(Question) Which skin booster is good for beginners?

I have never had a skin booster treatment before, but I am worried because my skin is severely dry from within due to the dry weather during the changing seasons. Since I have combination and sensitive skin, I am concerned about whether a skin booster would be suitable. As a first-timer, what types of treatments are suitable and not too overwhelming? Is it okay for combination and sensitive skin? Combinations of two or three treatments are also fine, so please share reviews from those who have actually tried them. Also, how much pain is involved? Is it okay if I apply anesthetic cream? What is the approximate price? I am curious.
