Can I see the effects of the blemish treatment after just one session?

I would like to receive treatment for blemishes caused by light pigmentation around my cheeks, but I am writing to inquire because deciding on multiple sessions from the start feels a bit overwhelming.

In my case, rather than having dark freckles spread widely, I just have small blemishes and some areas with uneven skin tone.

So, first, I would like to try it out to see if it suits my skin and to check the recovery process.

Can I see some results from the blemish treatment after just one session? Or is it generally correct to assess changes after a certain number of sessions? I would also like to know if the number of treatment sessions varies significantly depending on the depth or intensity of the pigmentation.

I would like to be guided on how many sessions I can realistically expect given my condition during the initial consultation.
