How to look younger: Skin longevity

Skin longevity is about more than just reducing wrinkles—it's about preserving the skin’s health, strength, and vitality over time. Recent advances in epigenetics reveal that lifestyle and skincare can influence how our genes behave, affecting how the skin ages.  

By targeting these processes, it's now possible to promote long-term skin health and reverse visible signs of ageing. With science-backed formulas, the Eucerin Hyaluron-Filler range supports skin longevity from the inside out and can help make the skin look younger.

Our skin begins to change at around age 25 due to several factors, which can be divided into two main categories. 

Internal ageing is the natural, biological process of skin ageing that happens over time. It's largely influenced by genetics and involves: 

• Slower cell turnover 
• Reduced collagen and elastin production 
• Thinner, drier skin
• Fine lines and gradual loss of firmness 

External influences like environmental and lifestyle factors also cause visible signs of ageing. These include: 

• UV radiation (photoageing) 
• Pollution 
• Smoking 
• Poor diet
• Stress and lack of sleep 

External ageing can accelerate the visible signs of ageing, such as wrinkles, hyperpigmentation, and dullness.

Epigenetics is the study of how external factors can turn genes "on" or "off" without changing your DNA sequence. Thanks to advances in epigenetics, and innovations like Eucerin’s Age Clock Technology, we now know that external factors like UV exposure, pollution, and stress can influence how your skin cells behave, potentially speeding up visible ageing.  

This is where the concept of skin longevity comes in: helping your skin function in a healthier, more youthful way for longer.

Skin longevity refers to the skin’s long-term health, resilience, and youthful appearance as it ages. It is influenced by both internal and external ageing factors, as well as epigenetics.

Promoting skin longevity isn’t just about genetics, it is also influenced by the skincare you use. As science uncovers more about how lifestyle and environmental factors influence how our skin ages, targeted skincare has become a powerful tool to support healthy, younger-looking skin over time. 

The right products can help protect skin from external stressors, boost its natural repair processes, and even influence gene activity linked to ageing.

To tackle the deeper biological processes of skin ageing, we have developed a next-generation skincare innovation: Eucerin Hyaluron-Filler Epigenetic Serum 

Harnessing the power of Epicelline, this serum reduces signs of ageing and keeps the skin looking young. This anti-ageing serum works by: 

• reactivating the genes that keep us looking youthful 
• rejuvenating the skin cells while reversing 

There are several simple lifestyle and skincare changes that can be made to maintain your skin’s youthful appearance.

Sun protection is one of the most effective ways to keep the skin looking young as well as care for ageing skin. Exposure to the sun’s UV rays and HEVIS light is the main contributor to hyperpigmentation and photoageing (sun induced skin damage).

The UV rays of the sun can seriously harm skin by burning it and causing DNA changes at a cellular level, resulting in wrinkles and decreased elasticity. Over time, this can cause skin to age prematurely and make it look older than it is.

Eucerin’s Sun Protection range defends against UVA and UVB rays as well as HEVIS light, to offer complete protection against sun-induced skin conditions.

Moisturising plays a crucial role in how to get younger looking skin. It helps to hydrate ageing skin, making fine lines less visible and your skin smoother. It helps the skin stay firm and elastic, reducing sagging. 

Moisturisers also protect the skin from things like pollution and extreme weather conditions, which can age your skin faster. Regular moisturisation supports skin repair, reducing irritation and keeping the skin looking healthy. 

We recommend Eucerin Hyaluron-Filler SPF 30 for daily moisture and care. Formulated with Hyaluronic Acid, this day cream helps reduce fine lines and even deep wrinkles for a rejuvenated look.

Hyperpigmentation appears as dark patches on the skin and can make someone appear older as an uneven skin tone is often associated with ageing. Dark patches from factors like sun damage and acne scars can also make fine lines and wrinkles more noticeable. 

To reduce the appearance of hyperpigmentation, Thiamidol is clinically-proven to reduce areas of hyperpigmentation and prevent them from reappearing*. Eucerin’s Anti-Pigment range offers a variety of products, from body and face creams to targeted solutions, meaning you can treat your hyperpigmentation from head to toe and make you skin look younger.

* First results are visible after two weeks and improve continuously with regular use.

Similarly to moisturising, drinking enough water also ensures the skin remains plump and elastic and is essential to maintaining the skin’s appearance and health. When our bodies are well hydrated, it can circulate nutrients to your skin cells more effectively, promoting healthy skin function and regeneration. 

This leads to a reduction in the appearance of fine lines and wrinkles, a more even skin tone and an overall skin that looks and feels more radiant. Learn more about signs of dehydrated skin.

Our diets can also impact the appearance of our skin. Consuming foods rich in antioxidants like fruits and vegetables can combat skin damage caused by free radicals, reducing signs of ageing. Vitamin E is a powerful antioxidant for younger-looking skin, and can be found in seeds, nuts and grains and vitamin C is essential for skin health.

Sleep is a major part of how to get younger looking skin as it is when the body repairs itself. During deep sleep, the skin’s blood flow increases allowing for the repair of damage from UV exposure, in turn reducing wrinkles and age spots. Sleep also boosts collagen production, essential for ageing skin elasticity and preventing sagging.  

Lack of sleep can result in dark circles under the eyes in the short term, but over time it can lead to stress which may increase cortisol levels and break down collagen, accelerating ageing.

Along with drinking more water and getting more sleep, doing more exercise can also make the skin look younger as well as benefit overall health. Frequent exercise helps prolong the youthful appearance of your skin. It enhances circulation, supplying your ageing skin cells with more blood and oxygen to maintain their elasticity and vitality.

Looking after your neck and chest area as well as your face is key in how to get younger looking skin. The skin on our neck is thinner than facial skin, so requires care and protection from external factors. Learn more about how to look after your neck and chest area.

Our hands are exposed to the elements every day and are especially prone to drying and ageing.

Finally, our feet do a great job of bearing our weight every day but due to a lack of oil glands, they can easily dry out. Feet are often neglected from skincare routines but can benefit from specialised products to maintain their health, like the UreaRepair Foot Cream. Learn more about caring for skin on the feet.
