Lip fillers typically last 12 to 18 months. However, it depends on your age and how fast your body metabolizes. Younger people tend to burn calories faster, so lip fillers don’t last as long.

Injectable lip augmentation techniques can be performed quickly in your doctor's office with little to no downtime. Fat injection is the exception, as the procedure involves liposuction before the injection occurs.

Before the injections, a topical or local numbing agent may be applied to ease discomfort. Sometimes, nerve block injections can be given before the treatment to completely numb the lips. Holding ice to the lips before injections also helps to numb the area and potentially helps with bruising and swelling.

After carefully marking the areas to be injected, very fine needles are used to inject the substance into your lips.

Following injection, ice may be given to ease discomfort and control swelling. But no firm pressure should be put on the treatment area.

Lipstick or other lip products are best avoided immediately after the procedure.

You will notice a difference immediately, and your lips should feel natural after you have healed.

You may experience mild pain at your injection sites. The pain should go away after 12 to 24 hours.

After 12 to 24 hours, your pain should go away. Your swelling should go away after 24 to 48 hours, but it may take up to a week.

If you want your lips filled before a big event, like a wedding, you should schedule the procedure for at least two weeks before to ensure you’ve completely recovered.
