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

8 days to recover from rhinoplasty is enough in the sense that you'll be physically able to participate in many work related duties and some exercise.  However, if you are a VERY  private person you may find there are some signs of your surgery (mostly swelling) that will linger and possible tip others off to your recent work.  That being said there's a good chance you will be presentable.  Best of luck.  You will likely be fine but, again, there should be some swelling remaining.Chase Lay, MDdouble board certified facial plastic surgeon

Recovery after a dual rhinoplasty and chin implant is gradual and can be broken down into stages. After the first week, you should be cleared to resume light daily routines, given that you are still avoiding strenuous physical activity and are allowing your body adequate time to rest. At 8 days post-op, you will likely still be noticeably swollen and bruised. However, if you feel comfortable enough at this point to return to work (given that you are not straining or over-working yourself), you should be able to do so. 

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.

This depends on what you mean by "recovery." After eight days you
should be feeling fine and able to do just about anything--the
exceptions being that you'll need to avoid strenuous work and being out
in the sun. You could still have some bruising at this point, and it's
likely there will be some swelling.
Arnica montana does help many patients. Take it as directed by your plastic surgeon and follow any other advice he or she has about speedy healing. Initial
healing from a chin implant is pretty quick for most people.
Rhinoplasty recovery takes a little longer. Makeup may cover any
leftover bruising, but my guess is that people who know you well may be
able to tell something is different. Consult your plastic surgeon to
learn more specifics.

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.
