UV Skinz's CEO and Founder Rhonda Sparks Talks About the Dangers of UV Radiation

I have a complex relationship with the sun, as do most of us who are aware of what too much-unprotected sun exposure can do to our bodies. While it can feel warm and comforting, unprotected sun exposure can damage your skin and lead to skin cancer over time.

Because of this, it is important to understand what UV rays are, how they affect us, and how we can live sun-safe alongside them, which is what we're going to go over today. 

What Are the Three Types of UV Radiation?

There are 3 types of UV radiation, UVA, UVB, and UVC.

While UVC is the most damaging UV ray, it is completely filtered by the atmosphere and does not reach the earth’s surface.

The rays you need to worry about are UVA and UVB. Both UVA and UVB penetrate the basal layer of the epidermis–where most skin cancers occur–and play an important role in conditions like premature skin aging, eye damage (including cataracts), basal cell carcinoma, and even melanoma.

UV radiation is invisible to the naked eye, making it easy to forget to be aware of its presence. Here are some facts about UVA and UVB rays you should know about:

UVA Rays

  • UVA rays account for 95% of the UV radiation that reaches the earth’s surface.
  • Although less powerful than UVB rays, UVA rays are 30-50 times more prevalent.
  • UVA radiation is the dominant tanning ray (a tan is a direct result of injury to our skin’s DNA).
  • UVA radiation has been linked to premature aging, wrinkles, and sunspots.

UVB Rays

  • UVB radiation, also known as the “burning rays” are the chief cause of sunburns.
  • UVB rays play a role in the development of skin cancer, as well as suppression of the immune system.
  • A positive effect of UVB exposure is that it prompts the making of vitamin D. Another way to receive Vitamin D naturally without the risk of sun damage is through eating foods such as salmon, trout, tuna, fortified milk, and certain mushrooms.
  • The most significant amount of UVB rays hit the United States from April to October between 10 AM and 4 PM (although you can develop damage year-round).
