One of the most exciting developments in anti-aging medicine in 2026 is the improved understanding of the effects of the NAD+ (Nicotinamide Adenine Dinucleotide) molecule on skin health. This coenzyme, which sits at the center of cellular energy production, declines dramatically with age — and this decline produces directly observable consequences in the skin.
What Is NAD+ and Why Does It Decline?
NAD+ is a fundamental coenzyme found in every cell in the body and involved in more than 500 enzymatic reactions. Vital functions such as energy production in the mitochondria, DNA repair, and cellular signal transduction cannot take place without NAD+.
Research shows that by age 50, NAD+ levels drop to approximately half of what they were in one's twenties. This decline directly affects the capacity of skin cells to produce energy, repair themselves, and regenerate.
The Effects of NAD+ Decline on the Skin
Mitochondrial Dysfunction
When NAD+ levels drop, mitochondrial energy production slows down. Fibroblast cells become unable to generate sufficient energy, and collagen and elastin synthesis decreases. The result: skin thinning, wrinkles, and loss of elasticity.
Reduced DNA Repair Capacity
NAD+ is required for PARP enzymes to function. PARP enzymes repair DNA breaks caused by UV damage and oxidative stress. When NAD+ is deficient, this repair mechanism fails and cellular aging accelerates.
Decreased Sirtuin Activity
Sirtuin proteins, also known as "longevity genes," are enzymes that regulate cellular aging. The activity of these enzymes is entirely NAD+-dependent. When sirtuin activity drops, inflammation increases, cellular stress responses weaken, and aging accelerates.
NAD+-Based Skin Treatments in 2026
NMN (Nicotinamide Mononucleotide) Supplementation
NMN is a precursor molecule that is converted directly into NAD+ in the body. Clinical studies have shown that NMN taken as an oral supplement increases skin elasticity and strengthens the moisture barrier.
Topical NAD+ Precursors
In 2026, next-generation topical NAD+ precursors that go beyond niacinamide formulations have the capacity to penetrate into the deeper layers of the skin and increase local NAD+ levels. These products directly support fibroblast activation and collagen synthesis.
IV NAD+ Therapy
Intravenous NAD+ infusions rapidly elevate systemic NAD+ levels. This treatment increases the skin's overall regeneration capacity while also producing positive effects on energy levels and cognitive function.
Combined Protocols
The most effective results from NAD+ treatments emerge when combined with antioxidant support, polyphenol supplementation, and lifestyle interventions. Practices such as intermittent fasting and regular exercise support the body's natural NAD+ production.
The NAD+ Approach at Virtuana Clinic
At Virtuana Clinic, we conduct an individual assessment of NAD+ levels and create personalised treatment protocols for each patient. Our holistic programmes — encompassing topical applications, oral supplements, and IV therapy options where needed — address skin aging at the cellular level.
Cellular energy is the foundation of youth. By optimising NAD+ levels, you can re-energise your skin at the cellular level. Please contact us for pricing and a personalised consultation.
