The sun is a vital source of energy that not only provides warmth and light but also promotes well-being. However, sunlight, especially ultraviolet (UV) rays, also poses risks to our skin. In this blog post, we explain how different UV rays affect the skin and why an effective sun protection is important all year round.

The effect of UV rays on the skin

UVA rays: This is why they cause skin aging

UVA rays penetrate deep into the skin and are significantly responsible for premature skin aging. They even penetrate glass windows and can therefore play a role not only outdoors but also indoors. UVA rays promote the formation of free radicals, which can lead to damage to cell structures. This often manifests in the form of wrinkle formation and a decrease in skin elasticity.

UVB rays: This is how they cause sunburn

UVB rays are the main cause of sunburn. They damage the upper layers of the skin and play a crucial role in the development of skin cancer. UVB rays are particularly intense during the summer months and at midday when sunlight is strongest. They are less penetrating than UVA rays, but more aggressive in their effect on the skin.

The necessity of year-round sun protection

Many people think that sunscreen is only necessary in summer or on vacation at the beach. However, we are actually exposed to UV rays all year round. Even on cloudy days, up to 80% of UV rays can reach the Earth's surface. Even in winter, UVB rays, especially in combination with snow that reflects up to 80% of the rays, can lead to sunburn.

A good sun protection is therefore essential to protect the skin from the harmful effects of UV rays. This includes using sunscreen with a high sun protection factor, which should be applied regularly. Additionally, it is advisable to wear protective clothing and to avoid direct sunlight during the most intense hours of the day.

In conclusion, it can be said that a conscious approach to sunlight and the use of sunscreen not only serves aesthetic skin care but also makes an important contribution to the prevention of skin diseases. Take sun protection seriously – your skin will thank you.
