Age-related changes around the lips and lip volume loss

Lip dermal filler is used to add fullness and restore proportion to the lips. Most patients typically require less than 1mL of filler to achieve their desired look. At Cityskin, we understand the importance of both volume and proportion when it comes to lip enhancement. Our experienced practitioners carefully assess the balance between the upper and lower lip heights to ensure natural-looking results.

Tailored to Individual Preferences

Every individual has unique lip characteristics and preferences. At Cityskin, we are often asked by patients for fuller lips, but we must be careful to pay attention to lip proportion as well as volume. When we assess lips prior to treatment, we look at the balance of upper to lower lip height.

If we look at the diagram below, you can see that the lower lip is approximately 1.6 times larger than the upper lip. In a Caucasian patient, we aim for the 1: 1.6 upper to lower lip ratio.

However, the 1: 1.6 ratio does not apply to patients across the world. The ideal upper: lower lip ratio in Asian patients is closer to 1: 1 so the height of the upper and lower lips are roughly the same height (shown in the diagram below).

While certain ratios may serve as general guidelines, we consider your personal aesthetic goals and features to create a customised treatment plan.



Most patients start with up to 1.0mL of dermal filler to treat the lips. If you want a much fuller lip, you can come back after 4 weeks to have another 1.0mL to give a more dramatic effect. If we use less than 1mL in the lips, we use the remainder in other areas – commonly in the cheeks or in the marionette lines (shadows around the mouth).

You will experience some mild swelling after having lip dermal fillers. Swelling varies from person to person and depends on how much filler you have used on the day. At Cityskin, we choose dermal fillers that minimise post-injection swelling.

We use the best dermal filler for lips at Cityskin, which is unlikely to cause lumps and bumps in the lips. We often ask patients to massage the lips for the first few days after treatment to help reduce the chance of very small lumps where filler has been injected.

Lip dermal fillers can be dissolved by injecting an enzyme into the filler. It breaks down the filler almost immediately, returning the lips to their previous shape.

The use of the longer lasting hyaluronic acid dermal fillers in the lips really isn’t recommended and, as a result, we don’t use these in the lips.

Having read experiences and advice from Plastic Surgeons in the USA, the general comment is that it is not FDA approved for use in the lips and it can give an unnatural look over time.

In the lips, we tend to like the filler that you used the first time. It has been used for years in the lips and gives a predictable result.

If you have an active cold sore, we would not recommend having lip filler. Wait until the cold sore has gone away before having treatment. If you take blood thinning medication, please let us know before your treatment as bruising is much more likely on these medications.

The dermal filler that we use at Cityskin usually lasts between 9 and 12 months but this can vary from person to person and the amount of dermal filler used.

We never use permanent filler at Cityskin. In our opinion, it is unsafe to use permanent filler as it cannot be dissolved if needed.

The lips are one of the most sensitive areas on the body along with the hands, tongue and genitals. Lip dermal filler can be uncomfortable without numbing the lips before treatment.

On the treatment day, we can offer either a dental block or numbing cream before treatment. A dental block is the procedure that you have when you have a filling at the dentists and involves 4 small injections of anaesthetic into the gum area. The lips go very numb within 5 minutes and the effects last approximately an hour.

Sensation in the lips can also be reduced using numbing cream. The cream is applied to the lips for approximately 20 minutes, providing a good numbing effect to the lips for approximately 45 minutes.

Bruising is not uncommon after lip dermal filler and the bruise may be noticeable despite covering makeup. The lips have a great blood supply and, even with the most careful injection technique, bruising can occur.
