What can I do to remove old scar tissue from my lip? Is it safe to use Juvederm for augmentation? (Photo)

In person consultation is the key. The most important
thing is the determination of how thick and deep the scars are as that will
determine what the next step is.
If the scar is thin the need for microfractionated (smaller fractionated
lasers) carbon dioxide lasers as a scar remodeling technique vs scar
revision. Scar revision could be considered if the scar is deep and
thick, but it will leave another scar so if the thickness of the current scar
is minimal again I would say that lasers will give you the best long term scar
outcome.
The thickness also matters as far as the fillers that can be used. If the
scar is almost full thickness that can make the injection of fillers more
difficult and an experienced person is vital. That said, it can also be
very helpful too to even out volume deficiencies.
I bet the scar is a little thinner than thicker as the mole removal should have
been a superficial removal not deep.Thus seeing someone who can do microfractionated lasers and filler would
be the best option.Not all carbon dioxide
lasers and laser surgeons are created equal so make sure you discern the best
in your area.

Thank you for your question and photo. Fillers can be very helpful in raising scars and reducing asymmetry.However, if the scar tissue is 'tethered' to deeper structures, filler can actually accentuate the deformity byraising the surrounding 'untethered' areas to a greater degree. In an in-person exam, your surgeon should have a good idea of the texture of the lip tissue and scar. Scar revision prior to lip augmentation is also anoption, but requires much greater time and effort. Obviously, working with an experienced injector is veryimportant. Good luck to you.
