The effect of UV on skin


The sun has a beneficial effect on our well-being, but does it have an equally positive effect on our skin?

UV rays constitute only 5% of the sun's rays that reach the ground, but they are very strong and have a significant impact on our skin.

There are several types of ultraviolet radiation:

UVC - mostly absorbed by the ozone layer

UVB - represents 5% of ultraviolet radiation reaching our planet's surface. It is absorbed by clouds and glass. The intensity of this type of radiation depends on the season and time of day - the strongest is during the summer between 10 a.m. and 3 p.m. It is absorbed only by the outer layers of the skin, i.e. the epidermis. It contributes to the formation of vitamin D. It is responsible for the tan, but also for the formation of erythema and sunburn.

UVA - represents 95% of ultraviolet radiation reaching our planet's surface. It penetrates window panes, clouds and thin clothing. We are exposed to this radiation all year long. This radiation penetrates deep into the skin and can damage cells without causing pain symptoms. To some extent, it contributes to the formation of a tan, but is also responsible for photo-aging, allergic reactions and the formation of skin cancer. Note this type of radiation is emitted by lamps in indoor tanning.
