Why do I have swelling one month after tear trough filler?

I suggest reversing the filler if you are still swollen or unhappy. this can be replaced with a different technique or filler type .  Best, Dr. Emer.

Although swelling after these injections is universally seen for a few days, prolonged swelling is usually due to the wrong filler being used, or too much volume being added. The tear trough is a delicate area and should not be treated in the same way as deeper and less forgiving areas like the nasolabial folds.
