There seems to be quite a bit of variation in a person's tendency to bruise and the severity of bruising with filler injections. Avoiding blood-thinning agents (e.g. NSAIDS, aspirin, vitamin E, omega-3 fatty acids, garlic) would be a good idea 1-2 weeks prior to the procedure. Good technique with attention to minimizing tissue trauma can help. In spite of all these measures, bruising can still occur and last up to 2 weeks, sometimes even longer. Filler injections 4 days prior to an event or trip would be cutting it close; I would suggest a period of 10 days.
Good luck.
