Timebeam vs. Timeline: Which Longevity Skincare Approach Delivers More for Less?

At some point, you start to notice it. The fine lines that weren’t there a few years ago. The firmness that isn’t quite what it used to be. Whether you’ve had a skincare routine for years or you’re just starting to pay attention, that feeling is the same.

That missing piece might not be another product. It might be what’s happening inside your cells. That’s the idea behind longevity skincare, and two brands are leading the space with very different approaches:

• Timebeam, a doctor-formulated NAD+-boosting longevity system that pairs topical skincare with a purpose-built skin supplement in a single, inside-and-out package for $77.

• Timeline, a Swiss biotech company with more than 18 years of cellular research, whose hero serum alone runs $200.

Both brands promise younger-looking skin, but the approaches, formats, and price points tell very different stories.

Comparison at a Glance

Two Paths to Cellular Skincare

The science behind these brands sounds complex, but the core idea clicks once you hear it: your skin ages because your cells lose energy over time. Both brands are trying to give that energy back. They just go about it differently.

• Timebeam focuses on boosting your body’s NAD+ (nicotinamide adenine dinucleotide), the fuel that powers every cell. By your 40s, your NAD+ levels can drop by up to 50%, which shows up as exactly the kind of dullness, fine lines, and loss of firmness most of us start noticing around that age. The NAD+ Glow Up Set uses naturally derived boosters to help replenish those levels, both on the skin and from within.

• Timeline’s skincare line is powered by Mitopure, a patented form of Urolithin A. Think of it as a cleanup crew for your skin cells: it helps clear out damaged mitochondria so they can generate energy more efficiently. The brand’s own clinical data show a 15% reduction in the appearance of wrinkles over eight weeks, with 23% improvement in hydration.

A 2026 systematic review in Ageing Research Reviews spanning 113 studies found that oral NAD+ precursors consistently demonstrate biochemical target engagement, meaning your body does respond when you give it more NAD+ building blocks. The difference is how each brand puts that science into your hands.

Where Timeline Pulls Ahead

This wouldn’t be a fair comparison without giving credit where it’s due. Timeline’s biggest strength is depth of research.

Timeline is a spinoff of the Swiss Federal Institute of Technology (EPFL), one of the world’s most respected research universities. Its Mitopure technology has been studied for over 18 years, with gold-standard clinical trials involving more than 900 participants.

The Firming Serum alone has earned nearly 1,500 verified reviews. If you’re the kind of person who reads clinical studies before buying a serum (no judgment, it’s a great habit), Timeline’s evidence base is impressive.

Timebeam is a newer brand, but that doesn’t mean it’s untested. Dr. Lamees Hamdan, the integrative medical doctor behind the brand, brings more than 20 years of experience in longevity medicine and previously co-founded Ouai with Jen Atkin.

Clinical testing on Skinbeam’s NAD+ boosting ingredient showed significant improvement in fine lines and wrinkles in just four weeks, with skin looking eight years younger by week six. An 18-year research library and a seasoned integrative MD’s clinical expertise are two different kinds of credibility, and both are worth weighing.

Why Inside and Out Matters

If you’ve ever felt like your skincare should be doing more for you, this might be the reason. A serum can only reach the outer layers of your skin. If you want to support your skin at the cellular level, what you put on your face is only part of the equation.

• Timebeam’s NAD+ Glow Up Set ($77) was designed as a single regimen. It pairs Skinbeam Milky Serum (a 3-in-1 multitasking serum that doubles as moisturizer and primer) with Bounce Mode, a lemon drop-flavored powder supplement formulated specifically as “ingestible skincare.” The serum restores and hydrates on the surface while the supplement supports cellular energy from within.

• Timeline takes a topical-only approach. The Firming Serum ($200) is designed to be used before moisturizer, not instead of it. Their supplement line (Mitopure softgels and gummies) is sold separately and marketed for general longevity, not as part of an integrated skin protocol.

If your mornings are already packed, you’ll appreciate Timebeam’s format. Just tear open a packet, let it melt on your tongue, and apply your serum.

No pills, no blender, no extra steps. One product on your face, one on your tongue, and you’re out the door.

What $77 Gets You vs. $200

Both of these brands are using real science. But when you compare serum to serum, the numbers tell a clear story.

• Timebeam’s NAD+ Glow Up Set costs $77 and includes a multitasking serum that works as your moisturizer and primer, plus a 30-day supply of a skin-specific supplement. That’s a full longevity lineup for well under half the cost of Timeline’s serum alone.

• Timeline’s Firming Serum runs $200. It’s a beautifully formulated topical treatment, but it’s designed as one step in a multi-product regimen. No supplement, no inside-and-out approach, and a separate moisturizer is still recommended. Add the Dewy Cream ($200) and you’re looking at $400 in topicals before any ingestible support enters the picture.

That’s not a knock on Timeline’s quality. It’s just a very different value equation. And if you’re the kind of person who wants your skincare investment to stretch further, it’s worth seeing the full picture before you decide.

The Moisturization Factor

Here’s a detail most comparison articles skip: what each serum expects from the rest of your routine.

Timeline’s own instructions say to apply the Firming Serum “before moisturizing.” It’s formulated as a treatment step, not a standalone. The serum does include glycerin, provitamin B5, and sodium hyaluronate for hydration, but Timeline still considers a dedicated moisturizer essential to the process.

Timebeam’s Skinbeam Milky Serum was built to carry more of the load on its own. Its NAD+ booster, peptides, and hyaluronic acid deliver hydration, firming, and priming in a single step. Pair that with Bounce Mode’s own hyaluronic acid and electrolytes, and you’re getting hydration support from both sides of the skin without adding another product to your counter.

Can you still layer a separate moisturizer over Skinbeam? Absolutely, and it’s a good option if your skin runs dry. But the point is that Timebeam gives you a choice. Timeline’s setup requires the extra step.

If you want your longevity skincare to work from both sides of the skin, prefer a routine that takes minutes instead of layers, and would rather invest $77 than $200 (or more), Timebeam’s NAD+ Glow Up Set is the stronger starting point. It’s a low-risk way to see what NAD+ can do for your skin. And with subscribe-and-save pricing at $65.45, the barrier to trying it drops even lower.

If you want the most extensively researched single ingredient in longevity skincare and budget isn’t a concern, Timeline’s Firming Serum is a solid choice backed by serious science.

Both brands are doing meaningful work in this space. But for anyone who wants clinically grounded cellular skincare that works inside and out without a $200+ entry point for a single serum, Timebeam offers a complete system that Timeline does not.

Your skin is already doing its best with what it has. Give it more to work with.
