The Facial Filler (dermal filler) injection feels similar to a tiny pinprick. Done properly, any discomfort should disappear in a few moments to a few minutes. Facial Filler (Dermal Filler) injections into your lips may cause some minor swelling for a few hours after the procedure. Dermal Filler injections might feel a bit unsettling for some patients, but they should never be painful.
