NAD+ and NMN: The Cellular Energy Revolution in Skincare
Skin ageing has many drivers — but one of the most fundamental, and least addressed by conventional aesthetics, is the decline of cellular energy. NAD+ and NMN are changing that.
The Energy Problem at the Root of Skin Ageing
Every cell in the human body runs on energy. That energy is produced primarily through a molecule called NAD+ — Nicotinamide Adenine Dinucleotide — which sits at the centre of cellular metabolism, DNA repair, and gene expression regulation.
From the age of 30, NAD+ levels in human tissue begin to decline — falling by approximately 50% by middle age and continuing to drop thereafter. This decline has profound consequences for skin. Without sufficient NAD+, cells cannot efficiently repair DNA damage, cannot maintain optimal metabolic function, and cannot sustain the rate of collagen production and cellular renewal needed to keep skin looking healthy and youthful.
This is not a peripheral mechanism — it is one of the most fundamental drivers of biological ageing, and it operates entirely beneath the surface of what conventional skincare ingredients address.
What NAD+ Does in the Skin
NAD+ functions as a coenzyme — a molecule that enables and accelerates specific biological reactions. In the context of skin ageing, its most important roles are:
DNA Repair Activation — NAD+ is an essential substrate for PARP enzymes (Poly ADP-Ribose Polymerases), which are the primary machinery of cellular DNA repair. When NAD+ levels are high, DNA damage caused by UV exposure, oxidative stress, and normal metabolic activity is efficiently repaired. When NAD+ declines, this repair capacity degrades — accelerating the accumulation of cellular damage that manifests as visible skin ageing.
Sirtuin Activation — Sirtuins are a family of proteins often called "longevity genes" that regulate cellular stress responses, inflammation, and metabolic efficiency. Sirtuins require NAD+ to function. By restoring NAD+ levels, NAD+-based treatments effectively reactivate sirtuin pathways — reducing inflammation, improving mitochondrial function, and supporting the cellular mechanisms associated with healthier, more resilient skin.
Mitochondrial Function — Mitochondria are the energy-producing organelles within each cell. Their efficiency declines with age, contributing to reduced cellular output across all skin functions — from collagen synthesis to barrier maintenance. NAD+ is central to mitochondrial energy production (the electron transport chain), and restoring its availability directly improves cellular energy output.
NMN: The NAD+ Precursor
NMN — Nicotinamide Mononucleotide — is a direct biosynthetic precursor to NAD+. The body converts NMN into NAD+ through a well-established enzymatic pathway, making NMN supplementation one of the most efficient routes to restoring cellular NAD+ levels.
In aesthetic formulations, NMN is often combined with NAD+ directly — providing both immediate availability of the coenzyme and a sustained biosynthetic pathway for maintaining elevated NAD+ levels over time. This dual-delivery approach produces more consistent and sustained biological effects than either molecule alone.
NAD+ in Aesthetic Practice
When delivered via mesotherapy or micro-needling, NAD+ and NMN work at the cellular level to address the energy decline that conventional skin boosters do not target. Their effects are most pronounced when combined with exosomes and PDRN in a multi-pathway protocol:
The exosomes provide the cellular signals that direct cells toward renewal and repair. PDRN provides the nucleotide building blocks and vascular support. NAD+/NMN provides the cellular energy that powers the entire process — ensuring that cells have the metabolic capacity to act on the signals they receive and execute the repair functions they are being directed to perform.
This three-component approach — signal, structure, energy — represents the most comprehensive biological framework currently available for cellular-level skin rejuvenation in aesthetic medicine.
Clinical Indications
NAD+/NMN-based skin boosters are particularly well-suited for clients presenting with:
Visibly fatigued, dull, or lifeless skin
Fine lines and loss of elasticity associated with intrinsic ageing
Skin that has responded poorly to conventional collagen-stimulating treatments
Post-illness or post-stress skin deterioration
Accelerated ageing associated with high UV exposure or lifestyle factors
