Over exposure to the sun is the main cause of premature aging in skin which is known as photoaging. The sun’s UVA rays are primarily responsible, but high-energy visible (HEVIS) light can also cause the oxidative stress that damages cellular DNA. As a result, skin starts to form wrinkles, sag and develop pigmentation issues before its time. Ensuring skin is properly protected year-round, and using superior sun care products, can help to prevent photoaging.
Photoaging is premature skin aging caused by over exposure to the sun’s rays.
When skin ages prematurely it develops signs of aging faster than one would expect. Research shows that up to 90% of all symptoms of premature skin aging are caused by UV
exposure1.

There are two types of skin aging − intrinsic and extrinsic:
Intrinsic aging
As we age, so does our skin. This type of aging is entirely natural and there’s nothing we can do about it. It is known as intrinsic (or chronological) aging. Intrinsic aging is brought about by internal factors such as our genetics and the hormonal changes that happen at the different stages of life.
Extrinsic aging
Extrinsic aging, on the other hand, is controllable. Extrinsic aging is brought about by external factors such as the environment (weather conditions and sun exposure), lifestyle choices (such as smoking and drinking alcohol) and medication. These factors can cause skin to age prematurely.
A UV camera can reveal sun-induced skin damage before it is visible to the human eye.
Photoaging is caused by overexposure to the sun.
The photons in sun’s UVB rays are absorbed by skin cells and cause direct damage to cellular DNA. UVB is what causes our skin to burn in the sun and the direct DNA damage can also lead to skin diseases including skin cancer.
While this direct DNA damage plays a part in the photoaging of skin, it’s the sun’s UVA rays that are the main cause of premature aging in skin. UVA rays also damage cellular DNA, but they do so indirectly: they trigger the formation of free radicals and it’s these free radicals that damage our DNA in a process known as oxidative stress. Recent research has also shown that high-energy visible ( HEVIS) light rays contribute to the premature aging of skin, though to a much lesser extent than UVA. Read more in How the sun ’ s UVA , UVB and HEVIS light rays affect skin.
UVA rays are less intense than UVB, but they are 30 to 50 times more prevalent and are present with relatively equal intensity during all daylight hours throughout the year so it is important to apply sun protection on a daily basis, and all-year-round, to prevent long-term damage. We also recommend that you look out for suncare products that include protection from HEVIS light.
The best way to protect skin from photoaging is to limit the time spent in the sun, avoid it during its most intense hours, wear protective clothing and apply a superior sun protection
product that offers the level of protection that your skin needs. We also recommend that you use sun protection products that have been specially formulated to suit your skin type
and condition. As the face, hands and décolleté are more exposed to the sun than the rest of the body these areas need specific and consistent year-round protection to help reduce
visible signs of aging.
All face and body sunscreens in the Eucerin sun protection range for adults include Eucerin’s Advanced Spectral Technology which combines broadband and photostable UVA/UVB filters1 for superior UV protection with Licochalcone A , a powerful antioxidant which works to neutralize the free radicals caused by UV and HEVIS light. The Eucerin Kids range of sun protection products for children also works to protect sensitive young skin from premature skin aging.

If photoaging is your primary skin concern try:
In addition to Eucerin’s Advanced Spectral Technology the products contain Glycyrrhetinic Acid which supports skin’s own DNA repair mechanism and Hyaluronic Acid which visibly reduces signs of aging. The tinted products also contain color pigments that help to cover uneven pigmentation and instantly unify the complexion.
If you already have pigmentation concerns such as sun or age spots , the Eucerin Anti-Pigment range is clinically proven to be effective at fading them and preventing their reappearance.
