The TRIA Laser Hair Removal System is the first and only FDA-cleared laser hair removal system available that uses the same trusted laser technology as the pros and provides the same lasting results - at home. In as few as eight simple treatments, you'll never have to shave or wax again. End of story. WHAT TO EXPECT What it feels like: The sensation is similar to the feeling of a warm rubber band being snapped against the skin. Does it hurt? Some people feel a moderate warming or prickling sensation and some feel no sensation at all. It's important to note that any sensation you may feel will lessen as the hair becomes finer. After 1 month: There will be no visible change to the hair or the appearance of the skin. Be patient - the results are worth the wait! After 2 months: Results. The hair will begin to lighten and become finer. After 3 months: Progressive results. You will begin to see a visible reduction in the amount of re-growth, especially in areas where hair growth tends to be dense, like the bikini line for women or the back and chest for men. After 8 months: Lasting results. Hair follicles that have been disabled by the TRIA System will not grow back. Simply continue to use the TRIA System until the skin is completely smooth and hair-free and then, you're done! How many treatments? Dark, coarse hair: Approximately 6-8 treatments. Brown, fine to medium hair: Approximately 8-12 treatments. The TRIA System is for people with light to medium skin tones and dark hair. Each system comes with a skin sensor so you can test your skin prior to treatment.
