Why Hollywood Can't Stop Talking About NAD+ (And What Actually Works Without a $1,000 IV Drip)

I'M FABULOUS COSMETICS · The Longevity Edit

Three of the most photographed women on the planet have gone public about the same unglamorous-sounding molecule. Here's what's actually behind the NAD+ obsession, and how to get real benefits without booking a $1,000 IV appointment.

The Molecule Hollywood Won't Stop Talking About

It started, as these things often do, with a Goop announcement. In early 2026, Gwyneth Paltrow's wellness brand launched a topical moisturizer built around NAD+, the same coenzyme that biohacker Bryan Johnson reportedly takes as a pill as part of his widely covered longevity regimen. Paltrow didn't just put her name on the product. She talked about the science behind it directly, saying the team had been "talking about emerging science around longevity and topical NAD" and that "NAD is a proven longevity tool, and it works topically as well." She's also spoken about using NAD+ IV drips herself and keeping what she's described as a personal NAD+ pen on hand for a quick boost.

She isn't the only one. Jennifer Aniston, whose skin has been a subject of public fascination for three decades, has praised weekly NAD+ shots in interviews covered by the Wall Street Journal, calling the approach "the future." And on an episode of The Kardashians, Hailey Bieber sat for an on-camera NAD+ IV drip alongside Kendall Jenner, declaring, "I'm going to NAD for the rest of my life and I'm never going to age."

Three different women, three different platforms, one recurring molecule. When a trend shows up this consistently among people who have access to literally any wellness intervention on earth, it's worth asking what's actually going on, and whether any of it applies to a normal routine and a normal budget. It's important to be precise here: these are public statements these women have made about NAD+ as a category and, in Paltrow's case, about a specific competing brand's product. None of it is an endorsement of any product sold on this site, and we're not implying otherwise. What their statements do confirm is that NAD+ has moved from a niche longevity-science topic into mainstream conversation, and that even people with unlimited access to injectables and lasers are choosing to build NAD+ into their routines.

What NAD+ Actually Is, in Plain Terms

NAD+, or nicotinamide adenine dinucleotide, is a coenzyme present in every cell in your body. It's involved in energy production, DNA repair, and the activity of a class of proteins called sirtuins, which help regulate cellular aging and stress resistance. As we get older, NAD+ levels decline. That decline is linked to reduced mitochondrial function and a general drop in how efficiently cells repair themselves.

This is not a new discovery dressed up in new marketing. NAD+ biology has been studied in longevity research for years, and it's part of why supplements like NMN and nicotinamide riboside became popular before the topical skincare version of this story even started. What's changed recently is the packaging: instead of a capsule you swallow or an infusion you sit through for hours, formulators have been working on getting NAD+ and its precursors to work directly on skin cells, where the same energy-production and repair pathways are just as relevant to how skin looks and behaves.

The IV Drip Economy: What Hailey Bieber's Appointment Actually Costs

Here's the part that doesn't usually make it into the highlight reel. NAD+ IV therapy is expensive, and not in a vague "luxury wellness" way. Sessions typically run $299 to $1,396 depending on dosage, with a 250mg dose landing around $250 to $429, a 500mg dose around $399 to $698, and a full 1000mg dose reaching $599 to $1,396 at many clinics. In major cities, expect to pay toward the higher end of that range, often $600 to $1,000 per visit. Mobile IV services that come to your home or hotel add another $200 to $400 on top. Loading packages of four to six sessions, which some clinics recommend for a proper "reset," run $1,500 to $6,000. And because NAD+ IV therapy has no FDA-approved medical indication, insurers treat it as elective wellness care. Medicare and Medicaid don't cover a dollar of it.

Then there's the time cost. A single NAD+ infusion isn't a quick in-and-out appointment. The slow drip is intentional, designed to maximize absorption and minimize nausea and flushing, and it typically takes two to four hours per session, sitting in a chair with a needle in your arm.

None of this is a criticism of anyone who chooses to do it. If the budget and the time exist, an NAD+ IV protocol may well have benefits worth exploring with a qualified provider. But it also explains why "start using an NAD+ serum" is a more realistic entry point for the overwhelming majority of people who read a headline about Jennifer Aniston's weekly shots and think, understandably, "I am not doing that."

Does a Topical NAD+ Serum Actually Do Anything?

This is the honest question, and it deserves an honest answer rather than a marketing one. The skin's outer layer, the stratum corneum, exists specifically to keep things out. Any topical ingredient, including NAD+, has to overcome that barrier to reach the living layers where collagen is produced and cellular repair actually happens. That's a real formulation challenge, and it's why not every NAD+ product on the market is created equal.

The clearest evidence sits with niacinamide, an NAD+ precursor and one of the most extensively studied ingredients in cosmetic dermatology. Multiple randomized, vehicle-controlled clinical trials have shown that topical niacinamide, typically at concentrations of two to five percent, produces measurable improvements in fine lines, wrinkles, tone, redness, and texture over eight to twelve weeks. That's not a marginal footnote. It's one of the more consistently replicated findings in the ingredient world.

Beyond niacinamide, direct topical NAD+ and complementary antioxidants like resveratrol work on a related but distinct front: supporting the cellular energy and sirtuin pathways that decline with age, and defending against the oxidative stress that accelerates visible aging. Preclinical research on fibroblasts, the collagen-producing cells responsible for skin firmness, has shown protective effects against both UV stress and intrinsic aging signals when NAD+ availability is supported. Human clinical data on this specific mechanism is still developing, which is a fair caveat to make. But the mechanistic rationale is unusually strong for a cosmetic ingredient story, and it's why serious formulators keep returning to it. We covered the underlying science in more depth in our full breakdown of NAD+ topical serums and wrinkle reduction, for anyone who wants the deeper clinical detail.

The Sirtuin Connection: Why Longevity Scientists Care About This Beyond Skin

To understand why NAD+ generated enough momentum to reach Goop, a Kardashians storyline, and a Wall Street Journal interview all in the same cultural moment, it helps to zoom out from skincare entirely. NAD+ is central to the activity of sirtuins, a family of proteins that regulate cellular aging, DNA repair, and stress resistance across essentially every tissue in the body, not just skin. This is the same biology that underpins Bryan Johnson's widely publicized longevity protocol and a wave of academic research into extending healthspan. When NAD+ levels decline with age, sirtuin activity drops along with it, and cells become measurably less efficient at repairing daily damage.

Skincare is, in a sense, riding on the coattails of a much larger scientific story. Dermatology didn't invent interest in NAD+; longevity researchers did, years earlier, studying it in the context of metabolic health, muscle function, and cognitive aging. What's happened more recently is that cosmetic chemists asked a reasonable follow-up question: if NAD+ decline is part of what makes tissue age throughout the body, does supporting it locally, at the skin's surface, produce any of the same benefits we're seeing described in longevity literature? That's a legitimate scientific question, and it's the one our formula, along with the broader NAD+ skincare category, is built to explore.

Why Resveratrol Is the Quiet Partner in This Story

NAD+ rarely appears alone in a well-formulated serum, and there's a reason for that. Resveratrol, the polyphenol famous for its association with red wine and longevity research, is a potent antioxidant that helps defend skin cells against the environmental and oxidative stress that depletes NAD+ in the first place. Pairing the two ingredients is less about stacking buzzwords and more about addressing both sides of the same problem: NAD+ supports the cell's energy and repair machinery, while resveratrol helps protect that machinery from the damage that wears it down day to day.

Our NAD+ Resveratrol Collagen Serum is built around exactly this pairing, combined with plant-based collagen boosters and niacinamide, formulated to work on both fronts at once rather than isolating a single trendy ingredient and hoping it carries the whole formula.

What's Actually in the Bottle

Transparency matters more in this category than almost any other, because "NAD+" has become a word brands slap on packaging without necessarily backing it with a formulation that makes sense. Our NAD+ Resveratrol Collagen Serum lists Nicotinamide Adenine Dinucleotide, Resveratrol, and Niacinamide as its lead actives, alongside 3-o-Ethyl Ascorbic Acid, a stable vitamin C derivative, Sodium Hyaluronate for hydration, Aloe Vera and Seaweed Extract for soothing and mineral support, Collagen, and Rosemary extract as a natural preservative and antioxidant. The full ingredient breakdown and sourcing philosophy for every formula we make is available on our ingredients page, for anyone who wants to read past the marketing copy.

"The most honest answer is that you can reduce the appearance of fine lines, improve brightness, and support elasticity with a serum that increases NAD+ availability through well-tested precursors like niacinamide, alongside emerging strategies that stabilize NAD+ itself."

How to Actually Use an NAD+ Serum

Apply two to three drops to clean, dry skin morning and night, gently massaging in until fully absorbed, then follow with moisturizer. In the morning, sunscreen is non-negotiable; no NAD+ formula, however well made, outpaces daily unprotected UV exposure. The visible arc of change tends to be progressive rather than instant. Hydration and glow often improve within days. Texture refinement and a reduction in redness tend to follow over the next few weeks. Fine lines and evenness of tone are the slowest to shift, typically assessed at the eight to twelve week mark, which is the same window used in the clinical trials behind niacinamide.

Layering NAD+ With the Rest of Your Routine

One question we hear constantly: does an NAD+ serum replace peptides, or work alongside them? The honest answer is that they solve different problems. NAD+ and resveratrol target cellular energy metabolism and oxidative stress, the deep biological drivers of aging. Peptides like SNAP-8 work more mechanically, reducing the muscle-contraction patterns behind expression lines, while GHK-Cu signals collagen remodeling and skin repair. Many of our clients layer an NAD+ serum with a peptide serum in the same routine, applying the lighter, faster-absorbing NAD+ formula first, letting it fully absorb, then following with the peptide serum before moisturizer. This isn't redundant. It's addressing energy metabolism, oxidative stress, muscle-related lines, and structural collagen support in a single short routine, which is closer to what a comprehensive longevity-minded skincare approach actually looks like.

Why the Celebrity Trend Is Worth Paying Attention To, Carefully

There's a version of this article that leans entirely on name-dropping and calls it a day. That's not useful to you, and it's not honest about how these things actually work. What's genuinely useful about the Paltrow, Aniston, and Bieber moment is not that a famous person uses a product, it's that the wellness and dermatology industries have converged on the same molecule from very different directions at the same time. Longevity researchers have been studying NAD+ decline for over a decade. Cosmetic chemists have been separately working on niacinamide, an NAD+ precursor, for even longer, with a strong independent clinical track record. IV therapy clinics found a wealthy, motivated customer base willing to pay for infusions. And skincare brands, including Goop and including us, have been working on getting the same underlying biology into a topical formula that doesn't require a needle.

When three separate industries converge on the same ingredient from three different angles, that's a meaningfully different signal than a single influencer partnership. It doesn't mean every claim made about NAD+ is proven. It means the underlying interest is coming from people with genuinely different incentives, which is a more reliable sign that there's something real here worth understanding, not just something trendy worth ignoring.

What NAD+ Skincare Can't Do

In the interest of not overselling this the way a celebrity headline might: a topical serum, however well formulated, is not a substitute for an IV infusion in terms of systemic effect, and it is definitely not a substitute for Botox, a facelift, or laser treatment if that's the specific correction you're after. NAD+ skincare works on the skin's own cellular processes over weeks, not instantly, and it works best as part of a full routine that includes sunscreen, hydration, and barrier support, not as an isolated miracle step. If a brand promises overnight, dramatic transformation from any NAD+ product, that claim should raise an eyebrow regardless of who's fronting the marketing.

A Realistic Way to Think About the Investment

Here's a useful way to frame the math. A single NAD+ IV session at the low end of the price range, roughly $300, buys one afternoon's worth of infusion. A 30ml bottle of a well-formulated NAD+ topical serum, used twice daily as directed, typically lasts one to two months of consistent use, meaning the cost compares favorably even before accounting for the fact that IV therapy is usually recommended in repeated sessions or loading packages to maintain any benefit. This isn't a claim that the two deliver identical results, because they work through different delivery routes and different magnitudes of exposure. It's simply an honest comparison of what's financially and logistically realistic for most people building a long-term routine, versus what's realistic as an occasional splurge.

How This Compares to a Standard Vitamin C or Retinol Serum

A reasonable question, if you already have a vitamin C serum or a retinol in your routine: why add another active category on top of what's already working? The answer is that NAD+, vitamin C, and retinol are not competing for the same job. Vitamin C is primarily an antioxidant and brightening agent that also supports collagen synthesis. Retinol accelerates cell turnover and directly stimulates collagen production, but often comes with irritation and sun sensitivity that requires careful management. NAD+ and resveratrol work on cellular energy metabolism and oxidative defense, a layer beneath what either vitamin C or retinol directly addresses. In practice, this means an NAD+ serum tends to layer well alongside a vitamin C routine in the morning, or can be used as the primary active on nights when retinol would otherwise be too aggressive for the skin to tolerate. It's a complement to a strong routine, not a replacement for the actives already doing established work in it.

A Note on Realistic Expectations vs. Influencer Claims

Search "NAD+" on any social platform and you'll find claims ranging from reasonable to absurd, everything from "supports cellular energy" to "reverses aging by a decade." It's worth being the skeptical reader here. NAD+ decline is real, well documented in aging biology, and connected to reduced repair capacity in cells. Topical niacinamide's benefits for fine lines and tone are backed by genuine, repeated clinical trials. Direct topical NAD+ and resveratrol's specific contribution is promising in preclinical and mechanistic research, but represents a newer, still-developing body of evidence compared to niacinamide's decades-long track record. Holding both of those facts at once, genuine promise and appropriately calibrated expectations, is the difference between an informed skincare decision and one driven purely by a headline about a celebrity IV drip.

Who Should Consider an NAD+ Serum

This category tends to resonate most with people who are already paying attention to skin longevity rather than reactive correction, people managing dullness, uneven tone, or the early, cumulative signs of fatigue in the skin rather than deep static wrinkles, and people who want their skincare routine to be grounded in the same cellular-aging science that's driving the broader longevity movement, without committing to injectables or IV appointments to get there. It's also a natural fit for anyone already using our peptide line who wants to add a layer that addresses energy metabolism and oxidative stress rather than muscle activity or collagen signaling specifically.

What to Expect in the First Month

Week one typically brings a noticeable hydration and glow improvement, especially if your skin has been feeling dull or fatigued. By weeks two to four, most people report smoother texture and a calmer overall look, particularly around areas prone to redness. It's worth resisting the urge to judge the serum on day three; the collagen-related and tone-evening benefits documented in clinical literature on niacinamide, the best-studied component of this formula category, consistently show up in the eight to twelve week range, not the first week. Consistency, not intensity, is what the research actually supports.

The Broader Skin Longevity Context

NAD+ doesn't exist in isolation from the rest of the skin longevity conversation. It's part of a broader shift in how skincare brands and consumers are thinking about aging, less about correcting a single wrinkle and more about supporting the underlying cellular processes that determine how skin behaves over years, not days. We've written previously about how NAD+ pathways intersect with biohacking and hair growth trends in this piece on NAD+ as a longevity tool, and for readers building out a fuller peptide-and-longevity routine, our Syn-Ake Peptide Serum pairs well as a separate, muscle-targeted addition for anyone who wants to address expression lines alongside cellular energy support.

Building NAD+ Into a Daily Routine

If you're starting from scratch, simplicity beats complexity. Cleanse, apply the NAD+ serum to clean, dry skin, let it absorb fully, then moisturize, and finish with sunscreen in the morning. If you're layering with peptides, add that step between the NAD+ serum and moisturizer. We've outlined a more detailed version of this sequencing in our guide to incorporating NAD+ into a daily skincare routine, including how to introduce it gradually if you have reactive or sensitive skin.

Common Questions Before You Start

A few questions come up consistently when people first consider adding NAD+ to their routine, beyond the ones already covered in the FAQ section below. Can you use it if you're also getting Botox or filler? Yes, there's no known interaction between topical NAD+ and injectables, and many people specifically use a longevity-focused topical routine between injector appointments to support skin quality in the weeks the clinic can't reach. Can you use it during pregnancy or while breastfeeding? As with any active skincare ingredient, that's a conversation to have directly with your physician, and we'd point you to our medical disclaimer for the full context on how we frame these recommendations. Is it safe for sensitive skin? The formula is designed to be gentle, but as with introducing any new active, patch testing on a small area for a few days before full application is the sensible approach.

Why We Built This Formula the Way We Did

When NAD+ started showing up across wellness media, the temptation for a lot of brands was to throw a small percentage of the ingredient into an existing formula and slap a new label on it. We took a different approach, building the NAD+ Resveratrol Collagen Serum around the pairing that actually makes biological sense: NAD+ and niacinamide for cellular energy and precursor support, resveratrol for the antioxidant defense that protects that process, and plant-based collagen and hyaluronic acid for the hydration and structural support that makes any anti-aging serum feel complete rather than clinical. It's part of a broader set of formulations we've developed around skin longevity as a category, which you can explore in full on our skincare protocols page.

Frequently Asked Questions

Do celebrities actually use NAD+, or is this just marketing?
Several have gone on record about it directly. Gwyneth Paltrow has discussed using NAD+ IV drips and a personal NAD+ injection pen, and Goop launched its own topical NAD+ moisturizer in 2026. Jennifer Aniston has publicly praised weekly NAD+ shots. Hailey Bieber received an on-camera NAD+ IV drip with Kendall Jenner on The Kardashians. These are public statements about NAD+ as a category, not endorsements of this or any specific product.

What's the difference between an NAD+ IV drip and a topical NAD+ serum?
An IV drip delivers NAD+ directly into the bloodstream over two to four hours, typically costing $299 to $1,396 per session. A topical serum is applied daily and works locally on skin cells. They're built on related science but aren't interchangeable.

Can a topical NAD+ serum actually reduce wrinkles?
The strongest evidence sits with niacinamide, an NAD+ precursor, which has repeatedly shown measurable improvements in fine lines, tone, and texture in controlled trials over eight to twelve weeks.

How long until I see results?
Hydration and glow often improve within days. Texture and tone improvements are typically assessed at the eight to twelve week mark, consistent with the clinical research timeline.

Can I use it with peptides like SNAP-8 or GHK-Cu?
Yes. NAD+ and resveratrol target cellular energy and antioxidant defense, while peptides target muscle activity and collagen signaling. Many routines layer both, applying the lighter NAD+ serum first.

The Bottom Line

The Hollywood NAD+ moment is real, well documented, and grounded in genuine, if still-developing, science, not empty influencer marketing. Gwyneth Paltrow, Jennifer Aniston, and Hailey Bieber have each spoken publicly about NAD+ in their own words, through very different formats, from an on-camera IV drip to a branded moisturizer launch. None of that is a claim that any of them uses this specific serum, and we're not suggesting otherwise. What it does confirm is that the underlying interest in NAD+ as a longevity and skin ingredient is real, and that the topical, needle-free version of that story, built on the well-established science of niacinamide alongside NAD+ and resveratrol, is the version most people can actually build into a sustainable routine without a $1,000 line item on their credit card statement.

If the idea of NAD+ has been sitting in your head since the last time you saw a headline about it, you don't need an IV appointment to find out whether it's worth your attention. You need two to three drops, twice a day, and about eight weeks of consistency, applied with the same patience you'd bring to any active ingredient that's actually doing something rather than promising everything overnight.
