The skincare world loves a new miracle molecule, and NAD (nicotinamide adenine dinucleotide) is the latest to get the VIP treatment. “NAD skin benefits” are splashed across high-end serums and wellness infusions, with promises of younger, stronger, and glowing skin. But are these claims all hype, or does the science actually back them up? Let’s break down the real story and bust some persistent myths about NAD in your skincare routine.
Myth #1: “NAD Serums Instantly Make You Look Younger”
Reality:
NAD⁺ is indeed vital for youthful skin, playing a central role in cell energy, DNA repair, and anti-aging enzyme activity. However, topical NAD⁺ products are only as good as their formulation. Most NAD⁺ molecules are too large and polar to penetrate the skin barrier effectively. Size and charge are the two largest reasons skincare actives cannot penetrate the skin barrier. Without an advanced delivery technology like encapsulation or functionalization, they cannot penetrate. In fact, a study found that NAD⁺ ointment required refrigeration to remain stable, and its benefits (such as reducing inflammation in psoriasis) were not dramatic “anti-aging makeovers” but rather improved skin barrier and tolerance.
Takeaway:
While NAD⁺ is crucial in the body for healthy skin, don’t expect an overnight transformation from basic NAD⁺ serums. Formulation and stability are key, and benefits will be subtle and gradual, not instant. Additionally, you should look for the evidence that supports the serum to ensure there are meaningful benefits. If you decide to purchase an NAD serum to take advantage of NADs skin benefits, make sure that you keep it refrigerated.
Myth #2: “Any NAD Product Will Boost Your Skin’s NAD⁺ Levels”
Reality:
NAD⁺ itself is a large molecule and poorly absorbed through the skin unless encapsulated or chemically modified. In contrast, niacinamide (nicotinamide), a form of vitamin B₃ and an NAD⁺ precursor, is small, penetrates skin easily. Some data shows it reliably increases NAD⁺ inside cells. This is why niacinamide shows clear anti-aging effects in multiple clinical trials, such as improved wrinkles, elasticity, and barrier strength. Newer boosters like NMN and NR theoretically penetrate better, but their effectiveness is limited without special delivery systems. Additionally, there is no robust clinical data that supports their benefits in topical skincare.
Takeaway:
If you want science-backed NAD skin benefits, look for niacinamide over NAD⁺ on the ingredient list. Niacinamide is the proven way to raise NAD⁺ in your skin.
Myth #3: “NAD Products Outperform Collagen and Other Actives”
Reality:
Collagen creams are often sold alongside NAD⁺ serums, but here’s the deal: topical collagen mostly acts as a moisturizer. It hydrates and smooths, but it cannot trigger new collagen formation because the molecule is too large to penetrate the skin. To combat this issue, scientists and cosmetic chemists have developed smaller forms and fragments of collagen that have similar functionality to the full-sized molecule.
NAD⁺-boosting actives, particularly niacinamide, can penetrate the skin barrier. Allowing them to work at the cellular level, powering DNA repair and supporting barrier health. However, large-scale anti-wrinkle effects are most reliably shown for niacinamide, not for topical NAD⁺ or collagen. Resveratrol, another trendy ingredient, can activate NAD⁺-dependent enzymes (sirtuins) and is a proven antioxidant, but it’s not a replacement for NAD⁺ itself.
Takeaway:
For barrier and anti-aging support, niacinamide, a proven NAD⁺ booster, beats topical collagen. While resveratrol offers additional antioxidant benefits, but requires NAD⁺ for its effects.
Myth #4: “NAD⁺ Injections or IVs Are Proven to Rejuvenate Skin”
Reality:
IV NAD⁺ infusions have become popular in wellness clinics, promising to “recharge” skin and body. While these infusions do raise NAD⁺ levels systemically, there are no published clinical trials specifically showing skin rejuvenation after NAD⁺ infusions. Reported benefits for skin are anecdotal, and any improvements are likely secondary to whole-body effects. High doses can cause temporary flushing, nausea, or lightheadedness. The negative effects typically resolve when the infusion is slowed or stopped. No serious long-term adverse effects have been reported, but there’s no FDA approval for any dermatological use.
Takeaway:
NAD⁺ IVs are not a shortcut to better skin, and their “anti-aging” reputation is ahead of the clinical evidence.
Myth #5: “NAD⁺ Skin Benefits Are Equal Across All Products”
Reality:
Not all NAD⁺ products are created equal. For NAD⁺ or its precursors (NMN, NR) to work, they must actually penetrate the skin barrier and remain stable in the product. The most reliable improvements in skin (like wrinkle reduction, even tone, and enhanced hydration) come from well-formulated niacinamide products. Specifically because niacinamide has a robust clinical record.
NAD⁺ serums and creams may help, but only if they use advanced stabilization and delivery systems. However, the best clinical evidence so far is for barrier and anti-inflammatory benefits, not dramatic rejuvenation.
Takeaway:
For proven results, look for niacinamide-based products and scrutinize claims about “cellular-level repair” from plain NAD⁺ serums.
Myth #6: “NAD⁺ in Skincare is Unsafe or Causes Major Side Effects”
Reality:
NAD⁺, niacinamide, NMN, and NR have a strong safety record in topical products. Clinical studies report minimal irritation for NAD⁺ ointments and niacinamide, even in sensitive skin types or conditions like rosacea. Rarely, IV NAD⁺ can cause transient side effects (flushing, nausea), but these resolve quickly. No toxic accumulation or serious adverse effects are known for topical use.
Takeaway:
NAD⁺ boosters are among the safest actives in modern skincare. Irritation is rare and usually mild.
Myth #7: “The More NAD⁺, The Better”
Reality:
Skin can only use so much NAD⁺ at a time. And more importantly, like most skincare ingredients, effective delivery matters more than sheer dose. Higher concentrations of NAD⁺ won’t help if the molecule can’t reach living skin cells due to poor formulation or instability. Niacinamide’s benefits are seen at just 2–5% concentrations in clinical trials, proving that delivery and ingredient choice matter most.
Takeaway:
Focus on well-designed formulas—especially with niacinamide—rather than the highest NAD⁺ number on the label.
The Real NAD Skin Benefits—What You Can Expect
When you cut through the hype, here’s what’s science-backed about NAD skin benefits:
- Enhanced skin barrier (less water loss, more resilience)
- Improved hydration and texture
- Reduction in fine lines, wrinkles, pigmentation, and redness (proven for niacinamide)
- Support for DNA repair and cellular energy
- Excellent safety profile, even for sensitive skin
Topical NAD⁺ and new NAD⁺-boosters are promising, but the most reliable, robust anti-aging results are still seen with niacinamide. NMN and NR may offer benefits in the future as delivery systems advance.
