Recurrent swelling 4 months after Restylane to rear troughs? (Photos)

Based on your photo's I would highly recommend you give your provider the opportunity to remove the product and treat that area. You can read horror stories about virtually anything and everything on any website, however, the horror stories don't always provide all of the information and don't apply to everyone.

Based on the photos provided it looks like you may have an allergic reaction, not to Restylane but other facial products you may be using on a daily basis. I suggest having a follow-up consult with your medical provider

Hello, and sorry to hear about the issues you are experiencing following your treatment with Restylane. It is possible the swelling can be a result of something else, as it is abnormal to have swelling appear randomly at 2 months. Were you swollen at all 1-2 weeks following the injections? When used properly by an experienced physician, hyaluronidase can have a fantastic outcome and successfully eliminate any filler that is present. And you are correct, filler can last longer than usual in the tear trough. Do you trust your doctor and his experience? If so, hyaluronidase may not be a bad option for you. In general, the side effects of Restyane may include:

1) Swelling
2) Light bruising
3) Irregularities
4) Lumps or bumps

I would recommend following up with your provider. Go over your routine with him or her, and communicate any changes in your habits that may have led to swelling in this area to rule out any other causes. I hope this helps, and I wish you the best of luck.
