Immediate side effects of botox

You would notice any complications within 10 days or so. After that period, you are safe and will continue to notice improvement over time.

Negative side effects of Botox show up early

Typically side effects of Botox such as a droopy eyebrow or eyelid develop within the first 10 days, and the duration of this is variable, and never longer than 4 months. If Botox is injected by a highly trained and experienced physician, the likelihood of any side effects is remote. ~ Dr. Benjamin Barankin, Toronto Dermatology Centre.

Adverse effects of Botox such as droop may be seen in a few days

Although it is rare to see a droop with Botox, it can be seen in the first few days and become more dramatic over a week, or even two. No muscular relaxation is permanent and it will go away on its own over 12 to 16 weeks. Some droops can be improved with adjusting Botox in other areas, such as treating depressor muscles of the areas, or even fillers.

Botox effects seen in 2-3 days

I counsel patients that effects of Botox are usually seen at 3-7 days, are maximal at 2-4 weeks, and disappear by 3-4 months.  Occasionally, patients may start to notice wrinkle improvement within 24-48 hours.

How Long for Botox Side Effects?

Hi MMM.  If you are going to see a side effect like eyebrow or eyelid droop this will normally be present after 2-3 days.  We normally advise patients that the full effect of Botox will be seen within 1 week, but most of the effect is within 72 hours.  

If you do not have any eyelid or eyebrow droop by that time, you should be free and clear.

How long does it take for Botox to work?

It generally takes 3-10 days for Botox to work--and this includes undesirable as well as desirable results. And then it's effect will wear off in approximately 6-9 months--both desirable and undesirable effects. So even if you do have some undesired droopiness, it is temporary.

Negative effects of Botox should appear within 7 days.

If a negative effect is going to occur after Botox it usually appears within 6 to 7 days. If you go past 7 days it would be extremely rare for negative effects to manifest.

Negative side effects of Botox

Most of the time Botox kicks in within 7-10 days so any negative side effects will have appeared by then. Hopefully you won't have any to begin with, though!
