Do I need to do separate aftercare to maintain the effects of the acne treatment for a long time?

I'm considering getting an acne treatment, but I'm wondering if the procedure itself is the end of it, or if I also need to do aftercare.

I'm worried because I've heard that if you don't take care of your skin after getting an acne treatment, the breakouts can come back.

I also want to know what kind of daily care is needed to maintain the effects of acne treatments for a long time.

I'm curious if the cosmetics I use or my lifestyle habits have a significant impact, and I'd love to get some tips from those who have maintained their results for a long time after acne treatments by taking good care of their skin.

If anyone happens to know, let's share!
