Wait two weeks before touch up
It is typically best to allow two weeks for Dysport to take full effect. If a touch up is performed too early, this could negatively effect your outcome. After two weeks, you will have achieved your maximum correction, and your doctor can accurately assess if a touch up is needed. It is always recommended to consult with your physician to determine his/her specific recommendations.
More lines after Dysport?
From your description, it is possible that you are developing what we sometimes call a quizzical brow. This happens when the lateral segment of the large, fan-like frontalis muscle that lifts your brow, is strong, which is not the case for everyone, and/or has not been treated with enough or any botulinum toxin-A such as Dysport. This can happen to one or both sides and the wrinkles you describe are usually most prominent just above the lateral arch of the brow. I would see your dermatologist or plastic surgeon to see whether or not this is the case, because just a few units of BTX-A such as Dysport will correct the problem, and can be given the next time around to prevent this from happening again. Your doctor may also inject just a few units under the lateral brow, at the temporal fusion plane, to allow your entire brow to remain nicely and subtly arched rather than go the opposite way and become flat or droopy.
Uneven Dysport Results
It is important to give the Dysport the time it needs to set in correctly before doubting the outcome. It can take sometimes up to a full 14 days before it is fully developed. At this point it is an option to go back for a "follow up" or "touch up" if you do need to tweak things a bit- this is totally normal.
Final results from Dysport
It can take 10-14 days for full effects of Dysport (or Botox) to kick in. I don't recommend going back to the doctor until that point as I don't do touch-ups until this timeframe has passed. Each muscle will respond to the Dysport differently (and each side even) so it can take a bit of time for all muscles to see full results. If you do touch-ups too early before that, you can knock the muscle down too much, and then you won't like the result at all. So be patient. Then assess.

Botulinum Type A Toxins Take a Week or More Before Final Results are Seen
After botulinum toxin type A injections it may take a week
or more before you see the complete results. At first the relaxation of the
muscle may appear a bit asymmetric, and that could possibly be related to
slight differences in the injections or dosing. Many times these asymmetric
areas of movement will even out, but it may take a week or more.
The lines that you see forming above the left eyebrow, on
the more mobile/animated side, are the result of some frontalis muscle that is
not relaxed and still has function. The lines form, and may appear a bit
exaggerated, because the muscle above this area (higher up on the forehead) is
relaxed and has less movement. Time will tell how this will all settle and if
it will even out. If these lines persist above the left eyebrow, a small amount
of Dysport can be added to this area to provide additional relaxation and
better symmetry with the right side.
I would give it about a week in order to see what your true
results will be. If you still have concerns after that time contact your
physician to discuss your options. Best wishes.
It is still too early to judge the final result from your injection two days ago.
I would wait 7-10 days and evaluate for symmetry at that time. It is not unusual for the effect to come in earlier or differently on one side compared to the other. It almost always will even out after the muscles are fully relaxed.
