Questions about improving skin elasticity and firmness after minor procedures

Hello! I'm going to Seoul soon and I'm planning to have a small cosmetic procedure at a medical clinic and then come back. I'm thinking about how long it will take to heal after the procedure. I'm not sure how it will work during a flight.

Have any of you been in a similar situation? What products should I bring to help with the pain from the surgery? And are there any things to keep in mind when flying? I'd really like to know what kind of skin care products will help me with this process. Please share your good advice and experiences!
