I got Belotero injected under my eyes yesterday. How long will it take for the filler to settle down?

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

Belotero is hydrophilic, meaning that the product absorbs water molecules.Swell-x pt can reduce localized swelling as it functions as a citrus bioflavonoid. 
The bruising can be resobed faster with the application of Bruise Balm. 
Apply Bruise Balm from Plato's Medicinals to reduce inflammation in the area. See link.
If it persists, ask them to dissolve this product with hyaluronidase.

Good Afternoon and thank you for your question. With any injectable procedure it typically takes 2 weeks for the product to completely settle in.  During the 2 week period you will have swelling and possibly bruising, which are common side effects.  Once the 2 weeks have passed and these side effects have subsided you are able to evaluate your final results.  In some cases the under eye area may take even longer as it is a very delicate area.  If you have any concerns regarding your results be sure to consult with you expert injector.  Best of luck to you.

I would give it 2 weeks to settle down and see what your final result is going to be. If there is residual lumps, it can be dissolved with hyaluronidase.

Thank you for your question. The area you had treated is very sensitive and can cause swelling. It can take up to 2 weeks for all swelling to resolve and see your final results.
