Nicotinamide Adenine Dinucleotide (NAD+) is a vital coenzyme present in all living cells. It is essential for mitochondrial energy production and DNA repair. Unfortunately, NAD+ levels decline by half by the time we reach age 50.
NAD+ precursors like NMN and NR help replenish cellular NAD+ pools. This activates sirtuins—often called the "longevity genes"—which protect cellular health and delay biological aging.

Certain foods contain trace amounts of NMN (like broccoli and avocados), but dietary supplements or topical formulas are necessary for meaningful cellular elevation.
Your skin follows a natural 24-hour rhythm that changes how it protects itself during the day and repairs damage at night. Learn what science says about timing your skincare products to improve hydration, skin barrier function, and healthy aging.
Stress doesn’t just affect your mood — chronically elevated cortisol can break down collagen and trigger visible facial changes. Here’s the actual mechanism behind “cortisol face.
Thin, fragile skin becomes more common with age as collagen production slows and the skin barrier weakens. Discover how niacinamide may improve skin resilience, hydration, and barrier function, plus what current scientific research says about its effectiveness.
