Usually we don't see swelling intermittently from Restylane or Juvederm as the molecules can only hold so much of your water and it holds it to the max until the Restylane or Juvederm is dissolved completely. Deeper fillers and combination fillers may create different reactions, even...
It is very common to have Botox between the eyebrows done at the same time as Restylane in the nasolabial folds. Please be evaluated by an experienced injector.
Regarding: "I Had Sarcoidosis 15 Years Ago. Can I Have Restylane Injections Safely?"
To my knowledge, Sacoidosis has nothing to do with Hyaluronic acid found in Restylane and Juvederm and use of these fillers should not aggravate that condition.
