How the Skin Changes with Exposure to Sunlight

SunlightSunlight is important to the skin as it helps create vitamin D, an important nutrient for normal bone formation, however, the ultraviolet rays are detrimental to health.

Long exposure to ultraviolet rays may lead to eye problems, premature aging, wrinkles and various types of skin disease.

Different Types of Ultraviolet Rays

The three different types of UV rays (UVA, UVB, and UVC) fall into categories depending on their wavelength. They differ in their activity and the degree to which they enter the skin. Rays that have a shorter wavelength are more harmful than longer ones. Shorter wavelengths have less capacity to penetrate your skin.

UVC has the shortest wavelength and is also the most damaging type of radiation, but it does not reach the earth’s surface because the atmosphere filters it.

Medium-wavelength UVB is biologically active, however it cannot enter beyond the superficial layers of your skin. These rays are responsible for delayed burning and tanning, premature aging and may lead to the likelihood of developing skin cancer.

The long-wavelength UVA is responsible for around 95% of the radiation that reaches the earth’s surface. It can enter deep into the layers of your skin, and leads to the immediate tanning effect, wrinkling and premature skin aging.

These three wavelengths have varying effects on the skin. Avoid overexposure by using sunscreen and the installation of blinds to prevent excessive sunlight into your property.

Effects of Overexposure to Sunlight

Cedar Blinds Specialists agrees that overexposure to sunlight triggers skin changes that may seem healthy, but may actually lead to:

  • Coarse and fine wrinkles
  • Benign tumours
  • Pre-cancerous skin lesions
  • Sallowness, a discolouration of the skin
  • Elastosis, the destruction of collagen and elastic tissue
  • Skin cancer

These are some of the negative effects of long exposure to harmful UV rays. Just because you stay indoors most of the time does not mean you escape radiation. Install blinds or stay away from windows to avoid overexposure to sunlight at home or in the office.
