Photo notice) Please tell me how to get rid of back acne ㅠ

Back acne is really stressful in many ways!

Should I go to the dermatologist for treatment?

Actually, I had a peeling treatment at a skincare clinic once, but it was just for a short time, and then it came back right away. I think I need some basic treatment.

I paid 300,000 won for a peel treatment, but I wasn't satisfied, so I'm really upset about it.

So, how much would the treatment cost if I go to the dermatologist? Also, since acne cases vary depending on the person, I'm worried about that too. I'm concerned about spending money and time at a skincare clinic only to end up not getting proper treatment...

Has anyone tried treating back acne?

This is my back when I received a peeling treatment at a skincare clinic.

30,000 won for Filling 1, wow wow wow

I'm posting a question just in case dermatology is like this too.
