Lip Cosmetic surgery providers often advise their patients that many options now exist for improving the appearance of the lips.
Most practitioners also admit that successful lip augmentation is highly dependent on the skill of the provider, with that skill stemming from many years of experience injecting the lips of many types of patients.
Moreover, the surgeon must master the various injection techniques. With many injectables, the benefit to the patient is an immediate return to normal, usual activities. A few surgeons offer a procedure known as surgical flap augmentations in which small sections of skin near the lips or inside the mouth are excised and added to the lips.
