the ultimate guide to LIP FILLER

We are pleased to offer Lip filler at our London clinics.

In youth, the lips tend to be full and voluptuous and as we age they lose volume and shape, becoming thin and flat. As a result, lip enhancement has become a popular treatment in anti-ageing clinics. 

Skin naturally produces hyaluronic acid (HA) when you are young, which keeps the skin full, hydrated and elastic. Dermal fillers mimics the effects of HA resulting in reduced facial lines, scars and increased plumpness of skin and lips.

Dr Asha aims to subtly reshape and redefine lips.

Before you receive a treatment, we’ll listen closely to your concerns and aspirations, answering fully any questions you may have, to ensure that you are delighted with the natural-looking results you’ll achieve.

Majority of clients are suitable for Lip Filler treatment. A full medical history will be taken from you. 

Those not suitable for Lip Filler include: pregnant and breastfeeding ladies as there is a current lack of data to suggest if treatment is safe during these times. 

Following an in-depth consultation where I perform a full facial analysis, I will be able to advise what I feel would provide you with the best and natural looking results. 

If lip filler is not suitable for you, I will always be honest and provide an explanation as to why. 

Lip Filler should only be administered by adequately trained medical professionals. Medical professionals i.e Dentists, Doctors, Nurses. They should have undergone the appropriate training (ideally be Level 7 qualified) and have completed a number of treatments so that they have a greater understanding on how to administer Lip Filler according to individual needs.

Sadly in the UK, it is an unregulated industry and non medical professionals are currently able to offer filler treatments. This is very dangerous due to the risks involved in having treatment. A high level of medical skill is required for treatment to be performed safely and successfully and should there be any complications that arise, you need to ensure that they can be dealt with safely to prevent any long lasting effects.  Be careful of who you trust, your face is precious.

Dr Asha has been a Dentist for 10+ years and therefore is very adept at providing injectable facial treatments. She was one of the first students to achieve a Level 7 (Masters equivalent) in Aesthetic Medicine and also has a history of being a lead trainer with one of the most reputable aesthetic training schools – helping medical professionals start their career in aesthetics. 

Having performed 5000+ aesthetic treatments over the last 5 years, you can be certain you are in safe hands!

The different areas of the lip that can be enhanced includes: 

  • the lip border – for definition
  • the lip itself – for volume,
  • the corners of the lips – for downturned corners
  • the philtrum (midline groove in the upper lip that runs from the top of the lip to the nose) to help lift the upper lip.

The areas enhanced will depend upon your individual features and what we are looking to enhance.

Please don’t worry too much about knowing which dermal filler to choose. 

My initial recommendation would be to seek an injector that uses a reputable brand (Juvederm, Teoxane, Restylane or Belotero) as this will help to ensure safety as well as superior results. 

In all of my clinics I use Juvederm. I have worked with all of the brands mentioned above but find Juvederm to provide the best results. 

Juvederm provides a range of dermal fillers depending on the area treated and the result desired. For the lips I commonly use Juvederm ultra smile, Juvederm 3 and  Juvederm Volbella. 

Following an in-depth consultation, I will explain to you which filler I recommend and why. If there is a choice of more than one filler I will offer them both and explain the benefits of each. Together we can decide which one we feel is best suited to your needs. 

Following the consultation and completing the necessary consent process including pre-treatment photographs, we start cleansing the skin with an antimicrobial agent as it is very important to ensure the area is appropriately disinfected.

We apply a topical anaesthetic – a numbing cream to the lips and then allow you to relax. Once the numbing effect takes place, we begin the treatment. 

I usually start with the top lip then move to the bottom lip and give you a mirror to have a look and see what you think (if you want that is!) I like to leave some product for adjustment so after we have both looked at them we can decide on where we feel slight improvement is needed. 

Often clients ask me how many injection points there is. It is difficult to give an exact amount as everyone’s lips are different and require a tailored approach, but this usually ranges between 10-15 points.

At the end of treatment I apply an anti-bruising cream to the area and discuss all of the aftercare that is important to ensure quick and safe healing!

Modern lip fillers are predominantly made up of hyaluronic acid – a substance that is naturally found in the skin. 

Previously fillers were made of other materials such as collagen but as a result of side effects, it is more common to use hyaluronic acid based temporary fillers as they are much better tolerated and have an increased safety profile.

This depends on each individual and the type and amount of filler used. Typically I would say lip filler lasts between 3-6 months.

As the lips are a delicate area, it’s likely that there may be some discomfort during treatment. 

To make the treatment as comfortable as possible, we apply a numbing cream to the lips prior to treatment. The lip filler itself also contains anaesthetic which also helps to reduce discomfort.

Being a Dentist it would be very easy for me to numb the lips with dental blocks, I choose not to do this for reasons of safety.  Although complications are extremely rare, It is important that I can recognise the signs early on and unfortunately, dental blocks can distort this. 

That being said, clients cope absolutely fine with numbing cream alone.. and of course a gentle injector.

Lip fillers have an excellent safety record, but should always be administered by experienced professionals. It continues to  surprise me when consenting clients prior to treatment, how many of them have not been informed of the risks involved before previously having treatment.

Although hearing the risks can be off putting, I pride myself in full transparency as I believe it is very important for clients to understand all of the risks involved before agreeing to treatment as it is a medical procedure.

An overview of the risks include:

• Overcorrection / under correction & facial asymmetry • Unpredictable persistence of filler, either shorter or longer than expected. • Prolonged discolouration of the skin • Prolonged or severe swelling • Reactivation of cold sores • Infection • Scarring • Ulceration • Granulomas or firm nodules • Allergic or anaphylactic reaction • Blindness  

A remote and extremely rare risk is that of filler injection into a blood vessel, leading to blockage of the vessel. This could result in reduced blood flow to an area of tissue, leading to tissue damage and tissue death (necrosis), which could be seen as skin breakdown, ulceration and scar formation. Blood vessel blockage near the eye can result in blindness.

Please note: these risks are extremely rare and highlight the importance of seeing a highly trained medical professional who is adequately trained not only in administering dermal filler but also dealing with any possible complications.

Getting lip fillers is not bad for you, as long as your visit an medical professional that is appropriately qualified. 

Overfilled lips and a lack of understanding of anatomy can result in poor appearance and also increase the risk of complications related to filler.

With the small amounts of filler I use, over time the filler will naturally breakdown to restore the original appearance of the lips.

When using small amounts of filler, the lips will appear natural. 

I never administer more than 1 ml in one visit. 

You may get some initial swelling that causes the lips to appear larger than they actually are but once this settles you will be left with natural, plumped lips.

I see my clients treatments as my art work, and therefore do not seek to have them look unnatural!

By visiting an experienced Aesthetic Doctor who understands lip anatomy and the importance of less is more. 

Sadly we see a lot of overfilled lips, particularly on social media. This is a result of poor technique, multiple ML’s of filler and an injector that doesn’t understand when it’s best to stop .

My approach to aesthetics is very minimal so it’s highly unlikely that you would look overdone after having lip filler treatment. 

These treatments present a convenient, minimally invasive option that delivers outstanding, natural-looking results.

Although mild bruising can occur immediately following your treatment, this heals quickly – and you’ll start to notice the added volume right away. 

Other side effects are transient and can include: mild pain at the area of treatment, swelling and redness.

Downtime is dependent on the area treated, how much filler is administered and also the individual client’s response to filler. 

Majority of treatments have very little downtime and mild side effects such as redness, swelling and itching only last a few hours. Where bruising may occur, this can take a few more days to settle. 

I would say for lip filler it is wise to allow a few days for the lips to fully settle down. Most clients can return to work and social events immediately after treatment however must follow the recommended aftercare advice.

For the first 24 hours after treatment it is best to avoid:

  • Alcohol
  • Physical strain and sports/exercise
  • Touching the face
  • Make up (including lip balm)
  • Rubbing the face
  • Aspirin/Ibuprofen

For two weeks following treatment it is best to avoid:

  • Saunas
  • Steam rooms
  • Direct sunlight
  • Facials / Chemical Peels / Microdermabrasion
  • IPL/Laser treatments
  • Dental procedures
  • Further Lip Filler Treatment

If you do have any other treatments scheduled, please inform me at your consultation so we can ensure we create a treatment plan that incorporates these treatments to achieve the best results, in a safe manner. 


All Aftercare will be discussed in detail at your appointment.

Alcohol is not recommended for 24 hours after having lip filler treatment. Although it won’t impact the results of the treatment itself, because alcohol can thin the blood and cause the blood vessels to dilate, this can increase the risk of bruising and swelling following treatment and prolong the recovery.

Although other medical injectors may advise smoking is OK, I like to err on the side of caution and my advice would be to avoid smoking for 24 hours after having lip filler treatment. 

This is because I want to there is enough time for the filler to settle and heal adequately and also to help prevent any possible risk of infection.

Most of the swelling settles in the following 24-48 hour after treatment. But it can then take a further 3-4 days for the lips to fully settle.  Although most of the swelling settles within a few days, it can take  up to 4-6 weeks following treatment before the lip filler integrates within the lip and the best results are seen.

The lips may look larger immediately following treatment and this can lead to one of two responses:

1) Being worried that the lips look too big – do not worry, they will reduce in size and settle down!

2)  Feeling that the filler has ‘disappeared’ once the filler settles.  This is not the case as there will be a definite improvement even with small amounts of filler. It is possible that you may need further treatment if you would like a more enhanced result. It’s always good to start small.

Dermal fillers are temporary fillers and have the ability to be dissolved with hyaluronidase (hyalase) an enzyme that can breakdown the hyaluronic acid – the main constituent of filler. Whilst it is possible to dissolve filler, this is usually only reserved for emergency situations where a complication is suspected. 

The reason for this, is that whilst it seems theoretically easy to dissolve filler, there are further risks involved with doing so and therefore a decision to perform this reversal should not be taken lightly.

If you are unhappy with your filler for whatever reason, I recommend returning to the person who administered the filler and discussing the options available. and risks involved.

In special circumstances the filler can be dissolved but this needs to be done with the person who originally provided the filler as they know where they have placed the filler and therefore know where to place the reversal agent.

As the lip fillers integrate within the natural skin tissues, they should not be felt when kissing.

I would avoid kissing for at least 24 hours after treatment – but ideally until the lips have fully settled which can be a few days.
