Sunscreen Safety: What You Need to Know
Summary
A recent study has raised concerns about the safety of some chemicals in sunscreens, as they can penetrate the skin and enter the bloodstream. However, dermatologist Kanade Shinka assures that sunscreen is still essential in protecting the skin from the sun. The article recommends the use of mineral-based sunscreens, which have been tested and proven to be safe. The FDA has proposed that sunscreen companies provide safety testing, and manufacturers will be required to test their products for systemic absorption and toxicity. Ultimately, it is crucial to protect the skin from the sun through various means, including sunscreen, protective clothing, and avoiding direct sun exposure.

The Study: Penetration of Sunscreen Chemicals into the Bloodstream
A recent study has shown that some chemicals in sunscreens can penetrate the skin and enter the bloodstream at levels higher than the regulatory threshold. The study looked at four commercially available formulations of sunscreen and found notable absorption of sunscreen ingredients. The chemicals in mineral sunscreens, zinc oxide and titanium dioxide, have been tested and found to be safe, whereas the safety of the chemicals in chemical sunscreens is unknown.
Chemical vs. Mineral Sunscreens: Safety and Effectiveness
The article discusses the safety and effectiveness of chemical sunscreens, which have not been subjected to safety testing in humans despite some studies suggesting changes in hormone levels and reproduction. The study recommends the use of mineral-based sunscreens, which have been tested and proven to be safe. However, the effective dosage of sunscreen is still under investigation, and the study discussed in the article was conducted under idealized conditions.
The Role of Behavioral Psychology in Sunscreen Usage
The effectiveness and safety of sunscreen have been a topic of concern. Studies have shown that people often apply less sunscreen than recommended, leading to inadequate protection. The FDA has proposed that sunscreen companies provide safety testing, and manufacturers will be required to test their products for systemic absorption and toxicity. If they fail to provide the data, their products could be pulled from the market.
Conclusion
While concerns have been raised about the safety of some chemicals in sunscreens, it is important to note that the danger of sun exposure is well-established, and sunscreen remains an important tool for protection. People can choose mineral sunscreens if they have concerns about the chemicals in regular sunscreens. Ultimately, it is crucial to protect the skin from the sun through various means, including sunscreen, protective clothing, and avoiding direct sun exposure. Behavioral psychology can also play a role in promoting proper sunscreen usage.
