“It wasn’t the same… One had it and the other didn’t. Only here he raised this eyebrow here, and here he raised it crookedly. Look what a joke. We did the thing to look good and it turned out ugly,” Myra said regretfully.

The situation raised doubts among observers about the possibility of asymmetry even when the procedure is done correctly. To clarify the matter, plastic surgeon Maeve Corallo explains that yes, this can happen, and it does not necessarily mean a technical malfunction.

According to the expert, asymmetric muscle response is common because no one has a perfectly symmetrical face. Muscles of different strengths and shapes can react at different speeds to the poison. “The poison does not paralyze both sides at the same time. One side can respond in one day, and the other after only two days, and this creates a temporary asymmetry,” he says.

Post-application behavior also affects the result. Physical activity, lying down immediately after the procedure, or moving the area excessively can cause the product to transfer to adjacent areas, modifying the desired effect. “These precautions must be respected for the first five hours to avoid its spread to unwanted areas,” the doctor advises.

Another common situation is the formation of small bruises during application. When this happens, the material may be less absorbed at that point, resulting in a weaker stop.

Despite the aesthetic discomfort, the surgeon emphasizes that these changes are usually correctable. Most cases can be corrected with small nutritional supplements, as long as there is no ptosis. However, it is necessary to wait up to 15 days for the poison to take full effect before any touch-up.

There are also cases where immediate correction is not indicated. When a patient does not return for review or when the brow is too low, the approach is to stimulate the muscles most at risk to speed up natural healing.

Without intervention, the asymmetry tends to disappear on its own between three and six months, which is the maximum duration of the disease. Dr. Maeve also highlights the importance of choosing a qualified specialist, as the procedure requires millimeter precision.

“The doses applied are minimal, 0.01 ml to 0.02 ml per drop, and any difference in distance or depth can affect the result. Therefore, it is essential that the professional knows the anatomy in depth,” he warns.
