Can Laughing and Smiling 2 Weeks After Rhinoplasty Effect the Final Results?

Smiling and laughing is a good thing!  don't be worries about changing the final result, you may have just stretched the area which is why you felt some pressure.
 

Smiling or laughing two weeks after rhinoplasty should not be a problem other than causing some discomfort from the stretching effect.

Smiling and laughing two to three weeks after your rhinoplasty certainly will not affect your results. Your nose will soften and improve slowly over the next several months, though now you should enjoy yourself and stop looking so closely.
Best of luck,

Smiling and laughing 2 weeks after a Rhinoplasty should not have any impact on the final result.  Anything that drmatically increases the blood flow to the face and nose however, should be avoided for the first month after a Rhinoplasty IMHO.

The goal after Rhinoplasty is to be smiling and laughing! You are so soon in the post operative phase that you will detect differences everyday of the recovery phase. As long as you do not cause any trauma to the nose you will heal just fine. Post rhinoplasty swelling is normal while most of the swelling will dissipate in the first three to four months you will still have about 10 to 20 percent swelling that will take an entire year to completely heal. Watch your salt intake, sun exposure and extreme exercise in the beginning and remember time is on your side and keep smiling! Best regards!
