Uneven top lip, should I get more lip filler on one side? (photos)

Thank you for sharing your concerns and posting your photograph. The easiest next step would be to fill the smaller lip. If this is performed carefully, it should match the opposite side. Make sure you have expert injectors performing your treatments.Good luck,

The first thing I recommend is to arrange a follow up appointment with your doctor to assess and make next step plans. Filler takes 2 weeks to settle, I would not recommend having any further treatment until this time. 
Lips can swell between 10-20% over the first night following treatment which can distort the end result which settles in that 14 day period before review. If your lips are asymmetrical this may have occurred due to swelling at the time of treatment making it difficult to assess symmetry. It is always better to put less in and make them even at the time of treatment. If further filler is required at a second appointment this can then be administered. It is easier to add more than to take it away (although that is possibly with hyalase).
Please ensure you see a qualified medical doctor for your treatments. 

Thank you for your question. If you are happy with your results, then I suggest having a little more filler injected into the smaller side to help even out the lips. I recommend having a follow up with your injector for evaluation and treatment. Best of Luck!

You can get a little more injection into the side that is not as full as the other and that should get you what you desire

If you are happy with the size of your lips then get a drop more filler and even them up. This can happen , even with the best injectors, because lips can swell while injecting making it hard to get perfect symmetry. that is why some doctors have patients come for touch up in two weeks. Tell your doctor where you want your volume and have them do a drop at a time . I would not dissolve unless you do not like the size. 

Thank you for your question and for submitting your photos. Your two week post injection photos seem to show that the asymmetry has softened. You should consult with your injector about the best options. You are correct that if you add more you may get into a "seesaw" situation that will never be exactly symmetric. Best to be examined
