It actually works! I already see a lot less hair growing and my ingrowns are basically gone!”

– Amna N.

Here's why customers like Amna love the 4x




Effective like no other

Our advanced hair removal laser technology safely delivers up to 4x more hair eliminating energy than any other at-home hair removal device. The device targets each hair follicle with concentrated energy, disabling it faster and more effectively, to reveal your smooth, soft skin.




than IPL

It’s laser, not IPL

IPL-based devices use broad spectrum light, which doesn’t penetrate as close to the hair follicle as laser does. This means less control in the application, and longer treatment times. Our 4X uses laser, which is highly concentrated light. These focused beams quickly target and disable the hair follicle without impacting the surrounding skin, ensuring long-lasting results in fewer sessions.

“The Tria isn’t cheap… but over the years, I probably spent at least that much, and probably much more, on over-the-counter treatments that didn’t work. And the confidence boost alone makes this purchase worth every single penny.”

According to the dermatologist-led study**, an average hair reduction of up to 60% was noticed among all subjects after 1 month of treatment.

These results were maintained even a year following the treatment.

In the same study, 100% of the subjects were satisfied with the results from the HRL 4X, including 38% who were extremely satisfied, at the 12-month mark after their last treatment.

In another survey, 77% of our users—3 out of 4—responded that they are likely to recommend the device to loved ones.

Our customers love the user
experience of HRL 4X.

Kickstart your hair-free future with 3 simple steps.

Tria Skincare

Step 1: Prep
Clean the area you want to treat. Shave it. Towel dry.

Tria Skincare

Step 2: Get set
Choose the treatment level you’re comfortable with—the HRL 4X offers 5 settings. Pro tip for beginners: always begin at the lowest level, and work your way up.

For each use, you will need to unlock it. Position the skin sensor on the device close to the area you wish to treat. If the device can be safely used on your skin color, you will hear two beeps. The device is now unlocked!

Tria Skincare

Step 3: Go
Lift and place the device on your skin to zap the hair follicles. It is important to overlap the treatment area to ensure all follicles are being treated. Continue doing so until the entire treatment area has been covered. If the device beeps and emits white light, it means your hair follicles are getting targeted and zapped!

For best results, treat the desired body part every two weeks, and continue doing so as necessary.

Precise, Powerful, Proven.

The How Behind HRL4X.

Targets: The HRL 4X laser effectively targets the pigment in the hair, without touching the surrounding skin. Your hair pigment, called melanin, is what gives your hair its unique color. Every hair follicle—a tube-shaped sac—contains melanin. This hair follicle is also responsible for hair growth.

Treats: Once the device identifies the hair melanin (differentiating it from the melanin in the skin by color), it sends highly-concentrated light through it. The light is converted into heat, which disables the hair follicle.

Disables: The hair from the disabled follicle falls out, leaving behind soft, smooth skin.

Maintains: Over time, the laser effectively disables the hair follicle’s ability to grow back hair.

Take the test.

Laser technology is not
recommended for certain skin

No pain, no gain. But how painful is it?

In the clinical study, almost all users reported mild to moderate pain or discomfort during their first treatment, with a reduction in sensitivity reported in their later treatments. You may feel warmth, burning, tingling or itching; some users described feeling the same level of discomfort as when a rubber band snaps against the skin. If the pain is too intense or persists after a treatment, stop using the Tria Laser 4X and check with your doctor before using it again.

What customers are saying

“It works! Most of my
trouble areas are gone!

I have had this device for about 3 weeks. I use it almost daily and now most of my trouble areas are gone! I have had facial chin hair for about 15 years, and this is the first time I have ever noticed this big of a difference. I then tried my armpits, which are nearly gone. I plan to wait several weeks to make sure. But for now, I love it and would highly recommend.”

– Christine H.

“Very easy to use.

I am not tech savvy but it took me only a couple of minutes to figure it out.”

– Desiree Bedolla13

While both devices feature Tria's proprietary, FDA-cleared diode laser technology to deliver permanent results, the ideal device for you should be determined by where and how you would like to treat. Tria Laser 4X is our most advanced device with additional features to help guide you through your treatments. You can treat multiple body parts with faster treatment times and an upgraded battery pack. Tria Laser Precision is our lightest and slimmest device, designed to treat your small, sensitive areas, such as underarms and bikini area. It's ideal for quick treatments in the small, targeted areas that you shave or wax. Check out our product comparison chart to find the right device for you.

Yes, the Tria Hair Removal Laser can be used on women's facial hair (cheek line downward). Darker, coarser facial hair is likely to show more pronounced reduction than lighter and finer hair known as “peach fuzz” on the upper lip and side of the face. Men should not use it on their face due to the density of facial hair.

Tria Team: Customer Care

Each battery charge on the Tria Laser 4X lasts about 30 minutes. This battery life allows users to stay focused and conscious of overlapping during treatment. A rule of thumb is that a single battery charge is enough to treat a larger area, such as the lower leg, or multiple small areas, such as the upper lip and underarms.

Tria Team: Customer Care

We recommend that you prepare your skin before each Tria Hair Removal Laser 4X treatment for best results.

  • Cleanse the treatment area thoroughly, removing all cosmetics, lotions, and creams from the area you wish to treat. (This will allow the laser treatment to easily penetrate the skin.)
  • Shave the treatment area thoroughly using a new razor. This allows the laser treatment to be most effective because the laser works on the hair inside the follicle, under the surface of the skin.
  • Wipe your skin with a cool, damp cloth to remove any shaving cream or soap, and then dry the area well.

Please note: Waxing and plucking are not advisable any time between treatments because both remove hair from the follicle. The hair inside the follicle needs to be present for the Hair Removal Laser Precision treatments to be effective.

Tria Team: Customer Care

We recommend treating every 2 weeks for best results. This treatment protocol is optimal to target the hair follicle at the proper stage of its growth cycle. For permanent results, treat the area once every 2 weeks until desired result has been reached.

Wheeland, MD, FACP, Lasers in Surgery and Medicine, 2007. Individual results may vary.

Tria Team: Customer Care

The Hair Removal Laser 4X is designed to work on naturally light brown to black body hair. Because the Hair Removal Laser 4X works with the dark pigment in the hair, lighter hair colors such as white, blond, red, or gray will not absorb enough of the laser's energy to disable the hair follicle.

Note: hair color in one area can be darker or lighter than hair color in another area, so check the hair in the area you wish treat.

Tria Team: Customer Care

After each treatment:

  • The skin may experience mild redness that typically dissipates within 24 hours.
  • Hair that was effectively treated begins to fall out. Hair that regrows may be finer and lighter. Continue your regular treatments.

After 3 months of treatment:

  • With each treatment, additional follicles will be treated. Hair follicles that have been deactivated by the Tria Hair Removal Laser 4X will no longer grow hair. Continue to use the Tria Laser until you achieve your desired results.

When used as directed. Results will vary based on skin tone, hair color, and other factors. Some users may require additional treatments to achieve the desired results and may opt for occasional touch-ups using other hair removal methods.

Here's how to unlock the Tria Hair Removal Laser 4X:

1. Unplug the Tria Hair Removal Laser 4X from the battery charger.

2. Hold the device and press the power button to turn it on. The display window will show that it is locked.

3. The red light on the bottom of the device is the skin sensor. Hold it on the area you wish to treat to check your skin tone. The skin sensor will automatically sense and check your skin.

If it's suited for your skin tone in the area you want to treat, the Tria Hair Removal Laser 4X will emit a ready tone and the lock indicator in the display window will disappear.

If the lock is still visible on the display window and you do not hear a series of beeps, then the Tria Hair Removal Laser 4X may not be suitable for your skin tone in that area. Verify that your skin tone in the area you wish to treat matches the intended tone on the Skin Tone + Hair Color Chart on page 2 of the Instructions for Use. You may be using the skin sensor incorrectly and need to try again. To try again, lift the skin sensor from your skin and follow the previous two steps. If you are still unable to unlock the Tria Hair Removal Laser 4X, contact Customer Care at 1-877-321-8742.

Note: When the Tria Hair Removal Laser 4X is not in use for approximately 3 minutes, the device will automatically turn off.

Tria Team: Customer Care

No. The Tria Hair Removal Laser 4X is designed for personal use only. Sharing the device is not recommended for personal hygiene reasons.

Tria Team: Customer Care

No. Do not use the Hair Removal Laser 4X on genitals. These areas may have more sensitive skin, a darker skin tone and/or a greater hair density. Using the Hair Removal Laser 4X in these areas may cause serious skin injury. You may use the Hair Removal Laser 4X on your bikini line, which is the pubic hair visible beyond the boundaries of a swimsuit.

The Tria Laser 4X should not be used by or on anyone under the age of 18. The use of the Hair Removal Laser 4X on or by children has not been studied and could result in serious injury.

Tria Team: Customer Care

No. Do not use Tria Laser 4X on parts of your skin that are darker than your usual skin tone: tattoos, dark brown or black spots (such as large freckles, birthmarks or moles). Dark skin may absorb too much laser light, which can injure the skin.
