Top Nutritional Secrets to Combat Skin Ageing
Skin Ageing: Nutrition Secrets to Slow It Down
Ageing is inevitable, but as a nutritional therapist and beauty therapist, I understand the desire to maintain our youthful glow for as long as possible. Our skin, being the most exposed organ, shows the most visible signs of ageing. So, how can we keep it radiant and healthy throughout the years?
Understanding Skin Ageing
Ageing comes in two forms: intrinsic and extrinsic. Intrinsic ageing is a natural process influenced by our genes and metabolism. Extrinsic ageing, however, results from external factors such as pollution, UV radiation, nutrition, stress, and smoking. While intrinsic ageing can't be stopped, we can reduce the impact of extrinsic ageing through lifestyle and nutrition.
What Happens to Our Skin as We Age?
Several changes occur in our skin as we age:
Thinner Dermis: The dermis layer thins over time, reducing its vascularity and cellularity, including fibroblasts, glycosaminoglycans, and hyaluronic acid.
Lower Collagen Turnover: Collagen production slows, and existing fibres may become cross-linked, causing wrinkles and sagging.
Loss of Elasticity: The dermis becomes more rigid and less elastic.
Pigmentation Changes: Age spots develop due to the senescence of fibroblasts and melanocytes.
Factors Contributing to Skin Ageing
Oxidative Stress
Oxidative stress arises when the production of free radicals (reactive oxygen species, ROS) outpaces antioxidants. ROS damage the dermal extracellular matrix, accelerating both intrinsic and extrinsic ageing. UV radiation increases ROS production, leading to more collagen breakdown and wrinkles.
Advanced Glycation End Products (AGEs)
AGEs are proteins or lipids that become glycated through sugar exposure, leading to stiff and less elastic tissues. This causes collagen fibres to cross-link, weakening their structure.
Cell Cycle Dysfunction
Ageing disrupts the balance between cell death and regeneration, thinning the skin and allowing damaged cells to accumulate, which can increase cancer risk. Factors contributing to this include DNA damage, telomere shortening, and genetic mutations.
Inflammaging
Chronic, low-grade inflammation, known as 'inflammaging,' is a hallmark of ageing and may contribute to diseases like diabetes, Alzheimer's, cardiovascular disease and skin ageing.
The Impact of Menopause on Skin Ageing
Hormonal changes, especially during menopause, significantly impact skin health. As oestrogen levels decline, skin can become thinner, less elastic, and drier. Oestrogen is crucial for maintaining skin’s structure and moisture. Supporting hormone balance during menopause can help mitigate these effects. Additionally, thyroid hormones affect skin metabolism, with hypothyroidism leading to dry and thinning skin. Managing stress to control cortisol levels is also essential, as high cortisol can accelerate skin ageing.
Nutritional Strategies to Mitigate Skin Ageing
Certain nutrients may help slow skin ageing and reduce common age-related skin issues:
Vitamin C: Essential for collagen stabilisation and combating UV-induced free radicals.
Vitamin E: A strong anti-inflammatory that pairs well with Vitamin C for UV protection.
Vitamin D: Protects against UV-induced damage and supports the skin’s antioxidant defences.
Carotenoids: Beta-carotene, astaxanthin, and lycopene protect against oxidative damage and photoageing.
Antioxidants: Polyphenols, resveratrol, soy isoflavones, and curcumin protect against UV-induced inflammation and oxidative stress.
Coenzyme Q10 (CoQ10): Bolsters the skin’s barrier against oxidant assault and enhances elasticity.
Collagen Peptides: Improve skin elasticity and hydration.
Omega-3 Fatty Acids: Reduce inflammation and DNA damage, increasing sunburn threshold.
Probiotics: Mitigate UV-induced skin damage and support overall skin health.
Top 6 Tips for Looking After Your Skin
Stay Hydrated: Drink plenty of water to keep your skin hydrated and flush out toxins.
Eat a Balanced Diet: Include fruits, vegetables, and healthy fats to nourish your skin from within.
Use Sunscreen Daily: Protect your skin from harmful UV rays to prevent photoageing.
Incorporate Antioxidants: Use skincare products and consume foods rich in antioxidants to combat oxidative stress.
Get Enough Sleep: Adequate sleep is essential for skin regeneration and overall health.
Manage Stress: Practice stress-reducing activities like yoga or meditation to keep cortisol levels in check.
Q&A About Skin Ageing
Q: What causes wrinkles and sagging skin?
A: Wrinkles and sagging are primarily caused by reduced collagen production and the cross-linking of collagen fibres, which leads to loss of skin structure and elasticity.
Q: How does UV radiation affect skin ageing?
A: UV radiation increases the production of reactive oxygen species (ROS), which degrade collagen and accelerate skin ageing, leading to wrinkles and sunspots.
Q: Can diet really impact skin ageing?
A: Absolutely! A diet rich in antioxidants, vitamins, and healthy fats can significantly reduce oxidative stress and inflammation, promoting healthier, younger-looking skin.
Q: How do hormones influence skin ageing?
A: Hormones like oestrogen and thyroid hormone play crucial roles in maintaining skin thickness, moisture, and elasticity. Menopause and thyroid issues can accelerate skin ageing.
Q: What are some effective natural antioxidants for skin health?
A: Resveratrol, found in red grapes and red wine, soy isoflavones, curcumin from turmeric, and cocoa flavanols are all powerful natural antioxidants that protect against UV damage and oxidative stress.
Q: Is it worth taking collagen supplements for skin health?
A: Yes, studies show that collagen supplements can improve skin elasticity and hydration, leading to a more youthful appearance.

Key Points
Skin is particularly vulnerable to ageing due to constant environmental exposure.
Intrinsic ageing is influenced by genetics and metabolism, while extrinsic ageing is driven by environmental factors.
Oxidative stress, DNA damage, and chronic inflammation are key mechanisms of skin ageing.
Nutrients like vitamins A, E, and D, carotenoids, botanical antioxidants, CoQ10, collagen peptides, omega-3 fatty acids, and probiotics can help mitigate skin ageing.
By understanding the factors contributing to skin ageing and incorporating the right nutrients into your diet and skincare routine, you can maintain youthful, radiant skin for years to come. Let’s embrace ageing gracefully and keep our skin healthy and glowing.
Important Notice: Before taking any supplements, it is crucial to consult with your doctor or a qualified healthcare professional. Supplements can interact with medications, underlying health conditions, or specific nutritional needs. Always seek professional advice to ensure that any supplement is safe and appropriate for your individual health situation.
