NAD+ and its potent anti-aging and regenerative skin effect
Share
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in all living cells and plays a critical role in energy metabolism and cellular repair. In skincare and anti-aging science, NAD is gaining attention because of its ability to help repair, protect, and revitalize aging skin on a cellular level.
🔬 Anti-Aging Effects of NAD in Skin:
1. Supports Cellular Energy (ATP Production):
NAD is essential for mitochondrial function.
Aging skin has less energy (ATP), which slows repair and turnover.
Boosting NAD levels helps energize skin cells, improving their ability to renew and function optimally.
2. Activates Sirtuins (Longevity Genes):
Sirtuins are proteins that regulate aging and inflammation.

NAD is required to activate sirtuins, which:
Enhance DNA repair
Promote skin firmness and elasticity
Protect against oxidative stress
3. Enhances DNA Repair:
As we age, DNA damage accumulates in skin cells from UV, pollution, and stress.
NAD is a cofactor for enzymes like PARPs (poly ADP-ribose polymerases), which help repair DNA damage.
This slows down signs of photoaging like wrinkles and pigmentation.
4. Reduces Inflammation & Oxidative Stress:
NAD plays a role in neutralizing free radicals and reducing chronic skin inflammation, both of which accelerate aging.
Helps maintain a balanced skin barrier and reduce visible redness or roughness.
5. Stimulates Skin Renewal & Barrier Function:
-
By energizing cells and supporting repair, NAD can:
Increase collagen and elastin synthesis
Improve skin hydration and smoothness
Restore a more youthful glow and resilience
