Are there any precautions to take after lip filler treatment?

As I get older, my lips are getting thinner and affecting my overall facial impression, so I've been worrying about it for a while. Based on a friend's recommendation, I am planning to get lip fillers. I have already had a consultation and intend to get just about 1cc for a natural look. What precautions should I take after getting lip fillers? Please let me know if there are any specific precautions I need to take that differ from regular fillers.
