I am curious about the effectiveness of the blemish treatment.

For those who have received blemish treatment, how were the results?
I am familiar with treatments for melasma, but treatments for blemishes are a bit confusing. I don't think I've ever actually received a treatment or even consulted about one.
I did hear the information, but it wasn't very detailed, and I didn't feel there were any particular advantages.
How much care does this procedure actually provide? I'm curious if it includes treatment for melasma, or if it just really makes the skin a little clearer.
I was wondering if getting this blemish treatment would be a much better choice than getting a melasma treatment, since it also provides melasma care.
I am curious about the effects and reviews from those who have received it. I am also wondering which place is better in terms of price.
I would appreciate your guidance.
