What treatment is effective for bumpy acne scars on the cheeks?

I am concerned because when I look closely at the skin on my cheeks, the surface is not smooth and there are bumpy areas here and there.

I can see several small marks on the upper part of my cheek in the photo, but I'm not sure if it's just enlarged pores or if I've developed acne scars.

In particular, since the skin texture itself can look different even when covered with makeup, I am looking for ways to improve it.

I looked it up and found that there are treatments used to improve skin texture, such as Fraxel and Potenza. I am curious about the differences between them.

I would like to know if I need to receive the procedure multiple times even if the scar is not deep, and how long the redness or peeling lasts after the procedure.

In cases where small scars and enlarged pores are visible together, as shown in the photo, which procedure should I consider first? I would also like to inquire about the cost and recommended number of sessions.
