Question: What are the benefits to using an injectable filler made with human-based collagen, as opposed to using an animal-based product?
Answer: The biggest advantage of using human-based collagen products over animal-based collagen products is that there is no need for allergy testing in patients due to the fact that you cannot have an allergy to human-based collagen. With that said, I have essentially abandoned human-based collagen products over the hyaluronic acid products simply due to the fact that the hyaluronic acid products work much better and last much longer.
