Lip Fillers: General Principles for a Natural Look and Their Limits

Lip filler treatment usually involves injecting a hyaluronic acid filler into the lips to support volume, shape or definition of the lip border. It may be chosen for various reasons, such as lips thinning with age, asymmetry or a less defined lip border. In this article we look at the general principles for a natural look and the limits of the treatment.

Principles for a natural look

• Proportion with the face: lip size is assessed together with the nose, chin and overall facial proportions, not in isolation.
• Balance between upper and lower lip: in most faces the lower lip is slightly fuller than the upper; this natural balance is respected.
• A gradual approach: starting with a small amount and adding at a follow-up if needed can give a more controlled result.
• Your own lip structure: the aim is not to copy someone else’s lips but to support your own anatomy.

How is it done?

Before treatment, expectations are discussed, medical history is taken and the lips are assessed. The procedure is usually short; numbing cream or fillers containing a local anaesthetic may be used for comfort. Swelling and tenderness lasting a few days afterwards are normal, so the fullness seen in the first days does not reflect the final result.

Possible side effects and limits

Swelling, bruising, tenderness and temporary asymmetry are common and usually resolve on their own. Although rare, more serious complications can occur, such as infection, nodules or circulation problems if filler enters a blood vessel. It is therefore important that treatment is performed by a physician familiar with facial anatomy and in suitable conditions. Filler is not always the right option for very marked changes in shape or structural problems of the lip.

People with a history of cold sores should mention this beforehand, and treatment is usually postponed during pregnancy and breastfeeding.

Frequently Asked Questions

How long do lip fillers last?

Hyaluronic acid fillers are absorbed by the body over time. Duration varies with the product, the amount used and individual metabolism.

How long does swelling last after lip filler?

Swelling is usually most noticeable in the first few days and then decreases. The final look is generally assessed after a few weeks.

What if I am not happy with the result?

Hyaluronic acid fillers can be dissolved by a physician with a special enzyme if needed. Whether this is suitable is assessed at a consultation.
