• Understanding UV radiation and its effects


    According to dermatologist Dr. Liz Casintahan, skin damage is caused by daily exposure to solar radiation, which permeates the skin all the way down to the cells and DNA. Daily sun damage causes sunburn and inflammation visible on the superficial layer of the skin. However, constant exposure triggers molecular responses that cause cell damage, skin aging, and DNA lesions that can lead to skin cancer.

    The three main types of radiation that damage the skin are UVA and UVB which come from the sun, and infrared rays (IR) coming from heat and thermal radiation, found indoors. These three “ invisible” wavelengths penetrate the skin and cause damage to skin cells and its DNA.
