Mineral Protection That Feels Like Skincare

This matte finish sunscreen serum settles into skin like a second layer — fluid, weightless, and quietly protective, leaving a soft-matte finish that holds through heat, movement, and long days in the sun. SunDay SPF 50+ by SONNI is mineral protection that finally feels like skincare.

Why Your Skin Will Love It

• Crafted with smarter zinc — non-nano zinc oxide at 12% delivers serious broad-spectrum SPF 50+ protection without the heavy cast or residue mineral formulas are known for.
• Barrier-strengthening niacinamide works beneath the surface to reduce visible redness, improve tone, and reinforce your skin's natural resilience over time.
• Soothing allantoin and bisabolol calm sensitivity and support post-sun recovery, making this ideal for reactive and sun-sensitive skin.
• 80-minute water and sweat resistance keeps protection intact through active, outdoor days — formulated to hold up without reapplying every hour.
• Fluid serum texture absorbs cleanly and layers seamlessly under makeup, with a soft-matte grip that never feels heavy or occlusive.
• Vegan, cruelty-free, and reef-safe — free from parabens, fragrance, and chemical UV filters, made with a commitment to your skin and the world around it.
• 2026 Men's Health Grooming Award Winner — named Best Sunscreen Serum for lightweight, innovative SPF protection up to 80 minutes during workouts, on land or in water.

When you're ready to protect your skin without compromise, this clear sunscreen with botanical skincare ingredients is the perfect start.
