I am a male 26. I just got 16 units of Botox injections on my forehead yesterday, how long will I see results?

A dosage of 16u of Botox may be a bit low. We typically start with 25u Botox to treat glabellar frown lines, and up to 50u for an entire forehead, depending on one's examination. Sit tight for at least a week from injection to judge your results, and consider following up with your surgeon if you are not satisfied at that time. Hope this helps. Dr Joseph

Botox will take several days for results to show.  Some patients will see a difference within 3 days, other may take up to 14 days.  The botox will start to work gradually and then take full effect within a month.  Botox is usually needed every 4 months.  Good luck.

Botox can take up to 12 days to kick in fully.  The lines you are concerned about will be lessened to the extent that they are caused by muscle movement.  If the lines have been dug in deep over time by repetitive muscle movement it may take several treatments to really soften the lines.  If the lines are truly static or not caused by muscle movement you may have to look at other solutions such as laser resurfacing, fillers etc.
