One ingredient conversation gaining serious attention in the world of longevity and skin performance right now is NAD+.
Often referred to as the body’s “cellular battery”, NAD+ plays a critical role in how skin cells produce energy, repair damage, and maintain healthy function over time. But what exactly is it, and why is it becoming such an important focus in skincare?
Here’s what the science says.
What Is NAD+?
NAD+ stands for nicotinamide adenine dinucleotide, a coenzyme naturally found in every living cell.
Its primary role is to help cells produce energy. Every time skin cells repair damage, regenerate, defend against environmental stress, or carry out normal cellular functions, NAD+ is involved somewhere in the process.
In simple terms, NAD+ helps keep skin cells functioning efficiently.
It also plays an important role in:
-
DNA repair
-
Cellular renewal
-
Oxidative stress defence
-
Inflammation regulation
-
Mitochondrial function (the energy centres of cells)
Without adequate NAD+, cells simply don’t function as effectively.
Why NAD+ Matters in Skin Ageing
Like many naturally occurring molecules in the body, NAD+ levels decline with age.
Research suggests this decline can impact how efficiently cells produce energy and repair themselves over time. In skin, that can contribute to visible changes associated with ageing and environmental stress, including:
-
Dullness
-
Reduced elasticity
-
Fine lines
-
Slower recovery
-
Increased sensitivity
-
Loss of resilience
Modern lifestyles can also accelerate this process. UV exposure, pollution, stress, poor sleep, and inflammation all place additional demands on the skin’s repair systems.
As those systems become less efficient, skin can begin to look and feel more fatigued.
The Link Between NAD+ and Cellular Energy
To understand why NAD+ is so important in skincare, it helps to think about skin like a high-functioning system constantly working behind the scenes.
Skin cells require energy to:
-
Produce collagen
-
Repair environmental damage
-
Maintain a healthy barrier
-
Support hydration levels
-
Renew and regenerate
NAD+ is essential to this energy production process because it helps cells generate ATP (adenosine triphosphate), often described as the body's cellular energy currency.
ATP provides the fuel that powers many of the skin's most important functions, including collagen production, barrier maintenance, cellular repair and renewal.
When NAD+ levels are supported, skin cells are better equipped to produce the energy they need to perform these functions efficiently.
That's why NAD+ has become closely associated with longevity science and healthy ageing research.
What Does NAD+ Enzyme Activation Do for Skin?
Here’s where skincare science gets interesting.
NAD+ itself is highly unstable and cannot easily penetrate skin cells in its raw form. That means simply adding NAD+ directly into a formula isn’t the most effective approach.
Instead, modern skincare focuses on supporting the skin's ability to naturally produce its own NAD+.
One of the key pathways involved is an enzyme called NAMPT, which plays an important role in NAD+ biosynthesis - the process cells use to generate NAD+ internally.
This is where our 2% NAD+ Enzyme Activator in our latest Protein Fix comes in. Rather than supplying NAD+ directly, it is designed to support the skin's natural NAD+ production pathways, helping skin cells generate and maintain the NAD+ they need to function efficiently.
By helping support healthy NAD+ levels, our Protein Fix Skin Longevity Booster Drops 10% may help support the cellular energy needed for repair, renewal and overall skin performance.
By helping activate these pathways, skincare can support:
-
Cellular energy production
-
Skin recovery processes
-
Long-term skin resilience
-
More efficient repair mechanisms
This is why many next-generation formulas now focus on NAD+ Enzyme Activation rather than topical NAD+ alone.
Why We’re Interested in NAD+ at Nip+Fab
We’re always interested in skincare that supports skin proactively, not reactively. As skincare continues to evolve, the conversation is shifting away from quick fixes and towards supporting how skin functions over time, helping maintain healthier-looking, more resilient skin for longer.
NAD+ Enzyme Activation represents part of that shift.
By supporting the skin’s natural NAD+ production pathways, NAD+ Enzyme Activation helps optimise cellular energy production, supporting the processes involved in repair, recovery and overall skin function. Combined with advanced ingredients like Exosomes and PDRN, it helps support multiple aspects of skin performance, from cellular communication and regeneration to resilience and recovery.
Rather than focusing solely on surface-level results, this approach is centred around supporting the biological processes that healthy-looking skin depends on.
Because healthy-looking skin isn’t just about what’s happening on the surface.
It starts at a cellular level.
