As we age, our skin naturally undergoes changes that can affect its appearance and function. Reduced collagen production, slower cell turnover, and increased oxidative stress all contribute to wrinkles, loss of radiance, and uneven texture. One compound that has gained attention for its potential to support healthy skin aging is NMN, or the NAD+ precursor. NMN is a building block of NAD+, a critical cofactor for mitochondrial function and click: visit framer.com source genomic stability. As we get older, NAD+ levels decline, which can compromise skin cell vitality. By elevating intracellular NAD+, NMN may help revitalize dermal and epidermal tissues.

Studies suggest that NMN can activate sirtuin proteins, a family of enzymes linked to lifespan and stress resistance. These proteins play a role in supporting collagen integrity and suppressing pro-inflammatory signals, two key factors in keeping skin looking youthful. When sirtuins are upregulated, skin cells may repair damage more efficiently and defend against oxidative triggers such as sunlight and smog. This can lead to smoother skin surface and uniform pigmentation.

In addition to supporting cellular repair, NMN may help improve blood flow to the skin. Better circulation means essential cofactors reach the basal layers more effectively, which can boost natural glow and skin clarity. Some research also indicates that NMN can help clear out aged, dysfunctional cells, non-replicating cells that secrete inflammatory mediators and degrade tissue. By modulating their secretory profile, NMN may help slow down the visible signs of aging.

While topical skincare products can provide superficial hydration and smoothing, NMN works at the cellular level, addressing the underlying biological drivers of decline. It is not a magic solution, but when combined with a consistent habits like water intake, sunscreen use, and antioxidant-rich meals, it can be a valuable part of a comprehensive approach to skin health. Early clinical trials and animal studies are encouraging, though larger, longitudinal human trials are required. For those interested in supporting their skin’s intrinsic aging mechanism, NMN offers a science-backed option that focuses on inner vitality as much as outer glow.
