5 Expensive Products I'd Buy Again Tomorrow
I'm about to show you five of the most expensive things I own. Not the prettiest packaging, not the most Instagrammable — the ones where I looked at the price, winced, bought it anyway, and never once regretted it. Some of these are obvious. One of them isn't even beauty. By the end of this post, you'll know exactly which splurges are actually worth it, and which ones are just very convincing marketing.
Before we get into it, let's be clear about what this list is not. It's not a flex — I'm not sharing this to show off. Every single thing here had to earn its place through actual, repeated use. No impulse buys, no gifted product I felt too awkward to say no to. These are things I bought, some more than once, with my own money, at full price, and would do again without blinking.
We're going from the inside out today: supplements, to skin, to hair, to something you wear, to something you sleep on. And that last one might be the one that surprises you most. So let's start where I start every single morning, swallowing something in the name of not dying.
1. Do Not Age — The Longevity Sachet
For years, my supplement drawer looked like a small pharmacy. NMN, TMG, a SIRT6 activator, magnesium, K2 and D3, CoQ10, resveratrol, hyaluronic acid — all bought separately, all adding up, and constantly juggled because I couldn't afford to take everything I wanted, all the time.
Then Do Not Age launched this: fifteen healthy-ageing ingredients in one sachet, mixed with water, once a day. It's replacing what would have been seven separate bottles. And here's the part that actually convinced me — this sachet runs just over $200 a month. Buying those fifteen ingredients individually would run about $680 a month. I mean, who's doing that math and still buying them separately? Not me.
This isn't sponsored. I've bought Do Not Age's individual supplements for years, so when they launched this, I wasn't gambling on some unknown brand, I already trusted them. And selfishly, my favourite part is the convenience — no pill organiser, no counting capsules, I throw a handful of sachets in my suitcase and I'm done. This has already been to New York twice, and Lisbon.
I'm still taking creatine, omega-3, collagen peptides, and calcium separately, but that's a much shorter list than it used to be. Would every thirty-year-old on a basic multivitamin need this? No. But if your supplement routine has already taken over an entire shelf, this is the rare "expensive" splurge that actually saves you money on paper. It's an automatic reorder for me. No hesitation.
Now, if supplements are what I do for what's happening inside, this next category is where I obsess over what's happening on the outside: my skin.

2. Beauty Devices — Maysama AURA + MimiSilk Iris
Number two is devices, specifically two of them: the Maysama AURA Head to Heart LED combo, and the MimiSilk Iris 1450 laser.
I've tested over fifteen LED devices at this point — masks, panels, wands, all of it. The AURA dethroned my entire rotation. Both of my old systems, gone. This mask has 155 dual-core LEDs, pulse light technology, and it hugs my face in a way no rigid mask ever has. The full Head to Heart combo, face plus neck and chest, is $873. Eight hundred and seventy-three dollars, for a mask. And I'd buy it again tomorrow, full price, no code required — though obviously, use the discount code anyway.

Then there's the MimiSilk Iris, a fractional laser, which is a much bigger step up than LED. I tested it for eight weeks, and around week six, I started noticing something in my jawline I have never seen from a device before. Tighter. More defined. I'll be honest, you feel this one — it's not the watch-Netflix-while-it-works experience the AURA is. But the results earned my respect. The Iris runs $599 right now, list price $699, which puts the two devices together at just under $1,500.
And before you ask, I don't do anything in-clinic. No botox, no fillers, nothing. This is the trade I've made instead: expensive gadgets over needles.
So that's skin. But there's one area I've had to completely rethink this year, and it happened almost by accident.
3. Hair Finishing Tool — L'ange Le Duo Airflow Styler
This one has an origin story. For years, if you'd asked me, the answer here would've been the Dyson Airstrait, and it was expensive, full stop, no argument.
But I've actually been quietly using the L'ange Le Duo Airflow Styler since 2022. It's part curling iron, part flat iron — a round barrel with a clip on one side, titanium plates that use moving air instead of just static heat. I'd never used a flat iron in my life before this one, but apparently they're kinder to your hair, because the plate isn't sitting still scorching one spot, it's moving.
It retails for $119, with adjustable heat from 280 to 460 degrees Fahrenheit, and a fan that cools the hair as you style, which is apparently what actually helps a curl or wave hold. I tried a cheaper dupe first, the BaByliss Curl Styler Luxe. I loved it, until it started snagging and pulling strands out of my thin, menopausal hair. That's not a risk I can afford to take, so it's been sitting in a drawer ever since. The Le Duo has never done that to me. Not once.
Here's why it's climbing this list specifically right now: I got layers cut in recently, and layers need movement — bend, texture, volume at the root that tapers off toward the ends. That's exactly what this tool is built for. The Airstrait was built for one-length, pin-straight hair moving in one direction. Completely different job.
So it's not that the Airstrait got worse, it's that my hair changed, and the tool that's actually earning its keep right now is this one, and has been, quietly, for years. That's honestly the biggest lesson buried in this whole list: "expensive and worth it" isn't a fixed answer. It changes when you change.

Okay, from something I put in my hair, to something I put on. And this one, I feel very strongly about.
4. Solid Gold Jewellery
Number four isn't skincare or haircare at all. It's jewellery — specifically, solid gold. Not gold-plated. Not vermeil. Not gold-filled. Solid.
Here's my rule, and I'm sticking to it: I would rather own three pieces of real, solid gold than thirty pieces of plated anything. Plated jewellery has a lifespan. That gorgeous gold coating is exactly that, a coating, a few microns thick, sitting on top of brass or silver. Wear it in the shower, in the pool, against perfume or sunscreen, and eventually that coating wears through. You're left with a slightly discoloured, slightly sad, base-metal object. Vermeil is a step up, a thicker layer of gold over sterling silver, but it's still a layer. It fades. Eventually.
Solid gold doesn't do that. It's gold the whole way through. It doesn't tarnish, it doesn't flake, it doesn't turn my skin green. And unlike literally everything else on this list, it doesn't lose value the second I use it. If anything, it holds it, or gains.
Is it more expensive upfront? Astronomically. But cost-per-wear on something I'll own for the rest of my life, versus something I'll quietly replace in eighteen months, that math isn't even close.
Okay, last one, and I promise you, this is the one nobody expects.
5. The Aula Pillow — Sleep & Glow
Number five is a pillow. I know. After lasers and solid gold, we're ending on a pillow. Stay with me, because this one might be the most "worth it" thing on this entire list.
About four years ago, I started sleeping on my back, purely for vanity reasons — my chest wrinkles were getting deep, and I wanted to stop them before they became permanent. It took almost two years to find the right method and the right pillow. The one I landed on is the Aula, by Sleep & Glow.
I only sleep on silk, full stop — it's better for my hair, it's better for my skin, so the silk pillowcase upgrade wasn't optional for me. And she's not cheap. The version I have, with the premium mulberry silk pillowcase, is $295. She cradles my head so it can shift comfortably from side to side, and the neck support sits at exactly the right height.
But here's what she's done: my chest wrinkles are gone. My neck lines are nearly non-existent, which genuinely surprises people when they hear my age. And I sleep better, less tossing, less waking up with an aching neck. So when I add it up: no botox, no fillers, no in-clinic anything, and my chest and neck look the way they do because of consistent sleep positioning and the right pillow underneath it. Compared to a single clinic treatment, it's not close.
My only complaint? I can't travel with her. I actually keep a second one at my parents' house for when I visit. That's the level of commitment we're talking about.

So There They Are
Supplements, devices, hair, gold, and a pillow. Five completely different categories, one thing in common: every single one of them earned the price tag through actual, repeated, real-life use.
None of this is about having money to burn. It's about figuring out where your money actually changes something, and where it's just expensive packaging.
Now I want to know from you: what's the one expensive thing you own that you'd buy again tomorrow, no hesitation? Tell me in the comments, I read every single one.
