Will 8 days be enough time to recover after a rhinoplasty and chin augmentation? (Photo)

Maybe but over the internet we can give ONLY generalized recommendations not specific to your exact case... In my opinion for 3 weeks is needed for 80%+ recovery. 

There is usually more bruising associated with the rhinoplasty than a chin implant. It is possible to return to work 8 days after the procedures, however you will most likely have some degree of residual bruising and swelling. In our practice, we tell patients to expect approximate 10-14 days of some degree of swelling and bruising which is variable among patients.

Each physician have different guidelines regarding post operative care. Typically, light activity can resume 5 to 7 post surgery. Bruising and most swelling generally resolve itself in the first two weeks. Residual swelling that can take 6 to 12 months to resolve but not noticable to the general public. Consult with your surgeon regarding your case as he or she will know the scope of surgery and the specifics about you.
