Yes. Botox is a very good treatment for this condition/problem or even post treatment outcome. A good and experience practitioner can help you even out this effect with Botox.
Yes. Good filler placement will lead to the desired effects and depending upon the particular filler used you can see effects from four to eighteen months or even longer. Most of the good durable fillers are very effective at creating improvement that lasts for many months after the procedure. I always like to have my patients start off with less than they imagine they need so that we can see how they do post treatment. We can always add but have more difficulty subtracting filler if there is an undesired outcome.
HI. Nice to hear from you in Vietnam. Usually the full effect of Botox takes about ten or so days so you may need to be patient for another day or two. But, if the physician who injected these muscles did not use enough botox you could also just need for to get the desired effect.
Yes it is safe to exercise 24hrs after botox treatment. Your Dr. advised you well. Have a good workout.
