Was referred by a friend who had great results. I had a ton of dark freckles on my back that I wanted to get rid of. When I went in, Cindy did not take much time briefing me of the procedure and began immediately. It was really painful so I had to stop her and ask for numbing cream. Do yourself a favor and ask for the cream beforehand!! I'm Not sensitive to pain but this hurts pretty bad. Anyways after my treatment my back looked terrible, red and swollen. It eventually scarred up and began to heal. It took about 10 months to completely heal, I'm not joking. My friend said his took the same amount of time. While the treatment did completely removed all freckles it has replaced many of them with white spots where the freckle used to be... Not what I had hoped for. I had tried photofacials in the past which definitely do not have the same power that this laser has but in my case my results were not what I was hoping for. My dermatologist said that the scarring would happen but I had heard such great things about sonic skincare and my friend was a testament to that. I may be a rare exception for this happening and I'm hoping there is something I can do to minimize the white spots.
