The Tria laser is a device cleared by the FDA for home use 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 five adjustable settings from low to high. The highest setting (five) uses the most heat and will give better hair reducing 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 built-in skin sensor that will test your skin tone and determine if it's light enough. Only if your skin passes 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.
What are Some Changes to this New Model?
- Built-in skin sensor. On the previous models there was a separate sensor to check skin tone and used to unlock the unit. Now it's automatic.
- Digital display. The window displays the five power settings, battery charge, skin sensor indicator, and if the device is locked or unlocked.
- New design. Sleeker with a slim handle and new angled tip to make the device easier to handle and be able to see where you're placing the laser with more accuracy.
- Faster treatments, treatment time and charges. Depending on the level used there's up to a 50% faster treatment time with each charge. The battery recharge is now 30% faster. And also with each charge there's 20% more treatment time.
- Two treatment methods. The new Tria Laser can be applied on the skin like the previous model by placing and lifting it. An alternate way is by gliding the laser tip.
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. Bi-weekly treatments for at least 6 months (12 treatments) are recommended.
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.
