I had Restylane done 2 weeks ago. Although the doctor said it doesn't add any volume, it did. Could this be swelling?

Most swelling typically subsides after 2 weeks, so you are likely looking at your final result!  Happy to hear you are enjoying your "Amazingly nice" results!Best Wishes,

After two weeks, this is most likely your final results. The filler results will gradually resolve. Hope this helps.

Hi. If the filler was done 2 weeks ago, most of the swelling has subsided by now and you are seeing the final results. Congratulations, I am happy you love your results.

Happy to hear you have this nice result. After two weeks, most of it will last! Restylane skinboosters are brought to the market to improve skin quality without adding volume or strength but in fact, it is just the same NASHA gel as the fillers, but in smaller particles.  It is a 'miniature filler', so don't be surprised when it fills or strengthens. 

Thank you for sharing your question. Restylane actually does
add volume to the area where it is injected! At the two-week mark, most of the
swelling should be resolved, although you may still be experiencing some swelling.
It sounds like you have a great result! Enjoy! Best, Dr. Griffiths
