I bought a package of 5 for permanent hair removal on my upper lips and chins. Aftter akk five treatment, my facial hairs on my chin, and upper lips are still there. I reasoned with the technician because the result was no where to be found, I was given a partial refund.
The experience was painful and I had 3 zebra straps under my chin after my second treatment. It was due to the technician was using too high of the power, and subsequently burned a portion of my chin.
