The ultraviolet radiation produced by the sun is very abundant in the environment and it affects the skin.
In the past exposure to sunlight stemmed mostly from the need for exposure for professional reasons.
Today the situation has changed and the exposure occurs during leisure activities outdoors or for aesthetic purposes such as at the beach.
In fact, we often come across the fallacy that a tanned skin, as opposed to a lighter one, is healthier.
Actually, when the skin is reached by UV rays, part of them is reflected, another part is dispersed, but, above all, part of them is absorbed in the skin.
UV rays mediate the natural synthesis of vitamin D and endorphins in the skin.
Therefore, they have positive effects for humans, but the side effects are many as well.
Manifestation after exposure to UV rays
Manifestation delayed in time with respect to UV exposure
• DNA photodamage
• Synthesis of vitamin D
Excessive exposure of the skin to ultraviolet rays without protection may result in damage which may be mild, but it may also pose serious health risks.
Exposure to sunlight can cause the onset of skin spots, premature aging of the skin, but also cancer.
