SunDay Mineral Serum SPF 50+

Suncare as skincare. 

Rich broad-spectrum protection with non-nano zinc oxide that blocks 98% of UV. This fluid serum has a protective, nourishing feel and soft-matte grip that holds up through sweat and water. Ideal for active days, prolonged exposure, sun-sensitive skin, and under makeup.

Key Benefits:

• Broad-spectrum protection with non-nano zinc oxide
• Skin-strengthening niacinamide builds resilience, reduces redness, and reinforces your skin’s natural barrier
• Soothing allantoin and bisabolol calm sensitivity while reducing redness
• Water- and sweat-resistant for up to 80 minutes
• Fluid serum texture feels rich and protective on skin with a grippy, soft-matte finish that’s perfect for layering

How to Use: 

Shake well before use. Apply 15 minutes before sun exposure. Rub in thoroughly (mineral SPF takes a few extra seconds to fully absorb). Reapply every two hours, or after 80 minutes of swimming or sweating. Best as the final step in your skincare routine. Allow to fully set before applying makeup.
