What is the typical treatment cycle and procedure time for acne?

Hello~ Lately, as the weather has gotten drier, I'm worried because red acne keeps popping up on my chin and cheeks. One pimple disappears, and another pops up in a different spot. I couldn't resist squeezing them with my hands, which left marks that even makeup can't cover up.

So this time, I'm looking into getting proper acne treatment, but since it's my first time, I have a lot of questions.

First, I’m curious about the typical treatment intervals for acne, specifically how often you schedule them, and how long each session takes. I’d like to know if I can go after work while I’m employed.

Also, I would appreciate it if you could let me know if it is okay to apply makeup immediately after the acne treatment is finished, and how long the redness lasts if any remains.

If anyone has received acne treatment, it would be a huge help if you could share your experience on how many sessions it took to feel the acne subsiding!
