After your treatment, you may have some
redness, bruising and swelling; these reactions are normal and usually subside
within 2 days, however some of these symptoms may persist for up to 1-2 week. If the pain still persist I recommend you go see your the physician who injected the treated area.
Best of luck!
Typically swelling and pain resolves within a week after Perlane injection- either way you should follow up with your cosmetic surgeon regarding this.
You didn't state where the filler was placed, so sensitivity could have to do with that. Swelling can persist for 10-14 days, but any pain should have subsided long before that. If you have questions or concerns, you should always return to your injector to be checked.
