I had fillers/Botox done yesterday and I don't see a huge difference, when might I see a HUGE difference?

You will notice a difference with your botox treatment after about 4-7 days and 2 weeks for the final result. Generally fillers are instant results but then take about 2 weeks for the swelling to subside and the product to settle for the final results.

You should
expect to see some initial results from you Botox treatment by 7-10 days, with
your maximal results by 14 days. With filler, you will see your initial results
immediately after your treatment, and by 7-14 days, you will see your final
results.

The onset of effect of Botox after it is injected is approximately 3-5 days for most patients.  In some cases it may take up to 2 weeks to see the full results.  Results from filler can be seen immediately that there is usually some swelling associated with filler injections.  It can take 1-2 weeks before the final outcomes can be judged.
