Will getting an acne treatment be effective even if I only get it once? Haha

I'm seriously so stressed out because of my skin these days. Acne keeps popping up repeatedly, especially on my chin and cheeks, so I just sigh every time I look in the mirror. As soon as one goes away, another one appears in a different spot, leaving red marks that make my skin look messy overall. So, I'm considering getting a proper acne treatment this time.

However, what I am most curious about is whether there is a noticeable change even after just one acne treatment!! Hospitals usually say that you need to get it done multiple times, but honestly, it seems like everyone says the same thing during consultations, so I was actually more curious about real reviews lol. I really want to know if the redness and inflammation subside or if the skin looks a bit clearer with just one treatment.

I am concerned about whether it is okay to get an acne treatment, especially before an important appointment. I would be so upset if I ended up getting it only to have the redness get worse. I am also wondering if acne treatments like extractions or anti-inflammatory injections tend to show immediate results.

For those of you who have actually received acne treatment, please share your honest reviews of your first session!! I am really curious to know if you were satisfied after just one treatment~~
