FAQ

While “reef-safe” isn’t officially regulated, Sun Matters formulas follow standards like Hawaii Act 104, which bans oxybenzone and octinoxate. All our products meet these guidelines.

At Sun Matters we use second-generation modern European UV filters that are specifically selected for their high performance, stability, and skin compatibility. These advanced filters provide strong, broad-spectrum protection against both UVA (aging) and UVB (burning) rays, while being gentler on sensitive skin compared to older sunscreen filters.

We pair these UV filters with skin-supporting ingredients like hydrators and plant-derived components to create formulas that feel lightweight, comfortable, and effective for everyday wear.
