Just when we think there are no more novelties and "revolutionary" ingredients, Korean cosmetics continue to push boundaries and bring us something completely new, distinctive, and a bit quirky. If you follow global trends and major influencers, you've probably already 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 is behind almost all key biological processes — from regulating circadian rhythm to repairing DNA itself. Its levels decline with age, and poor lifestyle and the modern pace of life further reduce it. This is why we see 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 the skin's resistance to stress and damage
- increases skin moisture levels
- stimulates collagen production
- reduces sagging and improves elasticity
- protects the skin from external stressors and pollution
- reduces the degradation of elastin and collagen
In other words, NAD+ slows down skin aging at the cellular level and helps preserve the integrity of genetic material, preventing premature signs of aging.
The result? Skin with improved tone and elasticity, enhanced texture, and a healthier appearance — revitalized 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, the Antioxidant Network, brings 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 NAD+ coenzyme, a complex of 14 peptides, and collagen to visibly alleviate premature signs of aging and reveal a healthy skin glow.
The attractive texture with microcapsules that preserve active ingredients helps reduce the degradation of elastin and collagen, visibly improves compromised skin texture, and reduces 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 will gain momentum and new applications in skincare, as well as for the entire body.
It can be powerful support for proven anti-aging ingredients like retinol and bakuchiol, but also a gentler 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.
