Simply put, photoaging is the skin damage caused by extended periods of sun exposure. This is an important topic because with prolonged exposure to the sun such as UVA and UVB rays, it can cause skin cancer! UV radiation damages many important proteins that help prevent cancer, and these proteins include collagen, elastin, and other fibers. Today we’re going to discuss the dangers, symptoms, and prevention measures of photoaging.
Let’s discuss those important skin proteins a little bit more to further understand the severity of photoaging. So, let me break it down. The skin is composed of three layers: the epidermis, dermis, and subcutaneous tissue. The second layer, the dermis, is the layer filled with collagen, elastin, and those other skin-saving proteins. If these proteins aren’t sufficiently present, the skin will start to lose its buoyancy and youthful appearance. The loss of these proteins is a common sign of photoaging. So, what all can cause this to happen?
We’ve already mentioned that it is caused by UV radiation, but there are some rays that can be more of a danger than others. UVB rays burn the skin, which usually results in a sunburn. UVA rays, however, actually age the skin. Why? UVA rays have longer wavelengths than UVB rays, and therefore they can damage the dermis much easier and deeper. We’re exposed to UVA rays almost daily, so there is definitely a need to take precautions where we can to prevent some damage.
