Continue reading to discover the answers to these and other lip filler FAQs.

What Is Lip Filler?

Lip filler is a gel-based product that is injected into lip tissue to improve size, shape, and symmetry. It’s performed as an in-office procedure, usually takes 15-30 minutes, and produces immediate volume enhancement.

Other than mild and temporary swelling, lip injections carry little to no risk and don’t require any downtime.

How Do Lip Injections Work?

Most lip fillers are comprised of cross-linked hyaluronic acid particles suspended in a gel base.

Hyaluronic acid is a naturally-occurring substance responsible for cushioning joints and hydrating skin. As such, when injected into soft tissue, hyaluronic acid readily attracts and holds moisture.

This instantly plumps lips and results in a fuller, softer, and suppler pout.

Do Lip Fillers Hurt?

Although lip filler is administered with an ultra-thin needle, injections can cause some mild discomfort. Fortunately, most lip filler formulations contain lidocaine to numb the area and reduce pain.

A topical anesthetic can also be applied pre-treatment to improve patient comfort.

How Long Does Lip Filler Last?

If you are contemplating injections, you likely want to know: How long does lip filler last?

Lip fillers produce temporary results than can last six-to-nine months. Longevity often depends on the product used, injector technique, patient goals, and patient metabolic rate.

Most patients undergo touch-up treatments after six-to-12 months.
