Kallgren Dermatology in Boulder knows you enjoy the outdoor lifestyle that Colorado is known for. This lifestyle can mean that you are exposing yourself to a dangerous level of UVA and UVB rays that can damage your skin and lead to skin cancer. If you don’t take appropriate precautions, you may end up paying the price with your looks and good health. This blog series is addressing some common misconceptions about sun exposure. Among the topics we’ve covered are UV rays and car windows and the perceived protection shade gives you. To learn more about some misconceptions, and the truth behind them, keep reading.

You Can Have a Healthy Tan

  • It’s the UVB rays of the sun that cause tanning. When they hit the skin, they induce the production of melanin, or the skin pigment of a tan, according to Wikipedia. The process that produces melanin also forms lesions, called pyrimidine dimers, on the affected strands of DNA. While the body frequently repairs these lesions with no errors, when errors or gaps occur, it can lead to the formation of melanomas. While it is true that a tan does give the skin minor protection from the sun, it’s only equivalent to an SPF 3 sunscreen.

UVA Rays

  • If it was just the UVB rays that you had to worry about, a suntan might not give you too much concern, but UVB rays always come with UVA rays, and these rays are the ultraviolet rays responsible for the visible signs of aging in your skin.

To avoid long-term damage and premature signs of aging, take care of your skin by avoiding the sun during peak hours, cover up, and always use a broad spectrum sunscreen. Call Kallgren Dermatology for your annual skin check.
