You should not find your Bellafill injections painful, no. Your provider at West End Plastic Surgery can apply a topical anesthetic to your skin prior to your treatment. This doesn't numb the area completely but it desensitizes the nerves in your skin enough for you to feel comfortable. After your Bellafill injections, you might experience a mild stinging sensation for a day or two. This is a normal side effect that should resolve without further treatment.
