How was the blemish-reducing effect of Clarity?

Hello. Since my skin is fair, I tend to get freckles easily. About two years ago, I had them completely removed using a scab removal laser. However, after the summer passed, they definitely became much darker again. While looking into scab removal lasers, I found out that May Pure uses the Clarity blemish laser, so I am posting this to hear some reviews. For those who have received the Clarity blemish treatment, could you tell me how the results were? I am also curious whether you saw results after just one session or if you required multiple treatments.

Also, since my skin is quite sensitive, I'm a bit worried. Surely no one has had their skin barrier compromised after getting the Clarity blemish treatment, right?
