the required time by plastic surgery since the original plan until the final aesthetic result

There is no medical reason to determine the best time to undergo the plastic surgery. The best moment may depend on the type of surgical procedure, the recovery time, the lifestyle, working hours and on your social commitments.
You should consider these factors:
Depending on the plastic surgeon, you must wait several weeks to get a consultation and other weeks or months to perform your plastic surgery.
Call the surgeon's office and ask about the surgeon's surgical timetable. If he isn't available on the date you want, call to the next surgeon on your list - but if he is the surgeon that you want, then try to adjust your time with the surgeon's time or ask to be placed on the waiting list for cancellations.
If you haven't time to make your plastic surgery, how you will have time to recover from your plastic surgery? Your body will need a time to heal quietly. Otherwise, you may inadvertently cause complications and delay the recovery.
Prefer to make your plastic surgery when you have less social demand, less work or during your holidays. If you can't deal with the time required in recovery, then postpone your decision until you have time for your plastic surgery.
