How many times is Larafil usually recommended?

I am extremely stressed every time I look in the mirror because of the pigmentation that has been creeping up under my eyes and on my cheekbones.

I feel that laser toning alone has its limitations, so I am seriously considering combining it with Lara Peel, which is said to provide synergy for pigmentation treatment.

However, I have heard that this type of ampoule treatment is not effective with just one session and requires consistent treatment over several times. Does anyone know approximately how many sessions the clinic recommends for melasma Lara Peel, and what the intervals should be? Since cost is a significant factor, I would like to create an overall plan in advance before starting Lara Peel.
