How often is exfoliation recommended?

Lately, my skin condition isn't what it used to be, so I've been quite worried. I'm particularly bothered by my makeup looking patchy and dead skin cells constantly being visible. Naturally, this has led me to become interested in professional exfoliation treatments at a dermatologist's office. I've tried managing it at home with scrubs and peeling products, but they only seemed to irritate my skin and made it feel even drier, so I'm considering whether I should get proper exfoliation care.

After doing some research, I found that there is a really wide variety of exfoliation treatments offered at dermatology clinics. With methods like aqua peels, chemical peels, and lasers, and knowing that each has different effects and levels of irritation, I am feeling quite confused. Since I have sensitive skin, I am particularly worried that getting the wrong treatment could worsen my breakouts. I am interested in treatments that not only remove dead skin cells but also manage pores and sebum, but I don't know how to choose the method that is right for my skin.

And what I am most curious about is the recommended frequency. I think the cost and time plan will vary depending on whether a single session is effective or if consistent treatment is necessary. I understand that it usually depends on skin condition, but I would like to know the average recommended frequency or cycle. I am most concerned because I have heard that doing it too often can actually weaken the skin barrier.

Another concern is post-procedure care. I heard that moisturizing and sun protection are important after receiving exfoliation at the dermatology clinic, and I am curious about how much attention I actually need to pay. I am also worried that my skin might become more sensitive than usual, so I am concerned about whether it will interfere with my daily life.

The cost is also a factor that cannot be ignored, so it might be a burden if I have to receive treatments multiple times. However, I am willing to invest if my skin definitely improves, but I would also like to hear from those who have actually experienced it about the level of satisfaction.

To summarize, I am really curious to know what criteria those of you with sensitive skin like mine, who struggle with dead skin cell issues, used to decide on dermatological exfoliation treatments, and how you determined the recommended frequency that suits you. I am having trouble making a decision because I am afraid that choosing the wrong option might just make my skin even worse.
