Just when we think that novelties and "revolutionary" ingredients have come to an end, Korean cosmetics continue to push boundaries and bring us something completely new, distinctive, and a bit unconventional. If you follow global trends and major influencers, you've surely come across the name NAD+ — an ingredient that doesn't stop, but significantly slows down aging, and has now found its application in skincare.
This silent "worker" is present in every living cell and underpins almost all key biological processes — from regulating circadian rhythms to repairing DNA itself. With age, its levels decline, and a poor lifestyle and modern pace of life further reduce it. This has led to a huge increase in NAD+ supplements and even intravenous infusions that promise faster recovery from stress, detoxification, or support for mental functions. But what happens when we apply it to the skin?
What is NAD+ and how does it work on the skin?
NAD+ (nicotinamide adenine dinucleotide) is a revitalizing coenzyme that stimulates cellular energy production and repairs damaged tissue, thereby reducing visible signs of aging and wrinkles.
Specifically, NAD+:
- activates SIRT and PARP enzymes that repair sun-induced DNA damage
- strengthens skin's resistance to stress and damage
- increases skin moisture levels
- stimulates collagen production
- reduces sagging and improves elasticity
- protects skin from external stressors and pollution
- reduces elastin and collagen degradation
In other words, NAD+ slows down skin aging at the cellular level and helps preserve the integrity of genetic material, helping to prevent premature signs of aging.
The result? Skin with better tone and elasticity, improved texture, and a healthier appearance — rejuvenated skin radiating youthful vitality.
Where to find NAD+ in cosmetics?
Numbuzin introduces the advanced No.9 product line, recognizable by its attractive purple color. In addition to the NAD+ ingredient, the line also contains a complex of as many as 50 peptides that work synergistically with the main active ingredient and significantly improve skin quality and appearance.
A special group of ingredients, Antioxidant Network, provides a "network" of antioxidants such as astaxanthin, glutathione, resveratrol, and vitamin E, which protect the skin from environmental stressors and pollution and contribute to a refreshed, even, and radiant complexion.

Another k-beauty brand, Eqqualberry, offers the NAD+ Peptide Boosting Serum — a revitalizing serum based on the coenzyme NAD+, a complex of 14 peptides, and collagen for visibly reducing premature signs of aging and revealing a healthy skin glow.
The attractive texture with microcapsules that preserve active ingredients helps reduce elastin and collagen degradation, visibly improves impaired skin texture, and diminishes the appearance of fine lines and wrinkles.
Why is NAD+ the new anti-aging trend?
This is not just another passing trend. NAD+ is an ingredient that we expect to gain momentum and new applications in skincare, as well as for the entire body.
It can be a powerful support for proven anti-aging ingredients like retinol and bakuchiol, but also a milder alternative if the skin doesn't tolerate them. NAD+ does not increase sun sensitivity and can be used daily.
However, to preserve and maximize its effects, we recommend regular use of products with SPF.
