It looks like it is filler vs. festoon. I would try to get it dissolved and see if it gets better (assuming it was a dissolvable kind). If not, you might need to have it opened/explored for removal, in which case I would recommend going to an expert in periocular plastic surgery.
It's difficult to say without the benefit of a formal evaluation. See an expert who does facial shaping with surgical and non surgical methods to get a comprehensive option. Best, Dr. Emer.
