Uneven Swelling After Restylane in Tear Trough

Hi Jordan,
Unfortunately it is too early to tell for certain what is causing your swelling.  Hopefully you are taking anti-histamines, and have notified your injecting physician of your swelling.  At this point follow the advice of your injecting physician.  I hope that your swelling resolves quickly.  Be well.

All good information and responses from the panel members.   Just like the lips, the tear trough areas can experience delayed swelling well after the procedure is done.  Oftentimes, this is related to the patient massaging or manipulating the area.  Being that you were experiencing itching to the eye prior to your treatment, you may have inadvertently provoked this reaction or exacerbated any swelling that was related to the injections.  Early intervention following bruising or swelling is beneficial.  Always be proactive in notifying your practitioner of any concerns. 

As the swelling could be related to an allergy to the dogs, the photograph can't allow us to determine if it was the filler that caused it. You should see your doctor and have them examine you to see what caused the problem. Antihistamines and ice packs may help, avoid bending over at the waist, avoid exercise, don't strain (if you're constipated) avoid hot showers, until this lessens. It may be overcorrection of filler and if your doctor believes this to be the case then it can be treated with hyaluronidase.

It may be too early to tell if it is product or just swelling. In all probability it will be swelling.
It is not uncommon to swell differently on either side. Anatomy and injection techniques will differ a little. Don't worry if one tear trough was different than the other -- they usually are.

Odds are that you slept on your left side and the sinus congestion and swelling from the allergies pooled on that side. Try sleeping on your back, on 2-3 pillows. Avoid all salt, drink lots of water and be patient. In hind-sight, the appointment should have been postponed until the allergy problem was better, but there will be no long term problem. I do not think you were incorrectly injected, but go see the doctor and maybe some antihistamine/decongestants would be recommended.
