Can the Doctor Test Us Beforehand to Make Sure We Are Not Allergic to Restylane?

All good feedback from panel members.  As thoroughly stated, there is no reason or indication for an allergy test prior to treatment with hyaluronic acid dermal fillers.  

However, if you believe that this would offer you more peace of mind, then moving forward with this is not unreasonable if you pay for the product and the practitioner's time to render the test.  Keep in mind that you will need to absorb the cost of the syringe (whether half or full syringe) once it is used on you regardless of whether or not you move forward with a complete treatment.

Since Restylane and Juvederm are made of hyaluronic acid, a substance found in all animals (including humans) we theoretically cannot be allergic to it.  Reactions to other products that contain collagen have been reported and therefore skin tests are used for Artefill and the older collagen products Zyplast and Zyderm, but not for hyaluronic acid products.  

Allergies to the original bovine collagen filler was about 10%.  For this reason routine allergy testing was essential.  The incidence  of allergy to Restylane is so rare (stated to be less than 1% but seems to be 1 in 1000 or less in my experience) that routine testing is not felt to be necessary.

If you feel you must be tested, be prepared to pay for this request.  The smallest volume of Restylane in a unit package is 0.4 ml.  This product can be used as a skin test.  What about having the doctor store this open syringe for your use a couple weeks later if you do not react?  I would no recommend this.  Once the syringe has been put into use, the sterility of the product is compromised.
