Hey. This is one of the most challenging kind of lips to be corrected by filler or neurotoxins. The best option here is a surgical approach via a modified lip lift with a wedge resection at the corner of the mouth to permanent lift the lips. The scar is well hidden and is continuous with the lip...
At 18 months, there is no filler left in your lip.
Having had it reversed should also confirm this.
Picture is a little bit difficult to interpret, but it looks like you have an Tyndel effect from filler which is probably not the correct diagnosis.
This could also be a mucosal.
I suggest suggest...
Most fillers dissipate over about six months.
Some patients report having long-term volume residuals long after the filler is gone.
This most likely does not represent the filler still being present, but rather a response to the treatment such as the development of inflammation and scar tissue...
