Waterproof Mineral Sunscreen

Stay protected no matter where your adventures take you with our Waterproof Mineral Sunscreen collection—designed for outdoor lovers who care deeply about their skin and the ocean. Powered by non-nano zinc oxide, these sunscreens offer broad-spectrum SPF protection that’s both water-resistant and reef-safe.

Perfect for long beach days, snorkeling, paddling, hiking, or just soaking in the sun, each formula is biodegradable, ocean-friendly, and sweat-resistant, so you never have to worry about reapplying after every splash. Free from harsh chemicals like oxybenzone, octinoxate, and parabens, these sunscreens are also enriched with skin-soothing botanicals like green tea, aloe, and wakame to nourish and protect even the most sensitive skin.

With no white cast and a lightweight, non-greasy feel, they glide on easily and stay on strong—making them a favorite for anyone who needs high-performance sun care that lasts through water and activity.

Every sunscreen in this collection reflects Stream2Sea’s unwavering commitment to clean, effective ingredients and ocean preservation.

High-performance sun care that’s safe for your skin—and the sea.
