How long does Jubelook last for sunken cheeks in people in their 40s?

Now that I'm in my early 40s, I'm worried about melasma, but lately I'm more concerned about the sunken look on my cheeks below my cheekbones.

It’s not like I’ve lost weight, but by the afternoon, my face looks haggard and my makeup looks patchy on my cheeks.

I am still hesitant about methods like fillers that fill in immediately, so I am looking into the Juvelook procedure, which helps stimulate collagen production to gradually build up volume.

I looked it up and found that it is common to receive it with a few sessions spaced apart rather than just once, and that it takes a little time for the effects to show.

I'm also managing my melasma, so I'm worried about how to schedule my time.

① I'm curious about how long the Jube Look usually lasts based on cheek hollowing.

② I would like to know how many sessions are typically spaced apart when receiving it for the first time.

③ Is it okay to combine melasma laser treatment and Juvelook treatment during the same period?

I am asking because I would like to know in advance before the consultation.
