What is the maintenance like on lip fillers?

Once you have achieved your desired volume and shape you can anticipate having the lips touched up every 6-9 months.  The amount needed at touch up will depend on how quickly your body dissolves the product, but you if you go for regular touch ups you will probably not need as much product as was originally injected.

Lip fillers generally have a shorter duration because the lip is such a dynamic structure. I think it is reasonable to expect a duration of 6-12 months depending on the filler used. A new filler has just gained FDA approval for use in more dynamic areas of the face, such as the lips. The manufacturer focused on making it a highly elastic product that will hopefully last longer. The fillers are called Refyne and Defyne. You should ask about these specifically next time you can.

Thank you for your excellent question. If you like the  shape  and volume of your lips , I would suggest to have a touch up performed on your lips  every 3 months . You would need much less than your original enhancement,and it will keep your desired enhancement longer.
