A surgical rhinoplasty is required to reduce the bulbous tip cartilages in addition to filling in the cleft between the two lower lateral cartilages. Suture techniques, a conservative cartilage removal, and possible cartilage grafting will help make the nose look more refined.

Thanks for your post and photos. You have a slight indentation caused by a bifid tip cartilage shape, which is very common. A safe injection may offer you some temporary improvement, however, the benefit will naturally disappear and have to be repeated every 4-6 months to maintain. Additionally, injections can be associated with some skin side effects and even skin loss for some. Surgical options include rhinoplasty. An open approach procedure can be performed to offer you lasting, permanent benefit in an experienced surgeon's hands. Consider an in-person consultation with a reputable rhinoplasty surgeon to discuss your best options. Best wishes.
