How long does lip filler last?

The short answer

Most hyaluronic acid lip fillers last around 6 to 12 months. Some people notice their result softening a little sooner, and some keep a subtle result for longer. There is no exact date when filler “runs out”: it fades gradually, and your lips slowly return towards how they looked before treatment.

Why lip filler does not last forever

Hyaluronic acid is a substance your body already makes, and dermal fillers use a stabilised form of it. Over time, your body breaks the filler down naturally.

The lips are one of the most mobile parts of the face. Talking, eating, drinking and smiling all mean constant movement, so filler in the lips tends to break down faster than in areas such as the cheeks or chin, where firmer products are used and there is less movement. That is why cheek filler often lasts longer than lip filler.

What affects how long it lasts

Several things make a difference, and most of them vary from person to person:

• The product. Fillers are made with different properties. Softer, more flexible gels suit the lips but may break down sooner than firmer ones.
• The amount and placement. A small, natural-looking treatment may look less noticeable as it fades than a larger one, even if the filler lasts a similar time.
• Your own metabolism. Some people simply break hyaluronic acid down faster than others.
• Lifestyle. Smoking and a lot of unprotected sun exposure affect the skin generally and may shorten results.

What happens as it fades

Filler does not disappear overnight. Most people notice their lips gradually becoming a little less defined or hydrated over several months. Because the change is slow, it is often noticed in photos before it is noticed in the mirror.

Making the most of your result

• Follow your aftercare advice closely in the first two weeks, while the filler settles.
• Protect your lips from the sun and keep them moisturised.
• Avoid smoking, which affects skin health and the area around the mouth.
• Base any top-up on how your lips look and feel, not a fixed calendar.

When should you top up?

There is no need to top up on a schedule. Many people choose a smaller top-up when their result starts to soften rather than repeating a full treatment. Your practitioner will look at how much filler remains and advise whether a top-up is needed at all. Adding filler too often, before the previous treatment has faded, is something a careful practitioner will avoid.

Can lip filler be dissolved?

Hyaluronic acid filler can sometimes be dissolved after a clinical assessment, for example if there is a complication or a result has not settled as expected. Dissolving is a medical treatment in its own right, with its own risks, and it cannot guarantee a return to how you looked before. It is one reason the type of filler used matters.

Is lip filler right for you?

The best way to find out is a consultation, where your lips, facial balance and medical history are assessed and you can ask questions without any pressure to book. You can read more on our lip filler page, or get in touch to arrange a consultation in Boroughbridge or the Billingham area.
