We are constantly bombarded with news about the damaging effects of the sun. Most of the information is about ultraviolet (UV) radiation. Traditional sunscreens block UV radiation, but newer research has shown that infrared (IR) can be just as damaging, especially as it relates to anti-aging. Our newest sunscreen from SkinMedica, Total Defense and Repair, now blocks UV and IR. In addition, it incorporates products to reverse aging by using antioxidants to neutralize free radicals produced from prolonged sun exposure.

In the past, we did not have significant levels of IR reaching the earth’s surface due to a more robust ozone layer. Now, scientists have shown an increase in the IR levels. In addition, IR exposure is more significant the further north you are. With a more mobile society, protecting yourself from IR has become a must. When you are exposed to solar IR radiation, it will be converted to heat once it penetrates your skin. Studies have shown that the skin can reach temperatures as high as 40C. When you are exposed to IR repetitively, changes will occur in your skin such as wrinkling. This occurs due to the breakdown of collagen. Also, chronic IR exposure will lead to the formation of tiny red blood vessels in your skin. There is also research that has shown that IR can induce DNA damage in your skin cells, which may lead to increased risk of skin cancer.
