UV radiation damages skin in several ways, including direct cell damage, gene mutations, oxidative stress, inflammation, suppression of antitumor immunity, and the creation of an “energy crisis” in skin cells which hinders effective DNA repair and can result in skin cancer.

But replenishing NAD can protect your skin.

Here are the studies:

A Narrative Review of Nicotinamide Adenine Dinucleotide (NAD)+ Intermediates Nicotinamide Riboside and Nicotinamide Mononucleotide for Keratinocyte Carcinoma Risk Reduction

Kahn, Benjamin

Stem Cells

Oral nicotinamide (NAM) supplementation has been shown to decrease the incidence of keratinocyte carcinoma (KC) in high-risk skin cancer patients. NAM is a nicotinamide adenine dinucleotide (NAD+) intermediate and thus directly leads to increased NAD+. This increase in NAD+ is believed to be responsible for NAM’s impact on keratinocyte carcinoma risk. NAD+ has protective cellular effects and is a necessary cofactor for DNA repair, helping to prevent potentially oncogenic mutations. Nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) are NAD+ intermediates like NAM...

The Role of NAD+ in Regenerative Medicine

Conlon, Nichola

Stem Cells

Addressing aging at the cellular level is now critically important. Many surgical procedures rely on the healing and regenerative capacity of the skin which is known to decline with age, leading to disappointing results or negative postsurgery outcomes. Improving health and resilience at the cellular level with NAD+ restoration could be harnessed as a way to ensure consistent results and recovery irrespective of patient age. It should also be noted that the efficacy of many nonsurgical aesthetic procedures such as microneedling and laser technologies ultimately rely on the activation of cellular stress pathways to trigger the clearance of damaged cells and stimulate the production of new collagen. Many of these pathways require adequate NAD+ levels for optimal function, meaning NAD+ restoration before treatment could be a strategy to ensure the underlying cells are in an optimal condition to respond to the treatment.

Nicotinamide for photoprotection and skin cancer chemoprevention: A review of efficacy and safety

Snaidr, Victoria A.

Stem Cells

The future of NAM as a photoprotective agent is promising, with this paper highlighting its positive safety profile and showing evidence supporting its utility in those patients at high risk for the development of non-melanoma skin cancer.

A Phase 3 Randomized Trial of Nicotinamide for Skin-Cancer Chemoprevention

Chen, Andrew

Stem Cells

In this phase 3, double-blind, randomized, controlled trial, we randomly assigned, in a 1:1 ratio, 386 participants who had had at least two nonmelanoma skin cancers in the previous 5 years to receive 500 mg of nicotinamide twice daily or placebo for 12 months. Participants were evaluated by dermatologists at 3-month intervals for 18 months...Oral nicotinamide was safe and effective in reducing the rates of new nonmelanoma skin cancers and actinic keratoses in high-risk patients
