Why is it that every time I have lip fillers put in they look like fish lips?

I suggest you go to an expert injector.  Sometimes injected in the lips and around them help to give a balanced look.  Cannulas help improve the results and decrease pain/swelling and bruising.  You need a formal consultation, and to post photos on here for us to give a better answer. Technique is very important with lip injections so only go to the best.  Best, Dr. Emer.

I appreciate your concern, but perhaps your injector is either too aggressive, using too much filler, or it is being placed in the wrong area. I would recommend conservative lip augmentation with Hyaluronic Acid, like Juvederm plus. Another option is fat transfer which is more permanent. Seek out a board certified plastic surgeon in your area, Good Luck

The initial response of a HA filler is to attract water to itself, thus swelling insures! Discuss with your filler doctor.....

I'm not sure how we can answer your questions without evaluating your pictures. Generally the fish lips are due to over injections or injection into the wrong space. Please seek consultation with an experienced and board certified dermatologist, facial or general plastic surgeon for such treatments for optimal results.
