Is there a limit (safety) on how many dermal fillers a person can have injected in their face?

Thanks for your question, but it is a little nebulous and challenging to answer.  Is there a limit that can be injected at one sitting?  Is there a limit that can be injected over a certain time period?  Is there a limit to the different types of fillers that can be used at once or combined?  These are questions that are best answered by your injector.  I suggest you focus on selecting a well qualified and experienced physician injector who can help guide you through your options and use the right amount of filler to achieve your ideal results.  I have safely injected many syringes into a single patient at one sitting and gotten great results, but every case is different.  Best of luck!
