In brief: Few & Minimal
Avoid Botox if you are pregnant or breast feeding or have neurological conditions.
When used appropriately for the reduction of lines of expression in the upper 1/3 of the face, Botox is incredibly safe. In my experience of 1000's of injections, the most common side effect is a small bruise (<5%). Headaches & swelling (rare). Eyelid or brow drooping (exceedingly rare).

Botox has a great safety record but experience is key to getting consistent results.

In brief: Several
Cosmetic Botox injections are generally safe and side effects are rare.
Most common side effect is bruising, especially when injecting in the crow's feet areas. Rarely, some develop headache, eyebrow droop or eyelid droop. Because Botox only lasts for 3 months, these affects will resolve with time. In the case of eyelid droop, it can be helped by iopidine eyedrops.

In brief: Botox side effects
Botox can work wonderfully for the majority of people but there are side effects and complications that you should discuss with your doctor. Side effects can include bruising (rare) that goes away in two weeks, temporary red bumps (expected) that go away within minutes to hours or a day, tenderness, headache (rare).
Complications such as droop are temporary and are in the minority of cases.

In brief: Generally safe
While most people have no problems when taking botox, side effects are possible.
In clinical studies, commonly reported side effects included droopy eyelids, muscle weakness, and difficulty swallowing. These side effects were generally mild and easily treated.
