I’ve been testing the TRIA 4x laser hair removal device at home and am sharing my brutally honest thoughts. I’ll continue to update this post with my progress, so bookmark this page and check back!

The struggle is real when it comes shaving and waxing, so I finally decided to commit to laser air removal. I’m sharing what laser actually is versus IPL, what it costs compared to everything else, how the Tria 4X works and my experience using it. Fall is also the perfect time to start because you want to avoid sun exposure when doing laser hair removal.

Why I Chose At-Home Laser Hair Removal

• Saves money: A single Tria device runs about $600 once, versus thousands of dollars in professional laser sessions over the same number of treatments.
• No appointments and the comfort of at-home privacy: I do it on my own schedule, in my own home without having to drive in traffic and find parking.
• Actual laser, not IPL: I wanted real diode laser technology rather than the broader, less targeted light most drugstore devices use.
• Less irritation than waxing: No pulling hair from the root every few weeks, no ingrown hairs, no razor burn.
• It fit my skin and hair type: I checked that I was in the right Fitzpatrick range and had dark enough hair before committing, since it doesn’t work for everyone.
• Long-term results: Results are permanent, with maintenance sessions needed.

No More Strawberry Legs and Razor Bumps!

If you’re like me and have strawberry legs (those small pink or dark bumps on your skin), it turns out it was never genetics. It’s actually a hair removal method problem: razor bumps happen when a shaved hair curls back into the skin, and strawberry legs are the follicles themselves (plus trapped debris and oil) showing through as dark dots. The follicle is still fully intact under your skin, so shaving doesn’t touch it, and waxing pulls the hair but leaves the follicle able to grow a new one within days, so you never actually solve the root of the problem literally. Laser targets the follicle directly, using a wavelength absorbed by the melanin in the hair to heat and disable it so the hair falls out for good, which means no more strawberry legs!

IPL vs Laser

It’s important to know that IPL and laser are two different methods of hair removal. IPL stands for intense pulsed light — it puts out a broad spectrum of wavelengths all at once, rather than one targeted wavelength. Because it’s scattered across such a wide spectrum, a lot of that light doesn’t do anything useful to the hair follicle at all, and less energy actually reaches the root. Laser, on the other hand, uses a single precise wavelength tuned specifically to be absorbed by melanin in the hair (810nm for Tria). More of the energy goes exactly where it needs to.

IPL tends to top out around 58–74% hair reduction after roughly 12 sessions, and even then it’s temporary because you need regular sessions to maintain it. Laser can get to up to 100% hair reduction, and with enough consistent treatments, that reduction can become permanent.

Does At-Home Laser Hair Removal Really Work?

Yes, at-home devices do work to reduce hair growth over time, but they’re less powerful than professional clinic machines and demand real consistency to see results. Most home systems use IPL (Intense Pulsed Light) rather than a true medical-grade laser, which stuns the follicle to slow regrowth rather than destroying it outright.

Realistic results you can expect without sugarcoating anything:

• Hair reduction, not elimination: hair gets noticeably finer and sparser after a few weeks of consistent use.
• Not permanent on its own: you’re looking at long-term reduction, which means occasional maintenance sessions down the line, not a one-and-done fix.
• Contrast matters: these only work well with high contrast between skin and hair — light skin paired with dark brown or black hair. Blonde, red, gray, or white hair just won’t respond.

Home vs. professional:

• Cost and privacy win for home devices: it’s significantly cheaper, and you can do it on your own couch instead of having to drive somewhere.
• Lower speed and power: treatment windows are smaller so sessions take longer, and the lower energy output means it takes more time to see the same results a dermatologist’s office could give you faster.

For reference, the independent clinical study behind Tria 4X found (21 participants, self-assessment scores) up to 61% hair reduction after just 1 treatment, up to 75% after 2 treatments, and up to 100% hair reduction after 8 treatments.

Laser Hair Removal Cost vs Other Options

• Tria 4X (at-home laser): $599.99, one time. Permanent results, up to 100% hair reduction in 8 treatments.
• In-clinic laser: $2,000–$5,000 for a full 8-session course. This uses essentially the same technology as Tria 4X — a precise wavelength, usually in the 800–810nm range, targeting the follicle at the root — just at higher power and with a much higher price tag, since you’re paying for the equipment and the provider’s time and expertise.
• IPL devices: $150–$1,000 one time, but because IPL only offers temporary results you need ongoing sessions.
• Waxing: an estimated $8,000–$23,000 over a lifetime, for a method that only ever produces short-term, temporary results and has to be repeated on a strict schedule to keep hair away.
• Shaving: an estimated $3,000–$10,000 over a lifetime — cheaper than waxing, but still purely temporary, has to be done constantly, and comes with its own list of downsides (irritation, ingrown hairs, nicks).

What Is Tria 4X?

Tria 4X is an at-home laser hair removal device, and it’s currently the only FDA-cleared laser for permanent hair reduction available for home use. Meanwhile a lot of “laser” devices sold for home use are actually IPL, which is a different technology with a different (temporary) result.

The specs: it runs at a precise 810nm wavelength, which is the specific “hair-targeting” wavelength that gets absorbed by melanin in the hair. It delivers up to 233% more power than leading IPL devices.

How It Actually Works

The mechanism is pretty simple once you break it down into steps:

1. The laser beam targets the hair follicle at the root, without damaging the surrounding skin.
2. That laser energy is absorbed by the melanin inside the hair, which heats up the follicle.
3. The heat disables the follicle, and the hair falls out.
4. After multiple treatments, this process can become permanent — the follicle stops producing new hair.

This is also why laser (unlike shaving or waxing) can actually break the cycle instead of just resetting it. Shaving cuts the visible hair but leaves the follicle completely untouched, so regrowth is immediate. Waxing pulls hair from the root but doesn’t damage the follicle itself, so it just grows a new hair back over the following weeks. Laser is the only one of the three that’s actually going after the thing producing the hair in the first place.

How to Get the Best Hair Removal Results

Here’s what you should know if you want to get the best results:

• Shave, don’t wax or pluck, beforehand: shave 24 hours before each session so the follicle stays intact — waxing or plucking removes exactly what the laser needs to target.
• Avoid sun and self-tanner for two weeks prior: both interfere with the laser’s ability to accurately target hair pigment, and sun exposure raises burn risk.
• Skip active skincare the day of treatment: retinol, acids, and oils increase skin sensitivity and can block laser penetration.
• Patch test first: especially important the first time you use it, 24 hours before your full session.
• Stick to the schedule: treat every 2 weeks, consistently, for 6–8 sessions and DO NOT SKIP sessions and don’t over do it either!
• Use the right setting for you: lower settings (1–2) are more comfortable, higher settings (4–5) give stronger results — work up as your skin tolerates it.
• Overlap each pulse slightly: track where you’ve treated so you’re not missing spots or hitting the same one twice.
• Moisturize and avoid sun after each session: reapply SPF 50+ for two weeks post-treatment, and hold off on exfoliating for at least 5 days.
• Don’t stop early: full results (up to 100% reduction) depend on completing the whole course, plus occasional monthly touch-ups afterward for any regrowth.

Must Read Before Doing Laser Hair Removal

Laser isn’t right for every situation:

• Skin tones outside the approved range: it’s only safe for Fitzpatrick skin types I–IV, so it’s not an option for medium-to-deep skin tones (types V–VI), since the laser can’t reliably distinguish between melanin in the skin versus the hair follicle at that end of the spectrum. The device has a built-in sensor that won’t even unlock on skin tones marked “Not Safe” on their chart.
• Blonde, white, red, or gray hair: the laser needs melanin in the hair shaft to work, so it simply won’t respond to light-pigmented hair.
• Anyone under 18: not approved for use on minors, by themselves or by someone else.
• Pregnant or breastfeeding: explicitly listed as a do-not-use condition.
• Eyes, eyebrows, or eyelashes: risk of permanent eye injury — never go near this area.
• Ears, nipples, genitals, or anus: too sensitive, too pigmented, and too hair-dense for safe use.
• Men’s beard area (face, jaw, neck): hair density there is too high for the device to treat safely.
• Skin with tattoos, moles, birthmarks, freckles, or recent sun exposure: the extra pigmentation confuses the laser’s targeting.
• Damaged or compromised skin: open wounds, cold sores, sunburns, or skin still healing (6–8 weeks) after a peel or resurfacing treatment.
• Anyone on Accutane/isotretinoin or other photosensitizing medications.

How I Use My TRIA Laser

Firstly, I made sure to protect my skin and not tan the weeks leading up to hair removal, which is something I already do but it also helps the device to work best. I shave the area (not wax or pluck!) because the laser needs that follicle still sitting there under the skin to actually target it. I start my session by cleansing the area and patting it completely dry. Then I apply Tria’s Phytogel so I can stomach the sting from the highest setting. I’ve tried both with and without it and I wouldn’t say it makes a real difference but I’ll take anything. I haven’t tackled the bikini area yet because I would most definitely need some heavy duty numbing cream.

I have to hold the bottom of the device against my skin so the little sensor can read my skin tone and make sure it’s safe to use there. It doesn’t work otherwise for safety. I used to start on a lower setting, like a 2 or 3, especially for my upper lip stache, but now I go straight for the 5. NGL, in the beginning it was a very uncomfortable, painful sensation, especially in the tender armpit area, but my skin has gotten more used to it. I try to do yoga stretches so the pain of the stretch distracts me from the Tria. This takes a solid half hour chunk of my time so I multitask by getting a red light therapy session in too. In the winter I’ll probably do it while in my infrared sauna.

Don’t even get me started on the face! I prefer using the highest setting on my armpits and legs since it’s the most effective – no pain no gain right. On my face I can only handle level 2 or 3 at most. This is useful for those random chin hairs too. One thing to keep in mind is sometimes you’ll feel pain and sometimes you won’t. Generally speaking, the pain means Tria is killing off the follicle. So pain equals good and the device is doing its job. If you don’t feel pain it’s likely that there’s no hair there to kill off anymore.

I press the window flat against my skin, wait for the beep and flash, then slide over just slightly so the next pulse overlaps the last one a little. I basically work my way across the area in sections so I’m not missing spots or accidentally doubling up on the same patch. You can even use white eyeliner to draw overlapping circles to help guide you so you don’t miss any spots.

I try to do my armpits, legs and arms during each session and I reach around 1,500 pulses, more if I’m also fitting in my lip mustache and lower back. The device doesn’t last the full session and needs a recharge in the middle. It can be long and tedious, but thankfully the Tria has a comfortable handle with good grip and isn’t too heavy. I also make a note on my iPhone calendar so I remember when I’m due for the next session every 2 weeks, because I’d totally forget otherwise.

My Results (Progress Diary)

I was honestly surprised at how well my hair responded to at home laser and I’m super excited this has been working because I was always skeptical. 70% hair reduction after just two sessions at home sounded too good to be true. If only I could make my dark spots go away this fast! I can tell the difference each session has made because my hair normally grows back SO fast and in a few weeks I’d be a bushy forest all over. No one else in my family has as much hair as I do.

First session results: Jotting down notes of changes I noticed. I definitely noticed my hair on my legs and pits grew back a little slower though the hair looked exactly the same. It usually grows back so fast in those areas and I’m normally shaving stubble every few days but it took about a week for stubble to start showing again. I would say I saw a solid 30%-40% hair reduction after the first session and hair grew back scattered

Second session results: My hair regrew pretty slowly again with some patches not even growing back yippee! I saw about 60% hair reduction after the second session and hair grew back scattered and thinner.

Third session results: Can’t tell you how amazing it is that the hair is growing back super slowly or not at all now. I have a lot less anxiety over needing to shave again, which I didn’t realize was such a constant normal part of my life. Girlhood yay. Bookmark this post to check back on my progress diary.

What I’ve learned:

• Hair grows back in cycles and not every hair is in the same cycle, so one session you may be effectively targeted certain hairs and not others. That’s why some pulses come with no pain.
• More sessions within the timeframe does not equal more results. Again, because of the hair cycle. And do not skip sessions either.
• Sessions will be hard to stick to if you don’t do something to alleviate the pain, whether it’s gel, distracting yourself like I do, or numbing cream.

Quick FAQ

Is IPL the same as laser? No. IPL scatters a broad spectrum of light, much of which never effectively reaches the follicle. Laser uses one precise wavelength (810nm for Tria 4X) tuned specifically to be absorbed by melanin in the hair.

Is at-home laser actually cheaper than the alternatives? Yes, over time — it’s a one-time $599.99 versus $2,000–$5,000 for a comparable in-clinic laser course, or thousands more over a lifetime of shaving or waxing that never produces permanent results.

How long until I see a difference? The clinical study shows up to 61% reduction after just 1 treatment and up to 75% after 2 — you don’t have to wait until treatment 8 to notice a change.

Will this help with razor bumps and strawberry legs specifically? Because it targets the follicle instead of just the surface hair, it addresses the actual cause rather than just the symptom, which is different from anything shaving or waxing can do.
