Oxybenzone is a long-used UV filter approved under regulatory frameworks developed decades ago. This article examines how newer evidence on systemic absorption, endocrine activity, and high-frequency use has prompted reassessment of earlier safety assumptions, particularly in Australia, where real-world sunscreen use patterns can substantially increase exposure.

Ethylhexyl Triazone is a UVB filter approved under safety frameworks developed decades ago. This article examines whether its continued use can be justified given the absence of modern human exposure data, unresolved impurity and degradation questions, and growing emphasis on cumulative and long-term safety in contemporary regulation.

4-MBC is a UV filter that remains permitted in Australian sunscreens despite being banned or rejected by regulators overseas. This article examines the scientific evidence on systemic absorption and hormone-related effects, and asks why Australia’s regulatory settings differ, particularly given high local sunscreen use and evolving international safety assessments.

Octocrylene is a widely used UV filter in sunscreens, but new scientific evidence has prompted regulatory reassessment. This article examines findings on systemic absorption, degradation into benzophenone, and why Australian sunscreen use patterns raise specific questions about whether existing safety limits remain appropriate under modern standards.

Homosalate is a long-used UV filter in Australian sunscreens, approved at levels set decades ago. New human studies show it is absorbed into the body under real-world use. This article examines why international regulators have re-evaluated its safety, and why Australia’s high-use conditions raise specific questions about current safety margins.

This article outlines how to identify a mineral sunscreen that is both safe and effective, explaining why zinc oxide at sufficient concentrations is essential for UVA protection. It contrasts mineral filters with soluble organic UV filters, which are bioavailable and pose potential risks, and offers evidence-based criteria to guide informed sunscreen selection.

This article explains why soluble organic UV filters may pose health and environmental risks, particularly for children, and reviews evidence that these compounds are widely bioavailable yet provide inadequate UVA protection. It outlines why mineral sunscreens with high zinc oxide content offer safer and more effective photoprotection for families.

This article examines why soluble aromatic UV filters should be avoided during pregnancy, highlighting evidence of systemic absorption, fetal exposure, and potential endocrine and developmental effects. It contrasts these risks with insoluble mineral filters, which do not permeate the skin and offer safer, more balanced photoprotection.

This article examines whether UVB-biased sunscreens may unintentionally increase UVA exposure in a way that resembles tanning bed use. It reviews evidence linking inadequate UVA1 protection to rising skin cancer rates and considers why balanced, broad-spectrum photoprotection is critical for public-health guidance.

This article reviews evidence that many soluble UV filters used in sunscreens become systemically bioavailable and may disrupt hormonal and genetic processes. It discusses why these findings raise concerns for human health and wildlife, and argues for precautionary warnings and the adoption of insoluble UV filters that do not permeate the skin.

This article examines whether sunscreens marketed as “reef safe” or “reef friendly” truly avoid harm to marine ecosystems and human health. It reviews evidence showing that many soluble UV filters permeate living organisms and may disrupt biological systems, highlighting the need for formulations that are safe for both coral and people.

This article reviews emerging FDA concerns that many common sunscreen filters cannot currently be considered safe or effective. It examines evidence of systemic absorption, potential endocrine effects, and the need for precautionary approaches while improved UVA-protective formulations are developed.

This article examines how common sunscreen UV filters used during beach vacations may contribute to coral bleaching and wider marine ecosystem damage. It highlights evidence that these chemicals enter both human bodies and coastal waters, raising questions about safer alternatives and precautionary action.

This article examines common misconceptions about “chemical” versus “mineral” sunscreens and clarifies how UV filters actually function. It challenges popular narratives about naturalness and SPF performance, emphasizing the need for evidence-based distinctions—particularly the role of insoluble filters in providing safer and more effective UVA protection.

This article examines why the SPF label cannot reliably predict safe sun exposure time. It outlines the scientific limitations of SPF testing, the mismatch between laboratory and real-world conditions, and the public-health implications of relying on UVB-biased sunscreens that provide inadequate UVA protection.

This article explores whether soluble UV sunscreen filters are a major everyday source of exposure to endocrine disrupting chemicals. It reviews emerging evidence linking these filters to reproductive and developmental effects and asks how public-health guidance should respond in light of the precautionary principle.

This article examines whether UVB-biased sunscreens may unintentionally increase UVA exposure in a way that resembles tanning bed use. It reviews evidence linking inadequate UVA1 protection to rising skin cancer rates and considers why balanced, broad-spectrum photoprotection is critical for public-health guidance.

This article examines how endocrine disrupting chemicals may affect human health, particularly during vulnerable developmental stages. It questions the reliance on animal data in regulatory decisions and considers whether the precautionary principle should guide public-health responses to everyday chemical exposures.

This article examines oxybenzone, a widely used soluble sunscreen filter, and asks whether its endocrine-disrupting, carcinogenic and ecotoxic properties make it one of the most hazardous routine exposures in modern households, especially for pregnant women, children and coral reef ecosystems.

Industry leaders and union representatives attend the Australian Sunscreen Council’s discussion on SPF testing and sunscreen ingredient safety, led by Dr Yousuf Mohammed and Dr Rocky Chowdhury.
