✔️ Where should I start with combination skin?

Hello~~! My skin is a bit of a mixed bag ㅠㅠ...

Some days my skin gets really shiny because of oil, while other areas are dry and tight, and even get flaky skin... (It's a total mess...)

Over time, the nose and forehead become shiny, making the pores look even more prominent.
The cheeks and chin area are actually dry and sensitive, so their condition deteriorates quickly with even the slightest irritation..!

If I control the oil, it becomes dry, and if I apply moisturizer, it gets greasy...

When I look into dermatology procedures, there are so many types that it makes me even more conflicted.
I'm not sure if I should focus on sebum control or if I should prioritize improving my skin barrier and moisture balance first...!

For those with combination skin, which treatment were you most satisfied with?
I wonder if the ones that help with oil control, like Potenza or Skin Botox, were better....
Or would a treatment that balances the overall condition, like a skin booster, have been a better fit?

For someone with combination skin like me, what criteria should I use to choose a treatment?
