A study published in JAMA showed that 4 chemicals in sunscreens were found in the blood after a single use. These were avobenzone, oxybenzone, octocrylene and ecamsule. What does that mean for you? Should you stop using sunscreen altogether? Absolutely not! Skin cancer is on the rise and it’s very important to protect your skin from ultraviolet light. If you are worried just choose a physical sunscreen with zinc oxide or titanium dioxide. These are totally safe and do not get absorbed into the bloodstream.
