My 12 Week Results With the Tria 4X Laser Hair Removal Device
Twenty years ago I convinced myself the Tria Laser didn’t work. Turns out, I may have just had absolutely no idea what I was doing.
It hurt so badly, took forever, and after spending what felt like an absurd amount of money on a beauty device at the time, I wanted so badly for it to work. Instead, I would use it for a few weeks, stop, convince myself it wasn’t doing anything, then randomly pull it back out months later and start all over again.
This before and after was the moment I realized the Tria was actually working.
So when Tria reached out about trying the Tria 4X Laser Hair Removal Device again, my reaction was honestly mixed. Part of me immediately remembered sitting on the bathroom floor twenty years ago psyching myself up to laser one tiny square inch of skin at a time. I had also recently tested another at-home hair removal device with pretty sad results, so I almost said no altogether.
But the weird thing was, I still couldn’t fully let go of the idea that maybe the problem hadn’t been the laser. Maybe I just didn’t understand yet how much consistency, timing, coverage, and honestly pain tolerance affected whether this kind of device actually worked in real life.
So I tested the Tria again for 12 weeks to see whether at-home laser hair removal could actually reduce thick hair long term — and the before and after photos completely changed my opinion of this device.
Why I Think My First Experience with the Tria Failed
I was doing everything wrong. I would forget where I had already lasered. I would accidentally go over sections twice, then miss entire areas because the process took so long. Then eventually I’d stop altogether once i reached my pain threshold.
The biggest issue was that I never followed the instructions correctly. This is not supposed to be a daily — or even weekly — chore. The Tria is only meant to be used every other week, and twenty years ago I genuinely did not understand that more often was not better.
Back then I didn’t know the first thing about hair cycles, or that laser hair removal is really a long game. Different hairs are actively growing at different stages, so the point is not to laser yourself constantly — it’s to stay consistent enough to gradually catch follicles during active growth cycles over time.
Turns out you can’t girlboss your way around hair cycles. All I was doing was making the process more painful, more exhausting, and honestly much harder to stick with consistently.
What the Tria 4X Actually Feels Like to Use
When I say this device hurts, it really does hurt. It feels like a rubber band being snapped back a hundred times. Unfortunately, that makes it take longer to do because breaks are needed. And worse, the motivation to continue wains fast
But honestly, this is also the tradeoff of using a true diode laser instead of a gentler IPL-style device. The Tria is much closer to professional laser hair removal technology, which probably explains both the pain and why the results eventually felt much more noticeable to me.
The Numbing Cream Trick That Changed Everything
But then I remembered I already use numbing cream when I microneedle. Why wasn’t I approaching this the same way?
So I did.
And honestly, numbing cream completely changed my experience with the Tria. Once I removed most of the pain from the equation, I suddenly became far more methodical with the device. I stopped losing track of where I had already lasered, moved faster, covered more area properly, and most importantly, I stayed consistent because it no longer felt like a torture device every time I picked it up.
Looking back, I genuinely think pain was one of the biggest reasons I failed with the Tria the first time around. I was so focused on just getting through it that I wasn’t actually using the device carefully or consistently.
My personal routine was using numbing cream and letting it sit for about an hour before the Tria laser hair removal so it had time to fully kick in. After that, I could comfortably do my legs, bikini line, and underarms all in one session — which would have sounded absolutely insane to me twenty years ago.
However, if you don’t have crazy sensitive skin like I do, they do carry a soothing gel that really does help! Just apply it before you start. And also, your skin really does develop a tolerance over time and hurt less the more you do it.
The Biggest Mistake I Made with the Tria 4X
Now that I’ve used this device as a mature adult, I’m starting to wonder if the 20s version of me even read the instructions. I remember the instructions saying something about the hair follicle cycle but my brain definitely interpreted that as “use daily and get the hairs to die faster!” Not only was I overdoing it, but I wasn’t giving it more than a cycle before giving up. I’m positive I wasn’t patient in timing or coverage. I was wasting my time while drying out my skin.
Why You Only Need to Use At-Home Laser Hair Removal Every 2 Weeks
I’m ashamed to admit I didn’t have my a-ha moment until 2 weeks in when I realized the instructions said to laser once every 2 weeks. Once I started following this routine I started seeing my hairs getting finer, and some hairs stopped growing back altogether. My progress with the Tria Hair Removal Laser 4x never felt fast, in fact, it wasn’t until I looked at my photos I even noticed what a difference the Tria had made.
I think with how thick my hair follicles are I may need a little longer than some people, but it works. Pictures don’t lie. All I did was finally follow the instructions to interrupt the hair cycle at the right time with a dash of patience, consistency, and methodical coverage.
The Tria Feature I Completely Ignored the First Time
Another thing I completely ignored the first time around was the calibration scanner.
Before you can start a treatment, the Tria has you scan the area you actually plan to laser with a skin sensor. Twenty years ago I basically treated that step like a suggestion. I figured skin is skin, my Fitzpatrick type is still my Fitzpatrick type, so what difference could it possibly make if I scanned my leg before doing my underarms?
Apparently not.
Back then I would casually scan my sun-kissed legs before treating my ghostly underarms and somehow never considered that those might register differently. The second I actually started scanning the area I planned to treat with my accurate skin tone, I could immediately tell the device behaved differently.
Looking back, I think I approached the original Tria with the confidence of someone assembling IKEA furniture without the instructions. I was absolutely freelancing the experience. Overusing it, skipping steps, randomly lasering sections twice, then wondering why I wasn’t getting the results I expected.
The second time around, once I actually slowed down and followed the protocol correctly, the entire experience changed.
Why Timing Matters with Laser Hair Removal
One thing I also started noticing was that my pain tolerance seemed to change depending on where I was in my cycle.
There were some treatment weeks where I barely felt the laser at all, then other weeks, especially around my period, where I suddenly felt much more sensitive. The numbing cream helped tremendously, so it never became unbearable again, but I could still tell there was a difference.
Looking back, I probably would have made my period week my “off” week from the beginning. The Tria already requires consistency and patience, and anything that makes the process feel mentally easier is probably going to help you stick with it long term.
Tria 4X vs IPL: Why This Device Feels Different
Another thing I also did not understand twenty years ago is that the Tria is not IPL.
Most at-home hair removal devices use IPL (intense pulsed light), which tends to feel broader, gentler, and more “flashy” for lack of a better word. The Tria actually uses a diode laser, which is much closer to the type of technology used in professional laser hair removal offices.
Which honestly explains a lot.
It explains why the Tria hurts more. It explains why the treatment window is so tiny. And it explains why the results eventually started getting really good once I actually used it consistently.
The diode laser also targets the follicle much more directly than typical IPL devices, which probably explains why the experience feels more intense overall. The tradeoff is that treatments can feel slower and less glamorous, but the results eventually started feeling far more noticeable to me than the IPL devices I had previously tried.
And interestingly enough, randomized trials comparing diode lasers and IPL devices have generally found diode lasers more effective for long-term hair reduction, although also more painful — which honestly explains a lot about my experience with the Tria.
My 12 Week Tria 4X Before and After Results
The biggest difference wasn’t perfectly hairless skin. It was when the regrowth stopped looking dense and started looking scattered.
It was these photos that made me know I want to keep going.
Seeing the before and after photos side by side honestly changed my entire perspective on the Tria. For the first time, I could clearly see that the issue twenty years ago probably wasn’t that the device didn’t work. It was that I wasn’t using it consistently or correctly long enough to let the process actually build on itself.
And weirdly, talking to friends who still go back for professional laser touch-ups has made me even more appreciative of having an at-home option. Even professional laser still has to work around hair growth cycles and repeated sessions over time, so there’s something incredibly convenient about being able to do maintenance from your own bed instead of scheduling your life around appointments.
Does the Tria 4X Actually Work?
Is the Tria fast? Absolutely not. Is it painless? Also no. But it ended up being far more effective (and more cost effective) than I remembered once I finally stopped trying to brute-force the process and started working with it instead.
I don’t think the Tria is the kind of beauty device people impulsively fall in love with—it’s not exactly the most fun way to spend my time (unless you’re a sadist of course). But somewhere along the way, I realized I have no clue when I shaved last and started getting oddly excited to finish off the stragglers. And honestly? My bikini line has never looked better heading into summer.
If you decide to brave the Tria yourself, you can use code VANILLA for a discount.
