My bottom lip is bigger than my top lip what could cause that? (photo)

You should start out with 1cc of juvederm filler or restylane filler and go from there. You do not want to overdo too much filler in the lips. It also depends on the look you are going for too. You can always add more filler to the lips if needed. Just remember if you are going to do your lips and you do not want to bruise you should not take any aspirins or anything that will thin the blood since brusing can occur. One syringe is typically $500.

The normal ratio between lips is 2/3 on the bottom and 1/3 on the top, in terms of how the volume is distributed. Dermal fillers are great at addressing lip deficiency and making things look more beautiful. Find an experienced injector for best results. You should also prepare yourself to minimize bruising and swelling by following the tips in the video link below.Best wishes, Dr. ALDO

Thank you for your question. It is a common anatomy for many to have their bottom lip larger then their top lip. To change to appearance of the lips to achieve a certain desired result hyaluronic acid injectable fillers are a popular option. I would recommend an in person consultation with an experienced injector. Best wishes. 

this is your genetics!  if you want this improved there are many cosmetic treatments such as fillers, fat injections, and implants.  Best, Dr. Emer.

Thank you for sharing your question and photograph.  In the majority of patients their lower lip is naturally larger than their top lip and patients can choose to augment one, or both, through the use of a hyaluronic acid dermal filler such as Juvederm.  See an ASPS board certified plastic surgeon in consultation to have the best recomendations made.
