RA rays penetrate skin more deeply than either UVA or UVB rays, passing through the epidermis and dermis into the subcutaneous layer. These rays are responsible for the warmth you feel on your skin when you’re out in the sun, but they also generate free radicals that cause collagen breakdown and accelerate skin aging. The heat produced by infrared rays can also lead to inflammation in the skin, which over time plays a role in premature signs of aging.
