Tria Laser Basics

Tria laser is a device cleared by the FDA for home use that can be used on the legs, bikini line, underarms, feet, arms, hands, chest, and back. It requires multiple treatments to have the best results.

How Does Tria Laser Work?

A diode laser uses beams of light heat on the follicles to disable them. It has 3 adjustable settings, low, medium and high. The highest setting uses the most heat, and will give better results.

Who Can Use It?

Those with light skin tones (white, ivory, beige and light brown) can safely use Tria. The system comes with a skin sensor that will test your skin tone and determine if it’s light enough to use. Only if your skin passes with a green light, will the laser unlock for use. Scarring, blistering and burning can result if it’s used on skin tones that are too dark.

Because this laser is targeting dark pigment, white, gray, blond or red hair will not benefit from using the system. Even if the hair is darkened with color, the hair follicle won’t absorb enough laser light to be effective.

Does Tria Laser Hurt?

That depends on a lot of factors, and everyone has their own tolerance to pain/discomfort. You might feel more pain if you have sensitive skin, or very dark or thick hair. Using the highest setting will also produce more heat, and of course, more likely to give you pain or discomfort. The first time using the laser is usually the most uncomfortable, and then subsides with further uses for most people.

How Effective Is It?

Hair grows in different stages: growing, resting and shedding. Because all of the hair isn’t on the same stage at any given time, multiple treatments are needed to get the hair in the growth phase, for the laser to be most effective. So 6-8 treatments are recommended, 2- 4 weeks apart.

Laser hair removal can lead to permanent hair reduction. Users of Tria laser reported “70% reduction in the amount of hair after just three treatments. Hair that did grow back was perceived to be finer and lighter,” according to the information packet provided by the company that makes Tria.
