Does getting acne treatment definitely improve your skin?

Hello. My child, who is at the age where acne is at its peak, is stressed out because of their skin.

We no longer live in an era where acne is simply left alone like in the past, so let's look into acne treatments for children.

I have it, but in the past, when I went to the dermatologist, it was only clear while I was receiving treatment, but it would return to its original state once I stopped the procedures.

There used to be a lot of stories like that. Of course, that wouldn't be the case these days, right?

I would like to know what kind of procedure is performed for acne treatment, as a single session won't be enough, and I am curious about the recommended number of sessions and the cost.

For those of you who have received acne treatment, how satisfied were you?

I am looking for a suitable treatment for my child, so I am thinking carefully about it.
