An estimated 14,000 tons of sunscreen enter oceans annually, contributing to coral bleaching and marine toxicity. Mineral sunscreens, made with zinc oxide and titanium dioxide, reflect UV rays and provide benefits like controlling shine and sensitivity. While mineral options are generally viewed as safer for oceans, the term "reef-safe" is unregulated, and the impact of nano-sized particles in these sunscreens on coral and marine life remains a concern. Regulatory bans on harmful chemical filters are increasing, emphasizing the need for ethical consumer choices in sunscreen selection.
Every year, an estimated 14,000 tons of sunscreen wash off swimmers and sunbathers into the oceans - much of it containing chemical UV filters linked to coral bleaching and marine toxicity.
Mineral sunscreens use active ingredients like zinc oxide and titanium dioxide to sit on the surface of your skin and reflect the sun's rays.
Many traditional chemical UV filters, like oxybenzone and octinoxate, have been shown to contribute to coral bleaching and DNA damage in marine life.
Mineral sunscreens are generally seen as less harmful, but there's a caveat: it depends on the particle size, as nano-sized particles can still be absorbed by marine organisms.
