I received PicoSure laser treatment.

This kind of skin care laser is my first time trying it after receiving a few sessions of Fraxel in the past.

Is it worth doing if I need to receive it ten times to see any effect? Since it's my first time, I only received it once, but there's no redness on my face or any change at allㅠㅠ

I want to get rid of dark spots and acne scarsㅠ
