Sunscreen Chemicals

DID YOU KNOW?

Four studies published in 2020 found that the chemical oxybenzone may increase the risk of breast cancer due to its hormone-disrupting effects. [1] Sunscreen is essential — but the type you use matters.

KNOW THE RISK

  • Sunscreen is intended to be applied every day and over large areas of the body, including the face, shoulders, and back. This increases potential exposure to its active ingredients.
  • In 2019, the FDA found that only two ingredients — zinc oxide and titanium dioxide — are generally recognized as safe and effective (GRASE). [1]
  • Other common sunscreen ingredients like oxybenzone and octinoxate have been linked to endocrine disruption, which can interfere with hormone regulation. [1]
  • These chemicals can be absorbed into the bloodstream within hours of application, even after a single use, and may persist for days. [1]

MITIGATE THE RISK

1. Choose Mineral-Based Sunscreens

  • Select sunscreens that use non-nano zinc oxide or titanium dioxide. These ingredients sit on the skin’s surface and reflect UV rays without penetrating the skin. [1]

2. Avoid Spray-On Sunscreens

  • Sprays can release titanium dioxide or other particles into the lungs if inhaled. Use creams or lotions instead for better control and coverage. [1]

3. Read the Label Carefully

  • Even among mineral sunscreens, check for added fragrances, preservatives, and nano-particles. Simpler is safer. [1]

SUN SAFETY REMINDER

UV protection is non-negotiable — but your sunscreen shouldn’t introduce new health risks. Opt for mineral-based sunscreens with clean ingredients, especially for daily use and on children. Protect your skin and your long-term health at the same time.
