Can blemishes temporarily become darker after laser toning?

I am looking into laser toning to improve my skin tone and manage blemishes. However, while reading reviews, I saw a few posts stating that existing blemishes may appear slightly darker immediately after the procedure.

I’ve heard people describe it as a process where pigmentation rises to the surface, so I’m curious if anyone has actually experienced that. If it does occur, I’d like to know how many days it usually lasts and whether it naturally fades over time.

I have never had a laser treatment before, so I am concerned about even the smallest details. I am wondering if it is okay to apply makeup immediately after the procedure, and how much attention I should pay to sun protection. I would like to hear from those who have experience with laser toning.
