Fatten Up Thin Lips

Human fat can be injected to augment the lips with a technique that involves using a syringe to extract fat from the buttocks or other fatty areas of the body. It is then washed with saline and re-injected into the lips with local anesthesia to maximize comfort.

You may want to stay close to home for the first few days after treatment, even though there's less swelling and pain with fat than with hyaluronic acid.

Look for a doctor with extensive experience using fat injections in the lips, as it can be lumpier than other fillers.
