I suggest waiting till you are feeling better before doing any cosmetic treatments. There is a higher risk of problems with filler injections if you do not. Best, Dr. Emer.
Thank you for asking your good question. It would probably be safe to receive injections of Restylane with a resolving cold; however, it would not be prudent. Procedures should not be performed when sick due to potential increased risks to yourself or other patients around you. It is best to delay treatment for your safety. I hope you feel better soon.
