Is the basics of whitening removing blemishes?

I had a mole removed when I was young, but whether it was because of the technology back then or because it was a large mole, a slight scar remains.

I'm worried about not being able to wash after removing the mole, but my biggest worry is that a scar might remain.

However, when it comes to whitening, removing blemishes should be the top priority, right?

I heard that urology clinics also remove moles these days.

You should be able to remove blemishes cleanly without scarring.

I want to give it a try, but I'm also worried.
