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. Formulated without 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.
