The role of antioxidants in skin aging

The skin is our largest organ and is exposed daily to countless environmental influences that can cause oxidative stress. Every cell reacts to: UV radiation, pollution, stress, and unhealthy diet – all these factors release free radicals that attack your skin cells and can accelerate the natural aging process. This is where antioxidants come into play: They are considered important allies in the fight against skin aging and are therefore intensively researched and used in both dermatology and anti-aging cosmetics.

Antioxidants have gained enormous importance in recent years. Not without reason – through the right  Dietary supplements they may hold the key to a longer youthful-looking complexion. More and more scientific studies are investigating the connections between oxidative stress, skin aging, and the influence of antioxidant substances. But what exactly is behind the term "antioxidants" and why are they so important for your skin?

What are antioxidants and why are they important for the skin?

Antioxidants are substances that can neutralize free radicals before they cause damage in your body and skin. Free radicals are unstable molecules with unpaired electrons that are constantly searching for a partner. In this search, they can attack and damage cell membranes, proteins, and even DNA. This process is called  oxidative stress referred to.

Oxidative stress in your skin can lead to various problems:

• Breakdown of collagen and elastin, leading to wrinkles and sagging skin
  

• Inflammatory processes that can promote skin diseases
  

• Pigmentation spots caused by damage to melanocytes
  

• Slowed cell renewal and impaired skin barrier
  

• "Accelerated aging processes at the cellular level"
  

An  "Study by the University of Düsseldorf" "has shown that up to 80% of visible skin aging is not due to chronological age but to environmental influences such as UV radiation, which cause oxidative stress. This form of aging is also referred to as extrinsic or photoinduced skin aging."

"Antioxidants form a diverse group of substances that can act against free radicals in different ways. They either donate electrons to free radicals and thereby neutralize them, or they interrupt the chain reaction of radical formation. Some important groups of antioxidants are:"

• "Vitamins (such as C and E)"
  

• "Polyphenols (e.g., from green tea, grape seeds)"
  

• "Carotenoids (such as beta-carotene, lycopene)"
  

• "Flavonoids (such as quercetin)"
  

• "Enzymes (such as superoxide dismutase, glutathione peroxidase)"
  

"Although your body produces some antioxidants itself, with increasing age and under increased stress from environmental factors, this natural defense system can be overwhelmed. Therefore, additional intake through diet or high-quality"  Nutraceuticals "especially important to protect your skin from premature aging."

"How do antioxidants work against skin aging?"

"Antioxidants exert their"  "anti-aging effect" "on various levels and intervene in multiple biological processes that are crucial for skin health and a youthful appearance."

"Neutralization of free radicals"

"The primary mechanism of action of antioxidants is the neutralization of free radicals. By donating an electron to these unstable molecules, antioxidants prevent the harmful chain reaction that would otherwise lead to cell damage. For example, vitamin C as a strong antioxidant can capture free radicals before they can attack the skin's cell structures."

Anti-inflammatory effect

"Chronic inflammatory processes in the skin, also known as " "Inflammaging"" are considered an important factor in skin aging. Many antioxidants such as"  Polyphenols from green tea or  Quercetin could have anti-inflammatory effects by reducing the production of inflammatory mediators and thus breaking the vicious cycle of inflammation and oxidative stress.

Support of collagen production

Collagen is the most abundant protein in your skin and provides firmness and elasticity. With increasing age and under the influence of UV radiation, collagen production decreases while collagen-degrading enzymes (matrix metalloproteinases, MMPs) are increasingly activated. Antioxidants like vitamin C not only play a direct role in collagen synthesis but could also inhibit the excessive activation of MMPs.

A study from the University of Michigan has shown that regular intake of certain antioxidants could increase collagen production by up to 40% while significantly reducing degradation by UV-induced MMPs.

DNA protection and cell regeneration

Free radicals can damage the DNA in skin cells, leading to malfunctions and accelerated aging. Antioxidants like  Astaxanthin, which is said to have 500 times stronger antioxidant effects than vitamin E, could form an effective protective shield for your cellular DNA.

Improvement of skin appearance through regular antioxidant supply

With regular use and intake, antioxidants could cause the following visible improvements:

• Reduced wrinkle depth, especially in fine lines
  

• More even complexion and reduction of pigmentation spots
  

• Increased skin firmness and elasticity
  

• Improved skin barrier function and higher moisture content
  

• Faster regeneration of skin damage
  

While topical applications of antioxidants can act directly on the upper layers of the skin, oral intake of antioxidants in the form of supplements or antioxidant-rich foods allows for a systemic approach. High-quality supplements could provide antioxidants in a bioavailable form and thus promote healthier skin from within.

The best antioxidants for healthy, youthful skin

Vitamin C as a free radical scavenger (ascorbic acid)

Vitamin C is a true all-rounder for your skin. As a water-soluble vitamin, it plays a crucial role in collagen synthesis and can directly neutralize free radicals. In addition, Vitamin C could regulate pigmentation and thus contribute to a more even skin tone.

A clinical study by the Oregon State University Linus Pauling Institute has shown that a combination of orally taken and topically applied vitamin C could significantly reduce wrinkle formation and improve skin elasticity. The benefits of vitamin C for the skin could include:

• Stimulation of collagen synthesis
  

• Protection against UV-induced skin damage
  

• Lightening of hyperpigmentation
  

• Improvement of skin moisture and barrier
  

Nutrador® products with high-dose, especially bioavailable vitamin C could offer your skin these benefits in concentrated form. The special formulations could maximize the absorption and effectiveness of the vitamin.

Vitamin E (Tocopherol)

Vitamin E is a fat-soluble antioxidant that can particularly effectively protect lipids (fats) in cell membranes from oxidation. It often works synergistically with vitamin C and could thus protect the body from free radicals.

Research findings suggest that vitamin E could be particularly effective in:

• to increase skin moisture
  

• to strengthen the skin barrier
  

• to reduce UV-induced oxidative stress
  

• to alleviate inflammatory processes in the skin
  
  

In combination with other antioxidants, vitamin E from  Nutrador® Opti Immun® make an important contribution to maintaining healthy, youthful-looking skin.

Coenzyme Q10

Coenzyme Q10 (CoQ10) is a naturally occurring substance in the body that plays a central role in cellular energy production. With increasing age, the natural CoQ10 level decreases, which can lead to reduced cell energy and increased susceptibility to oxidative stress.

Studies from the University of Hamburg have shown that both topical application and oral intake of CoQ10 could reduce the signs of skin aging:

• Reducing fine lines, especially around the eyes
  

• Protection against UV-induced skin damage
  

• Improving cellular energy production in aging skin cells
  

• Supporting the skin's own antioxidant networks
  
  

The high-quality CoQ10 form in  Nutrador® Coenzyme Q10 could be particularly well absorbed by the body and thus effectively contribute to skin health.

Polyphenols from green tea (EGCG)

Green tea contains potent polyphenols, especially epigallocatechin gallate (EGCG), which are among the strongest known plant antioxidants. Their diverse effects on the skin have been documented in numerous studies.

EGCG and other catechins from green tea could:

• Regulating inflammatory processes in the skin
  

• Stimulating collagen production and inhibiting its breakdown
  

• Promoting cell regeneration
  

• Protecting against UV-induced DNA damage
  
  

Nutrador® formulas with concentrated olive leaf- or green tea extracts could deliver these benefits in a highly bioavailable form.
