Fillers can help improve the appearance of a deep chin crease. There are various fillers that work well in this area. Depending on the depth of the crease, I usually use fillers from the Juvederm or Restylane family of products. More important than the type of filler is the skill of the injector, so make sure you are under the care of an experienced physician injector. Best wishes.
Hello. You have amazing lips and skin! Consultation is vital with a Board Certified Plastic Surgeon, Dermatologist, Facial ENT, or Certified Aesthetics Nurse Specialist. The chin muscle aka Mentalis needs several units of a neuromodulator: Botox, Dysport, Xeomin. This process will relax the muscle thus relaxing the crease. Amazing results! Some dermal filler might be required just to side left and right side of the chin for a more oval smooth round lower face.
