Sunscreen is essential for protecting your skin from harmful UV rays—but not all sunscreens are created equal. Some may contain ingredients or properties that could do more harm than good. Here are seven reasons why your sunscreen may be unhealthy.
1. It Relies On Oxybenzone
Oxybenzone is a common UV filter linked to hormone disruption, allergic reactions, and potential reproductive toxicity. It’s also harmful to marine life, especially coral reefs. Look for mineral-based alternatives instead.
2. It Touts Fragrance
Many sunscreens include synthetic fragrances and preservatives, which can trigger allergic reactions or disrupt hormone function. Opt for fragrance-free or naturally scented products when possible.
3. It Has Nanoparticles
Mineral sunscreens are generally safer, but if they contain nanoparticles (ultra-small particles of zinc oxide or titanium dioxide), they may cause cellular damage. Choose products labeled “non-nano” to minimize this risk.
4. It's a Spray or Powder Formula
While convenient, spray and powder sunscreens can be inhaled, allowing harmful ingredients to enter your lungs. Cream or lotion-based options are safer and provide more even coverage.
5. It Provides a False Sense of Security
SPFs over 50 may give a false sense of security, encouraging people to stay in the sun too long. They often contain higher concentrations of chemicals, but only offer marginally more protection. Experts recommend using SPF 30–50 and reapplying every two hours.
6. It’s Not Broad Spectrum
A sunscreen that doesn’t protect against both UVA and UVB rays leaves your skin vulnerable to long-term damage like aging and skin cancer. Always look for “broad spectrum” on the label.
7. It’s Expired
Always check the expiration date before use. Using expired sunscreen can significantly reduce its effectiveness. Active ingredients may degrade, and bacterial contamination is also possible.
