Retinol, hyaluronic acid, vitamin C… meet the latest ingredient set to join this A-list lineup: NAD⁺. Short for the very clinically complex-sounding nicotinamide adenine dinucleotide (don’t worry, it’s friendlier than it looks), NAD⁺ is suddenly cropping up in beauty conversations, wellness supplements, and dermatology circles alike.
Here’s the twist: it’s not some lab-made novelty. NAD⁺ has been in your body all along, quietly helping to power energy, repair cells, and keep skin functioning at its best. So why is it only now becoming the industry’s newest buzzword? Scientists and skin experts are connecting the dots between NAD⁺ levels and visible signs of ageing, sparking fresh excitement about its potential to support skin repair, resilience, and radiance.
In this article, we’ll demystify NAD⁺ by exploring what it does, how it works in the skin, and whether it’s worth adding to your routine. Think of it as your shortcut to understanding the most talked-about (and surprisingly approachable) breakthrough in beauty right now.
What is NAD+ and why is it showing up in skincare?
Let’s get into the science of NAD+. Short for nicotinamide adenine dinucleotide, this coenzyme is found in every cell of the body. Often described as a “cellular battery,” it fuels essential processes such as energy production, DNA repair, inflammation regulation, and overall cellular health. All of which are critical for maintaining youthful, resilient-looking skin.
While NAD⁺ supplements have been around for years, their use in topical skincare is far newer. Due to challenges in delivering the molecule directly into the skin, many formulas use precursor forms such as NMN (nicotinamide mononucleotide), NR (nicotinamide riboside), or niacinamide. Recent breakthroughs in ingredient stability and delivery systems are making topical NAD⁺ a reality and a trending focus in skin science.
So why the sudden buzz? A surge in longevity research, advanced formulation technology, and rising consumer demand for proactive age-defying solutions are spotlighting NAD⁺. This is timely, as NAD⁺ levels naturally decline with age — a key factor in visible skin ageing.
So, does NAD+ slow the ageing process?
NAD⁺ naturally peaks in early adulthood, then gradually declines over time. By midlife, levels can be significantly lower than in youth. This reduction means cells have less “energy” to repair damage, renew themselves and maintain a strong skin barrier. The result? Skin may appear duller, fine lines become more noticeable, and resilience against daily stressors decreases.
Given that NAD⁺ is essential for fundamental skin functions, from repair to protection, supporting its levels through topical application or supplementation is an appealing approach. It’s not a miracle solution, but it may help the skin perform more like it did when NAD⁺ was naturally higher, making it a valuable consideration for healthy-ageing skincare.
How is NAD+ used in skincare?
While NAD⁺ is far from new to science, recent innovation has made it possible to harness it in topical skincare. Once found mainly in supplements, IV drips, and wellness treatments, it’s now part of the growing beauty–wellness crossover trend. Today, you’ll find NAD⁺ skin booster featured in advanced serums, moisturisers and high-performance treatments.
But can NAD⁺ be absorbed through the skin? The answer lies in how it’s delivered. On its own, NAD+ is not efficiently absorbed because of its large and unstable molecule. To overcome this, some products use precursor molecules, such as NMN or NR, which are smaller and more stable, allowing the skin to convert them into NAD⁺.
Others include NAD+ itself, but in stabilised, encapsulated forms designed to improve penetration into skin cells. This is where expert formulation and advanced delivery systems become essential to ensure topical NAD+ products deliver meaningful results.
Why NAD+ deserves a spot in your routine
From boosting cellular energy to supporting repair and resilience, NAD⁺ plays a vital role in maintaining youthful-looking skin. When harnessed in skincare, it helps defend against visible signs of ageing, making it a powerful addition to your daily routine.
This makes NAD+ a true multi-tasking ingredient, helping target dullness, uneven tone, loss of firmness, fine lines and hyperpigmentation - all while supporting well-ageing skin and longevity pathways for skin that looks and feels its best.
Incorporating NAD+ skincare boosters into your routine
NAD⁺ works best when paired with synergistic actives that support its cellular benefits:
While generally compatible with most ingredients, avoid pairing with harsh, unbalanced formulations that could compromise tolerance.
On an INCI list, look for nicotinamide adenine dinucleotide, or precursor forms such as NMN, NR or niacinamide. NAD⁺ is suitable for most skin types, particularly those concerned with premature ageing, dullness or loss of firmness.
In your CSA routine, an NAD⁺ serum is best applied after cleansing and before moisturiser or SPF in the morning, and before night cream in the evening. If you’re using an NAD+ face cream instead, simply use it as your moisturiser step. As with any advanced active, consistency is key to visible results, and always look for products supported by research rather than relying on any generic claims of NAD+ boosters.

The future of NAD+ in skincare
NAD⁺ is more than just the latest buzzword; it’s a molecule your skin already relies on every day, rooted in real biology. While its use in topical skincare is still an emerging area of research, it reflects a wider shift toward longevity-focused, holistic skin health.
For those over 30 looking to proactively support skin ageing, NAD⁺ can be a smart addition to a well-rounded routine. It works best alongside proven actives like vitamin C, vitamin A and peptides, and is most effective when combined within expertly formulated products - not as a standalone replacement.
