(Concern) Will old melasma reappear after laser toning?

I am currently in my late 30s.

There is a dark spot about the size of a 50-won coin just above both cheekbones, so I always use concealer when going out to hide itㅠ

I've been interested in laser toning treatments ever since I was in my early twenties.

However, since it often disappears after receiving and then reappears, I am hesitant to receive it easily.

I want to hear advice from experienced people!
