Restylane

Some swelling 24 hours after under-eye Restylane is normal and expected. The skin there is thin and the tissue underneath is loose, so fluid and mild bruising show up more than they would elsewhere on the face. Hyaluronic acid fillers like Restylane also attract water, which adds to early puffiness. This typically peaks in the first day or two and settles over one to two weeks. Cool compresses, keeping your head elevated, and avoiding salty food or alcohol can help it resolve faster. Aspirin, ibuprofen, and fish oil can prolong bruising and swelling, so hold off on those unless medically necessary. What separates normal swelling from a problem is progression: if it's getting worse rather than better, or you notice significant firmness, discoloration, or asymmetry, that warrants a call to your injector rather than waiting it out. If you notice blanching or white, dusky, or blue skin, pain that is severe or steadily increasing, coolness of the skin, vision changes, or any stroke-like symptoms, that needs to be evaluated the same day, since these can signal a blocked vessel that can be reversed with hyaluronidase when caught promptly. Without seeing the area directly, it's hard to say definitively, so have the treating provider take a look if you're unsure. A quick in-person check is the safest way to confirm things are on track.
