Inexhaustible source of energy and life, the sun is related with the most carefree and happy time of year, the summer. Without overlooking the unique benefits of sunshine for the overall well-being, provided a rational and controlled sun exposure, we need to emphasize that the sun poses several risks in cases of prolonged exposure. The most common effect of solar radiation on the skin is redness.

However, excessive and chronic exposure may have serious health effects, e.g., premature skin aging, even skin cancer. Depending on skin type and other factors, the exposure time, in which ultraviolet radiation can cause the serious aforementioned situations, differs from one person to another.


UVA radiation penetrates deeper into the skin than UVB, while its action is continuous throughout the day and year. The UVA rays are responsible for premature skin aging, while long-term exposure -especially since childhood – can lead to skin cancer.

UVB radiation is most intense during summer months, with the intensity peaking during early afternoon. UVB radiation is responsible for burns and rashes on the skin caused by sun exposure. Chronic exposure to this type of ultraviolet radiation can also lead to skin cancer.

UVC radiation is the most threatening kind. However, it is absorbed by the ozone layers and thus does not reach the earth’s surface.


Visible light is defined as the wavelengths that are visible to most human eyes. In other words, it comprises all the colors that a human sees with the naked eye. It is connected to oxidative stress and persistent hyper pigmentation.


Infrared radiation is invisible to the eye, it can be detected as a sensaion of warmth on the skin.


The skin is a vital organ of the human body, as it protects all the internal organs from the external environment. The outer layer of skin is the epidermis, below which lies the corium, the inner skin layer. A very important skin function is protecting the body from the harmful effects of UV radiation through melanin, a pigment produced by melanocytes.
Τhe skin is also involved in a process of great importance for the good health of the human organism: the formation of vitamin D.
