Only ever used soap and water — where do I start before a skin consult?

Lurked here for weeks. I'm 31, never owned a moisturiser in my life, and I'm going to Seoul in January mostly for work but want to book a skin consult while I'm there (some acne scarring, oily, big pores). I'm a bit worried I'll walk in and they'll hand me a 10-step routine I'll never follow. Is there anything I should start doing now so I'm not starting from zero, or just turn up as is and ask?
