When Should I Go for Botox Touch-up?

The effects of Botox on the SKIN may take longer than the effects on the muscle.
While the muscle is generally weakened in 3-5 days, it can take several weeks to even months to see an effect on the skin.
Let me explain with an analogy. If you wear a pair of pants all day long, you will form many wrinkles from walking and bending. At the end of the day, you will have many wrinkles but the next morning, after being on the hanger all night long, many of the wrinkles will have worked themselves out.
Think about how long you have been forming that wrinkle between your eyes, 20 or 30 years? Give it time to relax.
The real test is if you attempt to frown and you see little muscle movement, then the Botox has accomplished it's primary goal. Give it more time for the wrinkles to relax and work themselves out. If you still see significant muscle action with attempted frowning, then I would return at the two week mark for more Botox.
I hope that is not too simplified of an explanation.

Hi Heather,
10 Days should be long enough to see the result of your Botox injections. We schedule 2 week checkups every time we offer a new procedure for a patient. This way, we can address all concerns while the results are fresh.
Lots of good advice from the other practitioners in that the nasty frown line may actually require a bit of dermal fillers to correct. This is not all that uncommon in this area. Check with your practitioner to be sure. Good luck.

Botox takes between 3-7 days to work, but I like to give it up to 2 weeks to be sure. I routinely have my new patients come in at 2 weeks to evaluate if they need additional Botox in any given area. Once the proper number of units is determined for any given area, this amount tends to be quite stable over time. As a side note, your line in between your brow may not completely resolve with Botox. If your muscles are still moving, then more Botox is the answer. If your muscles in that area are not moving anymore and you still have a crease, you may need a little bit of filler placed in there. I would recommend talking to your doctor.
