Sun Exposure – The Hidden Negative Effects


General Skin Treatment/Skin Protection Information

To help prevent skin damage and maintain skin health, a daily skin care regimen that includes a sun protectant, cleanser, moisturizer or hydrator, and eye cream is a must. It’s also important to incorporate additional specialty products that defend against the signs of aging.

There are two kinds of aging:

  • Chronological aging – what happens naturally due to time and the genes we inherit
  • Environmental aging – due to external factors like sun, pollutants, ozone, smoke, diet, and alcohol
    • The sun is to blame for a significant amount of environmental aging

Incorporating daily protection is an absolute necessity; however, it’s important that women opt for more comprehensive coverage that goes beyond broad spectrum (UVA/UVB) protection to shield against Infrared radiation as well.

There are three kinds of rays from the sun:

  • Ultraviolet
  • Visible Light
  • Infrared

Infrared rays make up 54% of the solar spectrum. Infrared-A rays penetrate deeper into the skin than UVA and UVB rays. IR-A rays can cause signs of aging. They contribute to:

  • Collagen breakdown
  • Skin wrinkling
  • Redness
  • Extracellular matrix changes
  • Loss of skin elasticity and firmness 

Infrared radiation has implications in accelerating the signs of skin aging and has a synergistic negative effect with ultraviolet rays.

How sun exposure affects skin over time:

  • 20’s | Many of the skin changes we see over time – changes in pigmentation, sallowness and deep wrinkling are the results of sun exposure.
  • 30’s | The signs of sun damage may typically begin to emerge on exposed areas of the skin, such as the face, neck, upper chest, hands, and forearms.
  • 40’s | Skin discoloration can also affect people in this age group – a clear sign of “photoaging,” a term that describes the effects of chronic ultraviolet light exposure on the skin.

Exposure to free radicals in the environment, primarily from UV and Infrared rays, can play a pivotal role in the biological events that can lead to clinical manifestations of changes to the skin in this decade, like cell damage.
