As a lifelong tennis player, Venus Williams always used sunscreen but struggled to find an eco-friendly option that blended seamlessly into her dark skin. So, she created her own formula.   EleVen by Venus in partnership with Credo recently dropped two new mineral sunscreens—the On-The-Defense Sunscreen SPF 30, a more traditional cream that has zero white cast and a semi-matte finish (ideal for oily skin), and the Unrivaled Sun Serum SPF 35, a lighter formula complemented by hydrating ingredients.   The active ingredient in both is zinc oxide, which is safer for the ocean’s coral reefs compared to chemical formulas, according to the National Park Service. The Park Service reports that chemical sunscreens can actually awaken coral viruses, causing the reefs to become sick, expel their algae, and die. “As an athlete and professional tennis player spending most of my life outdoors, I was compelled to create a sun care collection I could use daily,” Williams shared in a statement, per InStyle. “Safe for our planet and good for people of all skin shades and types, I hope to inspire others to get out, be active, and stay healthy.”   Just like the environmentally-friendly ingredients, Venus chose recyclable and sustainable packaging. The Unrivaled Sun Serum bottle is made of recyclable glass, and the On-The-Defense sunscreen tube is made of 40% post-consumer recycled materials and can be recycled again through Credo’s TerraCycle program. Both products are vegan and cruelty-free.   The product line hasn’t been available for long, but it has already garnered some positive feedback. “I was hooked after my first day wearing it,” one reviewer said of the sun serum on Credo’s website. “Goes on so light doesn’t leave and residue on my skin at all.” Another reviewer raved about the sunscreen: “This has a beautiful matte finish, and very moisturizing to my dry skin. I also love how this is fragrance free, as I have allergic dermatitis.” We're sold!
