Immediately: you might notice some swelling and bruising. Usually it is minimal, however I tell everyone not to have important events scheduled for about 2 weeks, just in case there is a longer lasting bruise.
Next day: usually there is some bruising which can be covered up with makeup, and some swelling can be present. The swelling is due to filler absorbing water. It will improve in a few days. However, it can last as long as 2 weeks while the filler is settling in.
Two weeks: at this time the bruising and the swelling is gone. If there is residual swelling in one area or another, it can be given a little more time to settle in, or that area can be corrected with dissolving of filler. Also, if there is an area that appears under filled, more filler can be placed. I save the remaining filler in your syringe for two weeks, just in case a correction needs to be made.
