10 Best Reef Safe Sunscreens 2025 in the United States

The Thrive Reef Safe Sunscreen SPF50 is a commendable choice for those seeking an eco-friendly and effective sun protection option. With a high SPF rating of 50, it provides robust defense against harmful UVA and UVB rays, which is crucial for prolonged outdoor exposure. Its active ingredient, 23.5% non-nano zinc oxide, is known for creating a physical barrier against the sun without the use of chemical filters, making it a safer alternative for both users and marine ecosystems.

One of its standout features is the 80-minute water resistance, ensuring protection during activities like swimming or sweating, though reapplication is necessary for extended exposure. The sunscreen is noted for having a minimal white cast and quicker absorption than traditional mineral sunscreens, which can often be a concern.

Enriched with antioxidants from Costa Rican super-plants, it not only shields but also hydrates and nourishes the skin, potentially soothing irritation and redness. Its commitment to sustainability is evident in its vegan, cruelty-free formulation and the recycled plastic packaging, aligning with environmentally conscious values.

However, individuals looking for a completely invisible sunscreen may still notice some degree of whitening, typical of mineral sunscreens. The scent, described as citrus, might not be to everyone's liking. Furthermore, while the product's commitment to supporting Costa Rican farmers is admirable, consumers primarily focused on sunscreen performance might not prioritize this aspect.

This sunscreen is ideal for environmentally aware consumers who value sustainable skincare solutions and require reliable protection during outdoor activities.

Babo Botanicals Sheer Zinc Continuous Sunscreen Spray SPF30 is a mineral-based, reef-safe sunscreen ideal for those with sensitive skin and families with children. It uses 12% non-nano zinc oxide as its active ingredient, providing broad-spectrum protection against UVA and UVB rays without harmful chemicals like oxybenzone or octinoxate, which can damage coral reefs. The sunscreen offers an SPF of 30, which is a solid level of protection for everyday use. It stands out with its water resistance of up to 80 minutes, making it suitable for swimming or sweating, although reapplication is needed afterward, as with most sunscreens. The spray format is air-powered, which avoids the use of propellants and allows for easy and even application, but users should be cautious not to spray directly on the face or in windy conditions.

Being fragrance-free, vegan, and hypoallergenic, it is gentle enough for babies and adults, reducing the risk of skin irritation or allergic reactions. Additional skin benefits come from organic ingredients like aloe and calendula that soothe and hydrate the skin. The product is also B Corp certified and cruelty-free, reinforcing its commitment to environmental and ethical standards.

This sunscreen requires fairly frequent reapplication, especially after water exposure, and the spray form might need careful handling to avoid inhalation or uneven coverage. It represents a reliable option for anyone wanting a safe, effective, and environmentally friendly sunscreen, particularly suited for sensitive skin and family use.

The Sun Bum Original SPF 50 Sunscreen Body Lotion is a reef-safe option that adheres to the Hawaii 104 Act by being free of Octinoxate and Oxybenzone, which are harmful to coral reefs. Its primary strength lies in its broad-spectrum protection, effectively shielding against both UVA and UVB rays, making it suitable for those looking for high SPF coverage. The sunscreen is also water-resistant for up to 80 minutes, which is beneficial for swimmers or those engaging in outdoor activities.

Moreover, it contains Vitamin E, providing additional moisturizing benefits and is non-comedogenic, meaning it won't clog pores, which is great for people with sensitive or acne-prone skin. Another notable feature is its pleasant 'summer' scent, which many users appreciate. However, the scent might not be appealing to everyone, and those with fragrance sensitivities might want to consider this aspect. Additionally, the lotion form may require more effort to apply evenly compared to sprays or sticks.

Its dermatologically approved formula, free from gluten, parabens, and cruelty, makes it a conscientious choice for consumers. Trusted by beachgoers and designed by people who understand sun exposure, this product stands out for its practical and protective qualities. Frequent reapplication every 2 hours as recommended can be seen as a drawback for those looking for more prolonged, hassle-free protection.
