Did you ever wonder why skin cancer is on the rise despite people generally getting less sun exposure?
There are no hard rules, but there are concerns regarding many sunscreens and their ingredients.
There are two different types of sunscreen technology: mineral and chemical.
Mineral sunscreens(zinc oxide and titanium dioxide) sit on top of the skin and block UV rays. They are generally recognized by the FDA as safe and effective.
Chemical sunscreens(oxybenzone, avobenzone, octinoxate, octisalate, homosalate, and others) absorbinto the skin and convert UV radiation into heat.
Studies have shown that some chemical sunscreen ingredients can also be absorbed into the bloodstream. While this does not necessarily mean they are harmful, it has raised questions and prompted additional research into their long-term safety.
Two ingredients that have received the most scrutiny are oxybenzone and octinoxate. Concerns have been raised about their potential hormone-related effects, as well as their impact on coral reefs and the environment. Because of these concerns, products containing these ingredients have been restricted or banned in some regions.
"Sunscreen doping" is a real labeling loophole. Be cautious of mineral sunscreens that quietly add chemical sunscreen ingredients because they may still be marketed primarily as mineral sunscreens. Read the ingredient list—not just the front label.
Also, the bottom line is to avoid spray sunscreens because of the added chemicals and the potential inhalation risks.
There are certainly risks associated with unprotected sun exposure, including premature skin aging. However, completely avoiding the sun and its many benefits can also be problematic.
The Bottom Line:
