Too much UV radiation causes your skin to age
Too much UV radiation accelerates the aging of your skin. Even if you want a tanned complexion, you should therefore pay attention to a sufficient UV protection when sunbathing. Especially with a light skin type, caution is required.
This is how UV radiation works
If you take a bath in the sun, then three different types of UV radiation hit your skin. The UVA radiation reaches the middle skin and ensures a relatively fast tanning. UVB light penetrates less deeply into the skin and acts in particular on the epidermis. Here it is responsible for the longer-lasting tan. There are also infrared A rays that make up about 30 percent of sunlight. These rays can penetrate deep into the subcutaneous tissue and cause collagen degradation there. The result is often a visible relaxation and thus premature aging of the skin.
The dangers of sunbathing
Too much UV radiation can pose a threat to the skin in several ways. Aging is only part of the problem. More dangerous is the conversion of oxygen molecules into free radicals, which is promoted by UVA radiation. The result may ultimately be damage in the reproductive program of the cells. Their self-protection function is largely turned off, which can lead to sunburn and permanent damage.
The right protection for your skin
In order to prevent premature skin aging and damage of all kinds, sufficient sun protection is of great importance. The UV radiation is usually most intense between 10 and 14 o’clock. During these hours, you should avoid the sun as much as possible. Otherwise: Use sunscreen with adequate SPF. In the first days it should be a factor of 25 to 30. After a certain habituation of the skin to the sun you can reduce the factor to 15 to 20. Special care must be taken by people with fair skin. They are more susceptible to skin damage from UV radiation.
