When can I start washing my face as usual after the procedure?

I have some questions that arose while researching dermatological procedures. Although it may vary depending on the type of treatment, it seems that facial cleansing methods often change from usual after the procedure. I am confused because some people tell me to just wash with water on the day of treatment, while others say it is fine as long as I do not irritate the skin. In particular, I would like to know when I can use cleansing foam and how careful I should be about rubbing my face while washing. Since my skin tends to be sensitive, I am more concerned about aftercare; I am curious to know how many days those who have actually had the procedure took precautions. I have heard that the results can vary depending on the care method, so I would like to know this in advance.
