Is there a difference in cost for melasma skin boosters?

My skin is naturally thin and lacks moisture, so my face looks lifeless and dull all over, which really bothers me.

I am posting this question because I would like to add moisture to my face and significantly boost its elasticity through the Melasma Skin Booster treatment, a periodic nutritional injection therapy at Maypure, and I want to check the total budget I should set for the treatment, considering whether I receive a manual injection or use an injector machine like Hi-Cooks, on a per-session basis.

I heard that getting the injection with a machine reduces drug loss and pain, so I'm wondering if there is a significant difference in cost.

If there are any experienced users of injection care, it would be very helpful if you could share roughly how many sessions you received, the methods used, and the cost range involved. I would like recommendations for melasma skin boosters that fit my budget, and please let me know if there is truly minimal drug loss when using mechanical skin boosters.
