Shield Your Skin2 min read

When it comes to premature aging, one culprit stands out above the rest: sun exposure. The good news is that there’s a straightforward, daily preventive measure that can significantly reduce the risk of skin cancer and visible signs of aging like wrinkles and sunspots – enter broad-spectrum sunscreen.

Broad-spectrum SPF, or Sun Protection Factor, denotes sunscreens that provide comprehensive protection against both UVA and UVB rays. Even if you’re using a sunscreen with a high SPF rating, it won’t offer complete protection unless it’s broad-spectrum. Currently, the FDA SPF numbering system only quantifies the UVB protection offered by a sunscreen product, leaving out the critical UVA protection aspect. To earn the broad-spectrum label, sunscreen products now have to undergo a series of tests mandated by the FDA to ensure they shield the skin from both UVA and UVB rays.

Understanding the significance of safeguarding against both types of UV rays is essential because they harm your skin in distinct ways:

  • UVB rays, with ‘B’ for “burning,” are responsible for sunburn, premature aging, and the potential for skin cancer.
  • UVA rays, with ‘A’ for “aging,” contribute to the formation of wrinkles and, after repeated exposure, a risk of skin cancer (though less than UVB). Surprisingly, UVA rays constitute over 90% of all UV radiation, penetrating clouds and glass throughout the year.

Broad-spectrum sunscreens contain carefully selected ingredients that offer protection against both UVA and UVB rays. Look out for a combination of zinc oxide, octinoxate, octisalate, and titanium dioxide. Different combinations of these ingredients provide comprehensive protection against both UVA and UVB rays, ensuring your skin’s safety.

Making broad-spectrum protection a daily habit is the key to maintaining healthy skin and preventing premature aging, including fine lines, wrinkles, and sunspots. It’s also a crucial step in guarding against certain types of skin cancers. If you’re limited to just one skincare product before stepping out, make it a broad-spectrum sunscreen. Your skin will thank you for it.
