Even though I don't have that much fat on my face, I got Accu injection to get a slight difference even by 1cm (cheeks + double chin) I started seeing the effect from the 2nd week and the maximum effect was seen for a month . Now that the weight has been sorted out, my friends ask me if I have lost weight. People with a lot of fat on their face seem to see the effect better with Accu injection. I was hit once.
