The science behind Tria Hair Removal
Laser 4X

easy to use hrl

Precise, Powerful, Proven.

Tria Laser 4X features the same core diode laser technology preferred by dermatologists. While professional devices may offer higher peak power and/or greater speed of laser pulse, the Tria Laser 4X delivers excellent, permanent results in the comfort and privacy of your own home.

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.

All in your hands. Our 4X is one of the few home-use laser devices that is FDA-cleared; feel free to use it regularly. As an added precaution, the HRL 4X only activates if your skin passes the safety test.




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.

Tria’s advanced hair removal laser technology safely delivers over 3 times more hair-eliminating energy density (J/cm^2) than any other at-home hair removal devices. Our ultra high energy density, coupled with its precise laser wavelength selection, effectively targets the pigment in the hair follicle to permanently disable its ability to regrow hair. And, it’s so safe and effective, you’ll be amazed at what you can do all by yourself.

Tria Hair Removal Lasers are the only at-home hair removal devices featuring diode lasers, which disable the hair follicle by targeting the melanin at the root without damaging the surrounding skin.

The science behind Tria
SmoothBeauty™ Laser

adl science cirlce

The SmoothBeauty™ Laser sends targeted beams of light deep within the skin to stimulate collagen production the same way that professional laser treatments do.

science icon 1

Treats skin from deep within: SmoothBeauty™ Laser’s patented beams of light penetrate deep into the skin to disrupt the cells in microscopic zones.

science icon 2

Boosts your skin’s natural rejuvenation process: Your body’s healing mechanism immediately springs into action and produces collagen to heal these microscopic wounds.

science icon 3

Rebuilds collagen, reveals radiance: New collagen is rapidly produced, forming fresh, tighter skin to replace older, wrinkled skin. Regular use of the laser device ensures continuous stimulation of collagen, leading to more radiant, youthful skin over time.

Power only matched by safety

Power only matched by safety

SmoothBeauty™ Laser features medical-grade technology, but with reduced power and speed (450 microns penetration depth vs. the clinical standard of 650 microns), making it perfect for regular home use. It is FDA-cleared and safe to use on the entire face, for all skin types and tones.
