Many patients do not understand that a treatment with a fill, especially when a needle is used to place the dermal filler, rather than a cannula, that there can be a lot of trauma to the tissue, especially when the filler is placed under the eye to treat lower eyelid bags and tear troughs.
Lumps, bumps, swelling and bruising are very normal consequences of an injection of filler in the lower eyelid and they can all result in the appearance of too much filler at a week after an injection.  These injection sequelae normally last at least 3 to 4 weeks and can last even longer in some circumstances.
