Discover the truth about ageing skin as we debunk common myths and misconceptions. Learn how genetics, lifestyle, and supplementation, specifically NAD+, play a critical role in skin health. 

How's the old saying go — "wrinkles should merely indicate where smiles have been"? Skin, the largest organ of our human body, symbolizes our health and age. Indeed, our skin changes as we accumulate more candles on our birthday cake, a process most often associated with loss of elasticity, wrinkles, and age spots. But how much do we really know about ageing skin? Is it true that certain products can achieve the Ponce de Leon's elusive “fountain of youth”? Well, it's high time we separate myths from facts when it comes to skin ageing. 

1. Debunking the Genetics-only Skin Ageing Myth

Fact or Fallacy: Skin Ageing is Solely Determined by Genetics 

Many folks assume, "My mum has great skin, so I will too!" But hold your horses, because this is partly true. Yes, genetics play a role in how our skin ages—this is known as intrinsic ageing1. Factors beyond our control like genetic makeup and hormonal changes contribute to skin ageing. But let's not forget our dear accomplice, the environment—extrinsic ageing. Frequent sunbathing days, smoking, and poor nutrition contribute significantly to wrinkles and age spots2. So, while mom’s genes may give you a head start, you’re not entirely off the hook! 

 2. Unmasking the Magic Potion Myth

Can Products Completely Reverse Ageing? 

Regrettably, no magical potion can turn back the hands of time — sorry to burst that bubble. No over-the-counter product can completely reverse skin ageing3. Why? Because skin aging is a natural biological process. However, certain products can help slow down the ageing process and rejuvenate the skin. Sunscreens, moisturizers, and retinoids are scientifically proven to reduce signs of ageing4. Remember, consistency is key — these products should be part of your daily skin care regimen. 

3.The Fascinating NAD+ Connection

NAD+ and Skin Ageing: What's the deal? 

Nicotinamide adenine dinucleotide (NAD+), a coenzyme found in all living cells, plays an important role in cellular energy metabolism. Research shows that our NAD+ levels decline as we age, leading to cellular damage and, yes, skin ageing5. 

How does NAD+ fit into this picture, then? Studies suggest that boosting NAD+ levels, either through diet or supplementation, can help slow down the ageing process by repairing damaged DNA and promoting skin cell regeneration6. This compelling research opens a new doorway to approach skin ageing. However, more research is needed to establish the unquestionable benefits and safety of prolonged NAD+ supplementation.  

FAQs 

1. Does ageing skin mean unhealthy skin? 

• Not necessarily! Ageing is a natural process, and changes in the skin are part of that process. It's important to maintain a healthy skincare routine, eat a balanced diet, and protect your skin from harmful sun exposure to keep it healthy. 

1. Can I change the way my skin ages? 

• Absolutely. While genetic factors (intrinsic ageing) are beyond our control, we can influence environmental factors (extrinsic ageing). Protect your skin from the sun, eat healthy foods, hydrate, stop smoking, and maintain a consistent skincare routine. 

1. Are anti-ageing products only for older adults? 

• Not at all. Prevention is key when it comes to skin ageing. Starting a skin care regimen early can help delay signs of ageing. 

Knowledge is skin power! Understanding the realities of skin ageing helps us make informed decisions about skin care. In essence, a combination of genetics, lifestyle, and potentially supplementation with molecules like NAD+ influence skin ageing. It's time we debunked these skin ageing myths and gave more grace to our laugh lines.
