Photoaging: Skin aging due to UV rays

Photoaging: Skin aging due to UV rays

The sun’s UV radiation is one of the most serious environmental influences on our skin, because in addition to the tan that is perceived as beautiful, it also causes premature skin ageing (photoaging). In addition to increased wrinkles and sagging skin, sun damage can also cause hyperpigmentation and, in the worst case, skin cancer. So if you want to enjoy healthy and beautiful smooth skin for as long as possible, you should start early on to reduce the effects of skin aging. Remember: UVA rays also penetrate clouds and glass panes. They therefore stress the skin throughout the year, so daily sun protection is recommended.

Signs and symptoms: How UV radiation damages your skin

The effects of UV radiation include direct DNA damage and the formation of free radicals. The visible consequences can range from premature skin aging to skin cancer. As the face, hands and décolleté are more exposed to harmful rays than the rest of the body, these areas – especially the face – require careful care and constant protection all year round.

Typical signs of premature skin aging are

  • coarse folds
  • sagging skin texture
  • uneven coloring
  • Light callosity

UVA rays penetrate deep into the lower skin layers and can damage the skin in the short and long term.

Causes and triggers: Photoaging: Skin aging due to UV radiation

With increasing age the skin changes:

  • The amount of collagen and elastane in the skin decreases, the skin loses volume and elasticity and fine lines and wrinkles develop.
  • The skin loses its ability to store sufficient moisture and the body’s own production of natural moisturizing factors decreases. The skin becomes drier.
  • Uneven pigmentation may occur, such as dark spots called hyperpigmentation. Forms of this are age spots and sunspots.

As the skin ages, it loses its elasticity.


The causes of premature skin aging can be divided into two areas: internal (intrinsic, genetic) and external (extrinsic, environmental) factors:

  • Internal skin aging:This type of aging is completely natural and we have no influence on it. Intrinsic ageing is caused by internal factors such as genetics, ethnic origin and the hormonal changes in the different phases of life.
  • External skin ageing:External ageing, on the other hand, is controllable. Extrinsic ageing is caused by external factors such as

The extrinsic aging of the skin, however, can be controlled to a large extent. Influencing factors include the environment (weather conditions and sunshine), lifestyle (such as smoking and alcohol consumption) and medication. These factors can cause the skin to age prematurely.

In order to reduce the risk of extrinsic skin aging, experts recommend paying attention to daily UV protection – either with a suitable day care product (e.g. Eucerin HYALURON-FILLER Day Care with SPF 30) or with a sun protection product. You should also avoid excessive sunlight and refrain from smoking.

Protection against UVA and UVB radiation

More than 90% of the symptoms of skin ageing are caused by UV radiation* Both UVA and UVB rays can cause sun damage.

UVA rays penetrate deep into the subcutaneous tissue (subcutaneous tissue). They lead to the formation of free radicals and can thus trigger long-term sun damage such as skin aging and skin cancer. UVB rays penetrate less deeply – they lead to acute sunburn and, via direct DNA damage, to long-term skin damage.

We recommend sun protection – UVA and UVB rays can damage your skin.


Although the radiant energy of UVA rays is lower than that of UVB rays, we are exposed to them 30 to 50 times more. They are present throughout the daylight period and with more or less constant intensity throughout the year. Because they can even penetrate through the clouds and through glass panes, you should use care products with a sunscreen even on cloudy days. Long-term sun damage can be prevented in this way.* Source: Ramos-e-Silva et al., Anti-aging cosmetics: Facts and controversies. Clin Dermatol. 2013 Nov/Dec; 31(6): 750-8.

A UV camera can make damage to the skin caused by too much sun visible that is not yet visible to the naked eye.

Preventing sun damage to the skin

The importance of sun protection has been known for a long time and is confirmed by many studies. There is a high level of awareness of the dangers of unprotected skin when exposed to excessive solar radiation. This is shown by the fact that sun protection products are on almost every holiday packing list. Using it on particularly sunny days protects the skin safely from sunburn and long-term UV-induced damage. But what about the areas that are constantly exposed to UV radiation – face, hands and décolleté? It is only gradually becoming generally accepted that the early and regular use of a day cream with sun protection factor or a sunscreen can prevent UV-induced skin aging.

Often we only realize the connection between sun exposure and UV-related skin aging when the first signs of aging become visible.

For example, only when the first wrinkles and small pigment spots appear. To effectively protect yourself from premature skin aging, you should use daily sunscreen all year round.

The Eucerin HYALURON-FILLER day care with SPF 30 offers both wrinkle-filling anti-age care and a high sun protection factor against the negative effects of the sun on the skin.

Sun protection is highly recommended all year round.

Anti-age care with sun protection or sun protection with anti-age effect?

Should one rather use an anti-age care with integrated sun protection or better a sun cream with anti-age effect? This depends on various factors.

Our rule of thumb:

> On sunny summer or winter holidays, sun protection should be the main focus even on cloudy days. For example, use the Face Sun Fluid LSF 50 photoaging control.

> For everyday life in the office or at home without long stays in the sun, the classic anti-age care is recommended – for example the HYALURON-FILLER day care with SPF 30

In principle, anti-ageing and sun products can also be combined well with each other – the product that is applied first is more effective.
