Beyond hyaluronic acid and retinol, a groundbreaking compound is revolutionizing the NAD skincare industry: NAD+. Scientists have discovered that this coenzyme plays a fundamental role in cellular repair and longevity, potentially addressing aging at its molecular source. Unlike traditional anti-aging ingredients that merely mask symptoms, NAD skincare products target the very mechanisms of cellular aging—potentially offering what researchers are cautiously calling a “reset button” for skin cells experiencing age-related decline.
The NAD skincare community has understandably taken notice, with NAD+ and its precursors becoming increasingly incorporated into premium formulations. However, dermatologists caution that while the science behind NAD skin care is compelling, its practical application in topical products is still evolving. We consulted three renowned dermatologists—Dr. Rebecca Zhang, Dr. Michael Levine, and Dr. Sarah Johnson—to separate fact from fiction about this promising NAD skin care ingredient. Here’s what NAD skin care enthusiasts need to know.

Meet the Experts
Dr. Rebecca Zhang, MD, FAAD, is a board-certified dermatologist specializing in cosmetic dermatology and skin aging at Columbia University Medical Center and author of “The Science of Skin Renewal,” who has researched NAD skincare applications extensively.
Dr. Michael Levine, MD, PhD, is a dermatologist and cellular biologist at Mayo Clinic with extensive research experience in metabolic skin disorders and NAD skincare pathways for cellular rejuvenation.
Dr. Sarah Johnson, MD, FAAD, is a clinical dermatologist at Northwestern University Feinberg School of Medicine and Director of the Skin Aging and Rejuvenation Research Center, where she leads clinical trials on NAD skincare formulations.
What Is NAD+?
“NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of our body that’s essential for fundamental biological processes,” explains Dr. Zhang. “It serves as a critical component in cellular metabolism, DNA repair, and energy production. Think of NAD+ as the cellular currency that powers the enzymes responsible for keeping our cells functioning optimally, which is why NAD skincare products are generating so much excitement.”
Dr. Levine elaborates: “NAD+ levels naturally decline as we age—by our 60s, we typically have less than half the NAD+ we had in our 20s. This decline correlates directly with many hallmarks of aging, including reduced cellular energy, compromised DNA repair, and diminished skin barrier function. Effective NAD skincare aims to counteract this decline.”
This age-related NAD+ depletion is exacerbated by environmental stressors like UV radiation and pollution. “When skin is exposed to these stressors, NAD+ reserves are rapidly depleted as cells work to repair damage,” notes Dr. Johnson. “Without sufficient NAD+, skin cells essentially lose their ability to effectively recover from daily damage, accelerating visible signs of aging—which is precisely what advanced NAD skincare formulations address.”
What Are the Benefits of NAD+ for Skin?
The potential benefits of restoring optimal NAD+ levels in skin cells are significant. Research on NAD skincare suggests that NAD+ may help address multiple aspects of skin aging simultaneously, which is why it’s generating such excitement in dermatological circles.
“NAD skincare supports several critical skin functions,” says Dr. Zhang. “First, it enhances cellular energy production, which is essential for skin regeneration and repair. Second, it activates sirtuins—proteins that regulate cellular health and longevity. Third, it strengthens the skin’s defense against oxidative stress and environmental damage.”
Clinical observations suggest that topical NAD skincare formulations may help:
- Improve skin elasticity and firmness
- Enhance skin texture and reduce roughness
- Diminish the appearance of fine lines and wrinkles
- Support skin barrier function and hydration
- Promote more even skin tone
- Accelerate skin recovery after environmental exposure
“What makes NAD skincare particularly interesting is its role in mitochondrial function,” adds Dr. Levine. “Mitochondria are the powerhouses of cells, and their dysfunction is a key factor in skin aging. By supporting mitochondrial health, NAD skincare essentially helps skin cells maintain their youthful energy levels and function.”
However, Dr. Johnson emphasizes an important distinction: “While the science behind NAD+’s role in cellular aging is robust, translating this into effective NAD skincare formulations presents challenges. The NAD+ molecule itself is relatively large and unstable, making direct topical application problematic.”
What Skincare Item(s) Contain NAD+?
Due to the challenges of formulating with pure NAD+, most NAD skincare products use precursors or derivatives that the skin can convert into NAD+. The most common approach in NAD skincare is incorporating niacinamide (vitamin B3), a well-established NAD+ precursor with excellent skin penetration properties.
Dr. Johnson breaks down the current NAD skincare landscape:
Serums and Concentrates: These typically contain high concentrations of NAD+ precursors like niacinamide, nicotinic acid, or newer compounds like nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR). These lightweight NAD skincare formulations are designed for maximum penetration and targeted delivery of active ingredients.
Creams and Moisturizers: NAD skincare moisturizers often combine precursors with complementary ingredients like peptides, antioxidants, and barrier-supporting lipids to create comprehensive anti-aging formulations. These work well for dry or mature skin types seeking NAD skincare benefits.
Eye Products: The delicate eye area, which often shows the first signs of aging, can benefit from NAD skincare precursors that support cellular energy and diminish fine lines. These NAD skincare formulations are typically lighter and specifically tested for the sensitive eye area.
Masks and Intensive Treatments: Higher-concentration NAD skincare treatments deliver periodic boosts to skin’s NAD+ pathway. These products often incorporate delivery technologies to enhance penetration during the treatment period.
Cleansers: While less common, some cleansers now include niacinamide to begin the NAD+ boosting process from the first step of a skincare routine. The brief contact time means benefits are modest but can complement other NAD skincare products.
Sun Protection: Advanced sunscreens now combine UV filters with NAD+ precursors to simultaneously protect skin from damage while supporting its repair mechanisms, making them multifunctional NAD skincare options.
Neck and Décolletage Products: These often-neglected areas can show significant signs of aging and may benefit from specialized NAD skincare formulations designed for the thinner skin of these regions.
“When evaluating NAD skincare products, concentration and formulation matter tremendously,” cautions Dr. Levine. “Look for NAD skincare that discloses the percentage of NAD+ precursors—ideally 2-10% for niacinamide—and that incorporate complementary ingredients that enhance stability and penetration.”
Does NAD+ Skincare Work?
The efficacy of NAD skin care remains an area of active research and some debate within the dermatological community. While the biological importance of NAD+ is well-established, translating this into effective topical NAD skin care formulations presents challenges.
“The preliminary data on topical NAD skin care precursors is promising,” says Dr. Zhang. “Studies show that niacinamide, the most well-researched precursor in NAD skin care, can improve multiple signs of aging when applied topically at appropriate concentrations. However, newer NAD skin care precursors like NMN and NR need more human clinical studies specifically examining their topical effects.”
Dr. Levine adds an important perspective: “The skin is remarkably responsive to NAD skin care pathway stimulation compared to many other tissues. This is partly because skin is constantly exposed to stressors that deplete NAD+, creating a situation where replenishment through targeted NAD skin care can have notable benefits. That said, results will vary based on your baseline skin condition, age, and the specific NAD skincare formulation used.”
Recent advances in delivery technology have improved the potential efficacy of NAD skin care. “Liposomal delivery systems, nanoparticle carriers, and other advanced formulation techniques can significantly enhance the stability and penetration of NAD+ precursors in NAD skincare,” explains Dr. Johnson. “The most effective NAD skincare products leverage these technologies rather than simply including an ingredient on the label.”
For those considering NAD skincare, the experts recommend managing expectations. “You’re likely to see subtle improvements in skin texture and resilience within weeks of using quality NAD skincare, but the more significant benefits to elasticity and wrinkle reduction typically emerge over months of consistent use,” says Dr. Zhang.
Potential Side Effects
While NAD+ precursors in NAD+ skincare generally have excellent safety profiles, they aren’t without potential side effects.
“Niacinamide, the most common NAD skincare precursor, is remarkably well-tolerated by most skin types,” says Dr. Johnson. “However, at high concentrations above 5% in NAD skincare, some individuals may experience temporary flushing or mild irritation. This typically subsides as the skin acclimates to the NAD skincare product.”
Newer NAD skin care precursors have less established safety data for topical use. “Compounds like NMN and NR have good safety profiles when taken orally, but their topical use in NAD skincare hasn’t been as extensively studied,” cautions Dr. Levine. “It’s always prudent to patch test new NAD skincare products, particularly if you have sensitive or reactive skin.”
Dr. Zhang notes potential interactions: “NAD skin care precursors can enhance the penetration of other active ingredients, which might increase both efficacy and potential irritation. If you’re using prescription retinoids or acids, introduce NAD skin care products gradually to monitor how your skin responds to the combination.”
Those with rosacea or highly reactive skin should proceed with particular caution when using NAD skincare. “Start with lower concentrations and observe how your skin responds over several applications,” advises Dr. Johnson. “The temporary flushing sometimes experienced with niacinamide in NAD skin care can be more pronounced in those with rosacea.”
The Final Takeaway
NAD skincare represents a significant advancement in skincare science, targeting the fundamental cellular mechanisms of aging rather than just surface symptoms. While not a miracle solution, properly formulated NAD+ skincare offers promising benefits for maintaining skin health and addressing signs of aging at a deeper level.
“The most effective approach incorporates NAD+ skincare precursors into a comprehensive skincare regimen that includes proper sun protection, hydration, and other proven active ingredients,” concludes Dr. Zhang. “Think of NAD skincare as strengthening your skin’s foundation, enabling other targeted treatments to work more effectively.”
Dr. Levine emphasizes the importance of consistency with NAD+ skincare: “Cellular energetics and repair mechanisms respond best to steady support rather than occasional treatments. Daily application of NAD+ skincare precursors yields significantly better results than intermittent use.”
As research continues to advance, we’re likely to see increasingly sophisticated NAD skin care formulations with enhanced efficacy. “The field of NAD skin care is moving rapidly, with several clinical trials currently examining novel precursors and delivery systems,” notes Dr. Johnson. “The next generation of NAD skin care may offer even more impressive results.”
For those interested in cutting-edge skincare science, NAD skin care products merit consideration as part of an evidence-based anti-aging strategy. By supporting the skin’s fundamental cellular processes, these ingredients help maintain the skin’s resilience and youthfulness in ways that complement traditional anti-aging approaches.
