Got 3 units of Botox on lower lip instead of filler by accident. What are the risks?

Botox is not generally used in the lower face, as too much of the product could have a negative impact on your ability to move your mouth, speak, and eat. Larger doses can also cause drooling and lip asymmetry. However, some practitioners do use smaller doses to soften the lines around the mouth or to create the appearance of pouty lips.If you are concerned about an adverse reaction, you may want to consider a follow up with your dermatologist or a second opinion from another practitioner near you. The affect of Botox will wear off eventually, typically within two to five months.
In the mean time, I have included a link to the uses and contraindications of Botox below.

Hello lucie c,
Fortunately, BOTOX effects are not permanent. Since you got a few units injected the product would wear off quicker and you shouldn’t have serious undesirable results. Best wishes! Dr. De La Cruz.

Thank you for sharing your concerns about your recent Botox treatment. First and foremost, your injector should know the different indications for Botox injections vs. filler injections. I strongly recommend you follow up with your injector to discuss how this occurred and potentially seek future care elsewhere. With that said, 3 units to the lower lip will soften the fine lines of the lower lip and possibly weaken your ability to purse your lips. The good news is, the effects of Botox in this area will not last long due to the high mobility in this area. You can expect the results to wear off completely in 3 months. In the future, be sure to discuss your treatment plan with your injector prior to any treatment. Best of luck, Dr. Kian.
