What can go wrong with Botox

What can go wrong with Botox?
The risks of Botox are minimal but include:

1/ Bruising from the injection.

2/The lateral brow peaking. This is comparatively common and is an overactive frontalis muscle pulling the lateral eyebrow too high. The cure is to place a tiny amount of Botox at the apex of the peak.

3/ A lower resting eyebrow position. This can occur when the forehead is treated to eliminate horizontal forehead lines. As the frontalis muscle is no longer pulling the eyebrows upwards, they slip down into their resting position. There is a risk that this resting position is considered too low, making the upper eyelid more hooded. This risk increases with age. This risk can be minimized by reducing the Botox dose delivered to the forehead and making sure the muscles that pull the eyebrows down are fully treated. If this eyebrow drop occurs there is unfortunately no quick fix. The Botox to the forehead will wear off and the frontalis will start to pull the eyebrows upwards again in a few weeks. The key is to use less Botox to the forehead in the future, but there is therefore an inevitable tradeoff between a smooth forehead with lower eyebrow, and a higher eyebrow but with more horizontal forehead lines.

4. Mickey mouse smile. This occurs when the Botox at the crow’s feet area prevents the orbicularis muscle tightening when you smile. The deeper smile muscle that lifts the corner of your mouth then lifts your cheek against a smoother lateral eye area, generating a single deeper "mickey mouse" crease. There is no quick fix for this. The appearance will improve as the Botox wears off and the key is to use less Botox to the lower parts of the crow’s feet in the future.
