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.
