One of the most critical cellular coenzymes, present in every living cell and central to longevity science, especially as its natural levels decline with age. It helps support skin cell energy production - supporting skin cell renewal, addressing visible skin damage and restoring skin health. By enhancing healthy skin cell function over time, NAD+ helps with environmental and age-related damage, addressing multiple emerging & visible existing signs of aging simultaneously and rewinding the appearance of your skin’s age for a more youthful look.

A naturally occurring biomolecule in the body, NMN serves as a direct precursor to NAD+, meaning it can help the body replenish NAD+ within skin cells over time. By helping restore NAD+ levels, NMN helps assist natural longevity pathways and boosts skin cell function and vitality, promoting a healthier, more youthful-looking complexion.

A multitasking active and stable form of vitamin B3, Niacinamide acts as a booster-precursor to NAD+, supporting the body’s natural NAD+ production. It helps fuel skin cell energy, strengthen the skin barrier, even skin tone, enhance moisture retention, and promote visible skin renewal. In synergy with NAD+ and NMN, Niacinamide helps sustain a continuous energy supply to skin cells while reinforcing skin longevity – for a smoother, stronger, and more resilient complexion.

- Anti-aging & wrinkle reduction → Supports collagen and elastin production while reducing breakdown, leading to firmer, smoother skin with fewer fine lines.
- Improved barrier repair → Enhances lipid and ceramide synthesis, which strengthens the skin’s protective barrier, reduces sensitivity, and improves hydration.
- Increased radiance & glow → increased cellular energy and faster turnover help skin look brighter and more even-toned.
- Enhanced resilience →  improve recovery from environmental and oxidative stress, leading to less dullness and damage over time.
- Calmer, healthier-looking skin → NAD+ can positively influence inflammation pathways, helping reduce redness, irritation, and signs of stressed skin.

NAD+(nicotinamide adenine dinucleotide) and niacinamide are closely related but not the same. NAD+ is a coenzyme inside every cell that acts like cellular fuel, powering energy production, DNA repair, collagen maintenance, and defense against stress – but its levels naturally decline with age. Niacinamide, on the other hand, is a stable, skin-penetrating form of vitamin B3 that serves as a precursor, meaning skin cells can use it to make more NAD+ through their natural pathways. This makes niacinamide highly effective in skincare, not only for boosting NAD+ but also for improving barrier function, calming inflammation, evening skin tone, and reducing visible pores. In short, NAD+ is the “fuel,” while niacinamide is one of the key building blocks the skin uses to keep that fuel tank full.

Yes. NAD+ and its precursors (like niacinamide, NMN, or NR) are generally considered safe for sensitive skin and for daily use, especially compared to stronger actives like retinoids or exfoliating acids. Because NAD+ works by replenishing a natural coenzyme already present in every cell, it doesn’t act as an irritant; instead, it tends to support barrier repair, hydration, and cellular resilience, which can actually help calm sensitivity over time.
That said, a few caveats:
1. Formulation matters → Pure NAD+ is unstable and large, so effective products usually use stabilized NAD+ or precursors; these are typically well tolerated.
2. Concentration → High-dose niacinamide (above ~10%) can sometimes cause flushing or tingling in sensitive skin, but this is rare with NAD+ serums that use balanced formulations.
3. Daily use is usually safe, and many products are designed for AM/PM application.
Bottom line: NAD+ is considered a gentle, barrier-supportive active suitable for daily use, even on sensitive skin, but–as with any new ingredient – patch testing is recommended.

You’ll typically notice the most immediate results of NAD+ serums in areas where the skin barrier is thinner, more stressed, or prone to dehydration. Many people first see improvements in the cheeks and forehead, where increased hydration and radiance show up quickly as a healthier glow. Around the eyes, NAD+ can support smoother texture and reduce the appearance of crepiness or fine lines. The nasolabial folds and mouth area may feel softer and more supple as barrier function strengthens. Overall, the earliest visible changes are usually in hydration, smoothness, and brightness, while deeper structural benefits like firmness and wrinkle reduction take more time.

Yes. NAD+ is strongly preventative because it helps skin cells maintain the cellular energy and repair capacity they naturally lose with age. NAD+ fuels key processes like DNA repair, antioxidant defense, and collagen maintenance, which means keeping levels higher can slow the accumulation of cellular damage that leads to visible aging. While ingredients like retinoids or acids often correct existing issues (wrinkles, uneven texture, discoloration), NAD+ works more like a cellular insurance policy: it strengthens the skin barrier, supports resilience, and helps cells function, so signs of aging and stress appear more slowly. In short, NAD+ not only improves current skin texture and quality but also helps support long-term skin longevity, helping delay future damage and visible signs of aging.

NAD+ serums are gentle and versatile, making them easy to incorporate into both morning and evening routines. They can be applied after cleansing and before heavier treatments or moisturizer, following the general rule of layering from thinnest to thickest textures. In the morning, NAD+ helps boost defenses against environmental stressors and pairs well with vitamin C, while in the evening it supports skin cell renewal alongside retinol. For best results, most people use an NAD+ serum twice daily, followed by moisturizer and sunscreen in the morning.

A NAD+ serum isn’t meant to replace your entire anti-aging routine but to complement it by working at the skin cell level to enhance energy and help skin appear more youthful.
While NAD+ strengthens resilience, improves barrier function, and makes other actives work more efficiently, it doesn’t duplicate their specific benefits: retinoids still drive skin cell turnover and support natural collagen synthesis, vitamin C delivers direct antioxidant and brightening effects and exfoliating acids resurface texture and tone.
In this sense, NAD+ is best thought of as the “power supply” behind your other treatments, enhancing their performance while providing its own anti-aging, barrier-supportive, and radiance-boosting benefits.
