How can I remove acne scars if they turn dark like moles?

I wonder if it's because I didn't take good care of the area where the acne appeared, or

I'm not sure if it's because of the UV rays since it's summer, but it left a scar-like mark, and now

Now it has turned into a slight dot and remains dark.

It seems like this is already irreversible.

I've tried applying regenerative ointment and using products that are said to be good for scars, but

It isn't getting better, so I'm planning to get it resolved at a dermatology clinic.

I'm wondering if I should treat this as a mole and have it removed with a laser, or if there is another method...

As for the dot, I don't think I should do it this season, so I'm putting it off for a while.

I was thinking of getting it done in the winter, but if not, I really want to get rid of it right away.

It covers up with makeup, but it bothers me otherwise.
