Personal Legato 2 Review

I have some visible pores next to my nose, and I also have acne scars. And my overall skin didn't feel smooth, and it felt blotchy and bumpy because of the scars, so I got Legato 2 treatment for my entire face. After getting it done, my skin regenerated for about 1-2 weeks and I could definitely feel it getting a lot better. But I think one treatment wasn't enough. After about a month, my skin looked like my original skin again lol.
  But I think my skin will improve a lot if I keep getting it done, so I'm thinking of getting it done additionally. But I'm worried that this will only have a big effect the first time and that there won't be much of a change in the 2nd and 3rd treatmentsㅠ The price is not cheap either..
 
Is there anyone who has kept getting Legato 2?
