I'm looking into this because of acne scars, but there are so many types.

As I have been looking at my skin up close more often recently
I realized that my acne marks are more visible than I thought.
I usually try not to pay much attention to it, but
When viewed under the light, there is a mixture of red marks and areas that look like pigmentation on the cheek.
Even with makeup, it didn't look completely clean.
So, I am writing to inquire about lasers because I would like to take this opportunity to get a proper consultation.
My biggest concern is that there are too many types of lasers.
If you search, there are really various names, ranging from toning to Fraxel-type lasers and vascular lasers.
It seems that even for the same laser, the explanation varies slightly from hospital to hospital.
My skin isn't particularly thick or resilient, and
I used a new cosmetic product incorrectly in the past, and
My skin has been sensitive before, so I don't necessarily want to undergo a strong procedure.
What I want is not for my skin to change completely all at once, but...
It's just enough to slightly even out the existing marks and skin tone.
I am especially curious if the red marks and the brown marks are managed in the same way.
If the type is different, please check my skin condition during the consultation.
I also want to check which parts need to be managed first.
