spectrum 50ml/1.69oz

Round Lab Birch Mild‑Up Sunscreen UVLock SPF 50+ (50 ml / 1.69 oz)

This mineral sunscreen from Round Lab is specially formulated for sensitive, irritated or barrier‑weakened skin. Featuring birch sap extract and high‑level UV protection, it offers a soothing, hydrating finish with broad‑spectrum defence.

Benefits

• Provides broad‑spectrum protection with SPF 50+ and PA++++, helping shield skin from both UVB and UVA damage. 

• Formulated with birch tree sap (from silver birch / Betula species) rich in minerals, enzymes and amino acids to soothe and hydrate the skin barrier. 

• Uses non‑nano mineral filters (zinc oxide, and possibly titanium dioxide) for a gentler, physical form of UV protection suitable for many sensitive or reactive skin types. 

• Lightweight, non‑greasy texture with a soft finish; many users note minimal white cast and comfortable wear under makeup. 

• Reef‑safe / ocean‑friendly formulation and free of a number of harsh irritants—making it a cleaner choice in sun‑care. 

How to Use

1. As the final step of your morning skincare routine (after cleanser, toner, serum, moisturizer), apply a generous, even layer of the sunscreen to face and neck. 

2. Spread evenly and ensure full coverage—pay attention to edges like hairline, ears and neck.

3. Re‑apply every 2 hours when exposed to sun, and after swimming, sweating or towel‑drying. 

4. At night, remove thoroughly using a cleanser to ensure no residue remains.

5. Use daily—even when indoors or on cloudy days—as UV exposure accumulates over time.
