Walk out of the clinic and you’ll see no difference, which is completely normal. The first change tends to show up two to four days later, and by about two weeks the result is usually all there. Strong muscles can take longer, and some areas keep settling for a few more weeks.

According to Dr. Monisha Kapoor, aPlastic Surgeon in Delhi, “The toxin takes a few days to settle into the muscle, so day one looks no different from before. Movement starts easing around day three or four, and the result is clear by the two-week mark. A review at that point is the right time to judge the outcome and decide whether any adjustment is needed.”

Why doesn’t Botox work straight away?

• The toxin has to reach the nerve endings and block the signal to the muscle, and that takes a few days.
• The muscle doesn’t switch off at once. Frowning just starts to feel odd, a bit like the muscle has gone tired.
• Skin lags behind the muscle. Even after the pull stops, the lines need a little while to soften, so the smoothing comes last.
• Little bumps at the injection points go down within hours. Don’t read anything into them.

Botox isn’t only for frown lines, and the neurotoxin and fillers page shows which other areas can be treated.

How do you get through the wait?

• Leave the treated spot alone for the first few hours. No rubbing, no pressing, no face massage.
• Skip the gym and the steam room for the rest of the day, unless your clinic has told you otherwise.
• Take a photo before treatment. Put it next to one taken at two weeks, and the difference is far easier to see than in a mirror on day two.
• Don’t book the review too early. Two weeks is about right, because by then the result has settled.

Forehead lines bring in plenty of people, and the forehead treatment page covers how that area is treated.

What determines how long Botox takes to start working for you?

• The area treated. Strong muscles can take a little longer to settle than small ones.
• The product used. Studies show onset can differ by a day or two between brands.
• The dose placed, and how precisely it was placed.
• Your own response, which really does vary from one person to the next.
• What the surgeon sees at the review, once the full effect has set in.

Key Takeaways

• First changes usually appear within two to four days of treatment.
• The full result tends to show around two weeks, and sometimes closer to a month.
• Judging on day one or two usually leads to unnecessary worry.
• Area, product, dose and your own body decide your timeline.
• A review at about two weeks is the right moment to ask about any adjustment.
