Does NAD+ Improve Skin Health?

Healthy skin isn’t just about looking younger, it often reflects your overall wellbeing.

When your skin appears clear, hydrated, and vibrant, it can be a sign that your body is functioning well and maintaining balance internally. There are many ways to support healthier-looking skin. In recent years, NAD+ has gained increasing attention in the context of anti-ageing and skin health, as more people focus on longevity and optimising their overall wellness.

NAD+ is closely linked to cellular function, which is why it has become relevant in discussions around skin health. Understanding what NAD+ is, how it supports the body, and how it may influence the skin can help you make more informed decisions about incorporating it into your routine.

Qu'est-ce que le NAD+ ?

NAD+ stands for nicotinamide adenine dinucleotide. It is a naturally occurring coenzyme found in every cell of the body. Unlike many topical anti-ageing ingredients, NAD+ works at a cellular level, supporting essential processes that keep your cells functioning efficiently.

One of its primary roles is in cellular energy production. NAD+ is involved in mitochondrial function, often referred to as the “powerhouse” of the cell, where nutrients from food are converted into usable energy.

In addition to energy production, NAD+ also plays a role in:

How Skin Ageing Occurs

Skin ageing is a natural process influenced by several biological factors, including:

Collagen Production

Collagen is a key structural protein that helps maintain the skin’s firmness and elasticity. From around the mid-20s, collagen production gradually declines, which can lead to fine lines, reduced elasticity, and thinning of the skin over time.

Stress oxydatif

Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body. Free radicals can damage cells and DNA, contributing to inflammation, dullness, and the visible signs of ageing.

Reduced Cell Activity

As we age, cellular processes become less efficient. Skin cells are slower to renew and repair, leading to a build-up of older cells. This can weaken the skin’s structure and affect proteins such as collagen and elastin, which are essential for maintaining firmness and resilience.

The Relationship Between NAD+ and Skin

Because NAD+ is present in every cell, it plays an important role in supporting overall skin health. Its involvement in key cellular processes means it can contribute to how the skin functions and repairs over time.

Cell turnover

Healthy skin relies on continuous cell turnover, the process where old cells are replaced by new ones. This helps maintain a smooth, vibrant appearance.

This process requires significant cellular energy. NAD+ supports the production of ATP (the body’s main energy source), which helps power cell renewal and overall skin function.

Repair processes

NAD+ is also involved in DNA repair by activating enzymes known as PARPs. These enzymes help identify and repair cellular damage.

When repair processes become less efficient, damage can accumulate over time, contributing to visible signs of ageing such as fine lines and wrinkles.

Inflammation regulation

While inflammation is a natural and necessary response, chronic low-level inflammation can negatively affect skin health.

NAD+ plays a role in helping regulate inflammatory pathways, supporting a more balanced immune response and contributing to healthier skin over time.

Does NAD+ Improve Skin Health?

While research is still developing, NAD+ is associated with several potential benefits for skin health, largely due to its role in supporting cellular function.

What Research Suggests

Studies around NAD+ and skin health are still emerging, with some promising outcomes.

A study from 2024 found that women using a supplement containing nicotinamide riboside (a NAD+ precursor) reported improvements in skin smoothness, reduced wrinkles and skin recovery. Another from the same year suggested that improving NAD+ levels may improve collagen and elastin production, leading to improved skin elasticity and firmness.

Most studies so far have been on animals. A study on mice in 2021 had preliminary evidence that NAD+ promoted more organised collagen remodelling, which could result in improved scar appearance and help prevent them.

Ways to Support NAD+ Levels

There are several ways to support NAD+ levels, which may help optimise the cellular processes linked to skin health.

Mode de vie

NAD+ levels can be supported naturally through lifestyle choices https://nadplusathome.com/articles/how-to-naturally-boost-your-nad-levels/  Two of the most important factors are diet and exercise. 

Régime alimentaire

A balanced diet that includes nutrient-dense foods can help support the body’s natural NAD+ production. These include:

These foods provide key nutrients involved in cellular energy and metabolic processes.

Exercise

Physical activity increases the body’s demand for energy, which can help stimulate more efficient energy production at a cellular level. Regular exercise is also associated with improved sleep, reduced stress, and overall metabolic health, all of which may support NAD+ levels indirectly.

Supplementation

Supplementation can be a helpful way to support NAD+ levels as part of a consistent wellness routine.

Oral supplements

Oral NAD+ can provide a convenient and accessible option. Our formulations deliver meaningful doses (often around 250mg), helping to support NAD+ levels and overall cellular function over time. They are particularly useful for maintaining consistency within a daily routine.

Injectable NAD+

Injections de NAD offer a more direct method of delivery and are generally considered the gold standard in terms of bioavailability. By bypassing the digestive system, they allow for more efficient absorption, which may lead to a more noticeable effect for some individuals.

Both approaches can be effective, and the best option often depends on individual preferences, lifestyle, and goals.

Who Is This Most Relevant For?

NAD+ support may be particularly relevant for a range of individuals, including:

People over 35

NAD+ levels naturally begin to decline with age,  typically becoming more noticeable from around the late 30s onwards. This often coincides with the early visible signs of skin ageing, such as reduced elasticity and slower skin renewal.

Wellness and longevity-focused individuals

Those already focused on optimising their health and supporting long-term wellbeing may find NAD+ a useful addition to their routine, particularly as part of a broader approach to cellular health.

People looking to support skin health

If your goal is to maintain healthier-looking skin or support the natural ageing process, optimising NAD+ levels may play a supportive role alongside other lifestyle factors.

Does NAD+ Improve Skin Health? Limitations and Considerations

While the potential benefits of NAD+ are promising, it’s important to recognise that the science is still evolving. More research, particularly in human studies, is needed to provide definitive conclusions about its effects on skin health.

NAD+ supplementation should not be viewed as a standalone solution. Healthy skin is influenced by a range of factors, including diet, sleep, stress management, and regular exercise. Supplementation is most effective when used to support these established lifestyle foundations.

It’s also important to keep in mind that individual responses can vary. Results are not guaranteed, and improvements are typically gradual rather than immediate. The most effective approach is to incorporate NAD+ as part of a consistent, long-term routine that supports overall health and wellbeing.

NAD+ plays a role in several natural processes within the body that are linked to skin health, including energy production, cellular repair, and inflammation regulation. Supporting NAD+ levels may help optimise how these processes function over time.

While supplementation can be a useful tool, it is most effective when combined with a balanced lifestyle that includes good nutrition, quality sleep, and regular exercise.If you’d like to learn more about NAD+ and how it may support your skin and overall wellbeing, or if you have any questions about our products, the NAD+ At Home team is here to help. https://nadplusathome.com/contact-us/
