Is it common putting tape on injection site after Restylane in tear trough.

I
have never heard of putting tape over a Restylane injection site, but
that doesn't mean it shouldn't be done, as long as your results are
good. Please call your practitioner if you feel uncomfortable. Best,
Dr. Emer

Thank you for sharing your concerns. It is not common to use tape after the injection of Restylane into the tear troughs. You should ask your doctor why he placed the tape. It is not likely to cause any problems.  Good luck,

As long as the results are excellent, the doctor may use any technique to get there. many of us have our own way of doing things. I don't believe that should be a problem for you to get treated or judge that the injection technique is not good. As long as the results are excellent, the doctor can use any technique they believe it gets them there. 

I would not say that it is "common," as I have never heard of it.  That does not make it "wrong" or even concerning.  One possible explanation could be that your doctor wanted to put a little bit of compression on the area to reduce swelling, but maybe he or she has another reason.  I would recommend asking your doctor directly what his or her rationale is for the tape.  In general, doctors have very good reasons why they do certain things and we are all different and have our own preferences.  This is not something that should be "concerning" to you and it is likely that it is even beneficial.  It is certainly not harmful, in any event.  If you get the answer from your doctor, please share it - maybe I'll learn something new!  Thanks for your question.

I, personally, have never seen tape placement after doing filler in the tear trough.  That being said, the best person to ask would be the injector as I'm sure they have a good reason for doing it.  They must have given you instructions as well in regards to the tape, so I'm sure that you could call their office and find out what the rationale is for the tape. Best of luck.  I agree with what others have said as far as what could be the possible reason for it...but best find out from the source.
