Isolaz and other concerns

Hello,
I’m 32 yrs old, latina with light color skin. I’ve always had very thick hair on my legs and underarms. In my teenage years I started to grow hair on my chin and upper lip.

I started permanent hair removal on my chin and upper lip only with Isolaz/Aesthera about 7 weeks ago. I have had a total of 3 sessions. My doctor told me I only needed about 5 or 6 sessions to see full results. However I have not noticed any change. He tells me to be patient but thats easier said than done, especially because I was told not to tweeze the hair during the procedure.

Should I be seeing some kind of results by now?

Also I wanted to know (since I cannot pull them with tweezers) how will shaving affect the Isolaz procedure?

And last but definitely not least what are your thoughts on Isolaz? I’ve read through some of the posts on this forum and there is very little mention of it.

Thx
