The Science

Why Ethosun?

Say Goodbye to Forever Chemicals.

“Forever chemicals” — known as PFAS (per- and polyfluoroalkyl substances) — are insidious compounds found everywhere, from drinking water and clothing to cosmetics and skincare. They pose serious health risks and are notoriously difficult for the body to eliminate.

Reducing your exposure to PFAS starts with minimizing contact and supporting your body’s natural detoxification systems.

At EthoSun, we’re committed to helping you detox from these harmful chemicals by creating personal care products made with simple, safe, and clean ingredients.

Everyday items like makeup, lotions, shampoos, and sunscreen often contain PFAS. Choosing natural, mineral-based alternatives — like EthoSun’s 100% chemical-free products — is one powerful way to protect your health and the planet.

Choose wisely. Choose clean. Choose EthoSun.

Protection with a Purpose

Here’s why Ethosun stands out as the best choice for a reef-safe, environmentally friendly, and skin-nourishing sunscreen:

1. Truly Reef-Safe Formulation

Ethosun goes beyond standard “reef-safe” labels by ensuring it’s free from all coral-harming chemicals like oxybenzone, octinoxate, and parabens. It’s formulated with ocean-safe minerals and ingredients that won’t harm coral reefs, fish, or other marine life. When you use Ethosun, you’re choosing a product that genuinely respects and preserves marine ecosystems.

2. Superior Skin Protection

Ethosun provides broad-spectrum UVA and UVB protection using mineral-based ingredients like zinc oxide and titanium dioxide, which are effective and gentle on all skin types. With no irritating or harmful chemicals, Ethosun is ideal for sensitive skin, giving you strong sun defense while minimizing the risk of breakouts or skin irritation.
