While there are instances where sunscreen may be prudent, these products are widely overused and contribute to widespread vitamin D deficiency. In my view, sunscreen is rarely needed, provided you’re following sensible sun exposure guidelines to prevent burning. Simply get out of the sun or wear clothing the moment your skin starts to turn light pink. A pilot study by the U.S. Food and Drug Administration (FDA) shows four commonly used active ingredients in sunscreen are absorbed into your blood at levels that could potentially pose health risks. The four active ingredients looked in this study were avobenzone, oxybenzone, octocrylene and ecamsule. While it comes as no surprise that toxic chemicals are being absorbed into your blood when applied to your skin, what’s shocking is the FDA’s guidance in light of the results — continue using sunscreen! This, despite the fact that all four chemicals were found to enter the bloodstream at levels above the presumed “safe” level after a single day of application, and remained in the system for at least 24 hours after last use. Just what might the ramifications be if you’re using them every single day, year-round?
