sloweddown skin aging process: what triggers it?
With the onset of 25, the human skin begins its aging process. This is marked by the appearance of wrinkles, initially subtle and shallow, later becoming deeper and more prominent. This field of fighting or preventing these signs of aging is a bustling market: there's an array of creams, moisturizers, and masks, along with injections and surgeries commended for skin rejuvenation. Most people yearn for the elegance of aging, but not its visible manifestations.
This natural process isn't a peculiarity; it starts around 25. One reason behind this is the sluggishness of skin cells, as per Prof. Christiane Bayerl, director of the Dermatology and Allergology Clinic at Helios Dr. Horst Schmidt Clinics in Wiesbaden.
This decrease in active skin cells results in a reduction of collagen and elastic fibers in the skin's dermis layer. This causes the skin to lose moisture and elasticity, leading to the formation of wrinkles.
Genetics and lifestyle influence aging
The rate and depth at which wrinkles form varies based on a cocktail of factors. Genetics play a significant role, affirming Julian Nuchel, group leader at the Center for Biochemistry, University of Cologne. Despite an appealing lifestyle, some 80-year-olds maintain youthful skin, while others display deep wrinkles. Analyzing older family members can provide insights into one's own future look. However, lifestyle also influences the early onset and depth of facial wrinkles. This is where we have an impact.
Sun protection is a potent preventive measure, advocates dermatologist Christiane Bayerl. The sun's UV rays stress the skin, causing premature wrinkling and age spots. The radiation damages our DNA, accelerating skin aging and potentially leading to skin cancer in the worst-case scenario.
To shield ourselves, one can opt for the shade or stay indoors during peak sun hours. Additionally, sunscreen, when outside, and clothing should provide ample protection. "UV-A radiation protection is essential in sunscreen during sunny months," emphasizes Julian Nuchel. This radiation greatly contributes to skin aging. He also highlights the importance of year-round sun protection: "Even in winter, the sun emits radiation."
Smoking harms the skin
Another major lurking hazard for the skin is smoking. "It damages blood vessels, giving skin a paler appearance," shares Christiane Bayerl. Studies suggest that the longer and more one smokes, the more aged the skin appears, especially for women.
Heavy environmental pollution also negatively impacts skin, as per Bayerl. Nitrogen oxides, particularly emitted by diesel vehicles, cause age spots. "Research indicates that skin spots make individuals appear 10 years older," she adds.
Aging skin weakens protective abilities
However, skin aging isn't just about aesthetics. As our body's largest organ, the skin performs crucial life-sustaining functions. "It safeguards us against pathogens and retains water," explains Julian Nuchel.
As the skin's strength wanes, inflammation becomes more common, and harmful pathogens can penetrate the body more easily, he warns. "It's essential to preserve the skin's health for as long as possible. The earlier one starts, the better," concludes Nuchel.
Nutrition and exercise care for the skin
Alongside UV protection, a healthy lifestyle is vital - including a balanced diet and exercise. Fruits and vegetables should make up a significant part of one's diet, shares Christiane Bayerl. These food items contain antioxidants that can neutralize free radicals, which can hasten skin aging.
"However, collagen is equally critical," adds the dermatologist. Collagen proteins can be found in meat, fish, eggs, and dairy products. Vegans can rely on alternative sources to boost their collagen production, such as legumes, nuts, and avocados.
Vitamin A and C are also beneficial for the skin, declares Julian Nuchel. Consuming vitamins in foods or using them in creams slows down skin aging. However, the effectiveness is contingent on the concentration in the cream, he cautions. And it's said: "Creams are only effective against fine lines," maintains Christiane Bayerl. That is, rather superficial wrinkles.
Personal care is key
In conclusion, both experts strongly suggest creating a tailored skin care routine. "Customization is key to determining which care works best for an individual," advises Julian Nuchel. A person's skin type, season, and life stage should all inform their skincare choices.
"Prescription anti-aging creams are beneficial, especially for women undergoing menopause or hormonal changes," suggests Christiane Bayerl. Dry skin can also expedite aging, she adds. "It's crucial to cater to the specific needs of dry skin," she advises. This means prioritizing moisture when required.
The role of genetics in skin aging is significant, as mentioned by Julian Nuchel from the Center for Biochemistry at the University of Cologne. Despite similar lifestyles, some individuals may inherit genes that delay the formation and depth of wrinkles, while others may not be so fortunate.
Another factor that can influence the appearance of wrinkles is smoking, according to dermatologist Christiane Bayerl. Smoking not only causes a paler appearance but also accelerates skin aging, especially for women.
