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 nicotinamide mononucleotide. NMN is a building block of NAD+, click: visit framer.com source a critical cofactor for mitochondrial function and genomic stability. As we get older, the body’s NAD+ reservoir depletes, which can compromise skin cell vitality. By restoring NAD+ pools, NMN may help revitalize dermal and epidermal tissues.

Studies suggest that NMN can enhance the activity of sirtuins, a seven key regulators of aging and metabolic balance. These proteins play a role in preserving dermal firmness and calming chronic irritation, two key factors in keeping skin looking youthful. When sirtuins are supported, skin cells may repair damage more efficiently and withstand damage from toxins and blue light. This can lead to smoother skin surface and uniform pigmentation.

In addition to supporting cellular repair, NMN may help increase capillary perfusion to the epidermis. Better circulation means vital compounds are transported to where they’re needed most, which can enhance overall skin luminosity. Some research also indicates that NMN can help diminish the burden of zombie cells, cells that enter a pro-aging state and disrupt neighboring function. By modulating their secretory profile, NMN may help slow down the visible signs of aging.

While topical skincare products can provide surface-level benefits, NMN works at the intracellular foundation, addressing the root causes of skin aging. It is not a magic solution, but when combined with a healthy lifestyle—including proper hydration, sun protection, and a balanced diet, it can be a powerful adjunct in anti-aging skincare. Early clinical trials and animal studies are encouraging, though robust, multi-year clinical data remains to be established. For those interested in supporting their skin’s natural aging process, NMN offers a science-backed option that focuses on inner vitality as much as outer glow.
