I would consider these factors before deciding on doing skinboosters and justifying its cost:
1. Doctor experience. Does the doctor provide a full consult and detailed analysis of your problem? Are other solutions offered for your concern that may be more cost friendly? Majority of my patients who ask for skin boosters usually find that I offer something a more comprehensive or targeted solution.
2. Quantity and brand. Good raw materials are important to get good results. High quality hyaluronic acid has multiple benefits for the skin. A large surface area that requires treatment may then need more product which will add to the cost.
3. Skill and expertise. Skinboosters should be done with a manual technique for best results and less side effects. This is more time consuming and slightly more technically challenging to perform. Good materials would be wasted if not done with a freehand technique, as most of it would not be placed in the correct layer.
Hope this helps!
