Inquiry about skin booster effects

Hello, I am an office worker who is concerned about melasma around my cheekbones and my overall dull complexion. I recently learned about a skin booster procedure that is said to be effective for improving melasma, so I would like to ask you a few questions.

​

What is the most effective skin booster ingredient (e.g., tranexamic acid, exosomes, etc.) for my melasma condition (light brown/dark spots)?

I am currently considering laser toning. What is the synergistic effect when combined with a skin booster?

I would like to know how long the embossing or bruising lasts after the procedure, and whether I can immediately resume daily activities (such as applying makeup).

How many treatment sessions usually do I need to see a noticeable change?

I will take your response into consideration when scheduling a consultation. Thank you.
