Lopsided Smile After Evolence and Perlane Injections?

I had Evolence injected in my nasal folds and Perlane in the chin. One week later, I felt the chin was not filled enough so my dermatologist suggested Evolence on top of the Perlane already injected.

About 5 days after the 2nd office  visit, I noticed a "lopsided smile" and a swelling of one side of my lower lip. Because of the slight swelling, I am often biting my lip when I eat and this is causing a constant sore inside my lip. I am wondering whether this is because 2 products were used or just the injection technique.
