Tria Laser Hair Removal FAQs

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

While the hair removal technology is the same across both devices, the Tria Laser Precision is designed specifically for quick treatments in small areas, such as the underarms. We highly recommend the Tria Laser 4X if you are considering treating larger body areas, such as the leg. Tria Laser 4X is our most advanced device with additional features to guide you through each extended treatment.

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

The Tria Laser Precision is intended for people with light to medium skin tones in the area they wish to treat. Darker skin tones can absorb too much laser light, which may injure the skin. The built-in skin sensor will determine if at-home laser hair removal is suitable for your skin tone.
Note: skin tone in one area can be darker or lighter than skin tone in another area, so it is critical to use the built-in skin sensor in the area you wish to treat.

Tria Team: Customer Care

The Hair Removal Laser Precision is designed to work on naturally light brown to black body hair in the area they wish to treat. Because the Hair Removal Laser Precision 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

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.

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.

It is normal for the cooling fan to turn on and emit warm air through the bottom vent as soon as you unlock your device. You should continue treatment while this is happening and do not need to wait for it to turn off before treating the next area.

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 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 Precision:

1. Unplug the Tria Hair Removal Laser Precision from the battery charger. It will not turn operate while plugged in.

2. Hold the device and press the power button to turn it on. The top and bottom indicator lights will turn green, indicating that the device is locked.

3. The skin sensor is in the device tip. Place the tip gently against 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 wish to treat, the Tria Hair Removal Laser Precision will emit a series of "da da da" and the indicator lights will change to Low treatment level if using for the first time OR the most recent treatment level. If the top and bottom indicator lights remain green and you do not hear a series of beeps, then the Tria Hair Removal Laser Precision 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 also 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. Make sure that the top and bottom indicator lights are on before you place the tip against the area you wish to treat, ensuring that you do not push the tip into the skin.

Note: When the Hair Removal Laser Precision is not in use for 30 seconds, the device will automatically turn off.
