The Top 5 Sunscreen Myths
The Difference Between Chemical and Mineral Sunscreens
The 5 Biggest Sunscreen Myths - As Told By A Dermatologist
SPF is extremely misleading, and you should never select a sunscreen based on SPF.
Check the back and check the active ingredients - it is the best way to determine the strength and safety of a sunscreen. Mineral sunscreens are safe and more stable, whereas chemical sunscreens can often be dangerous.
How To Select A Sunscreen - According to the American Academy of Dermatology
Mineral (Physical) Sunscreen Filters are Zinc Oxide and Titanium Dioxide, which reflect UV radiation. Mineral filters are safe for babies, sensitive skin, and coral reef safe.
Chemical Filters absorb a small range of UV radiation, causing a chemical reaction on your skin. Often times, chemical filters cause hormonal disruptions and allergic reactions.
How Do UV Rays Affect Us?
Use a broad spectrum sunscreen SPF 30-50 and make sure it is water resistant.
Why Broad Spectrum Matters
The difference between UVA, UVB, and UVC rays and how they affect us. UVA rays penetrate deep within the skin, causing aging and tanning. UVB rays cause burning.
Who Regulates Sunscreens?
A sunscreen with only a SPF rating and no broad spectrum means that you are only protected from the UVB (burning) rays, and not the UVA (aging and tanning rays)
How Do We Protect From UVA and UVB Rays?
In the United States, sunscreen is regulated by the FDA, and classified as being an Over The Counter (OTC) Drug.
What Does SPF Really Stand For?
To protect against both UVA and UVB rays, make sure you choose a broad spectrum sunscreen, and other measures of sun protection such as sun protective clothing, hats, sunglasses, and seek shade.
What is the difference between UVA and UVB rays?
SPF (Sun Protection Factor) only represents the protection from UVB (burning) rays. NOT UVA (aging and tanning rays)
