DBL™ buttock contouring · Anaesthesia and pre-treatment discussion
DBL™ buttock contouring is an injectable procedure in which hyaluronic acid filler is placed with a cannula through a limited number of entry points. Local anaesthetic is used where appropriate to reduce discomfort at those points and along the planned route. It makes treatment more tolerable, but it is not meant to make every sensation disappear, and some sensations remain important safety signals.
The essential idea
Numbing the entry points does not remove the need to listen to your body. Local anaesthetic reduces discomfort where the cannula enters and moves, but sudden severe pain, skin colour change, breathlessness or feeling unwell during or after buttock filler treatment must be reported immediately. A good pre-treatment discussion explains this before any injection is given.
Where local anaesthetic is used in DBL™
In DBL™, the treatment areas are marked first and the planned approach is explained. Local anaesthetic is then injected at each cannula entry point with a fine needle. Depending on the plan, anaesthetic may also be placed along the route the cannula will follow. Some filler products contain a small amount of local anaesthetic within the product itself, which can add to comfort as the filler is placed.
DBL™ is not performed under general anaesthesia. You remain awake and able to communicate throughout. UK professional bodies have published guidance on buttock augmentation and other body contouring procedures that emphasises medical assessment, appropriate settings and emergency preparedness, reflecting the seriousness of complications in this region.
The NHS explanation of local anaesthetic describes the general principle: it numbs a specific area for a limited time while you stay conscious.
What you may feel during treatment
How treatment feels differs between people and between areas of the buttocks. Commonly described sensations include the following.
Entry points
A brief sting
The small anaesthetic injection may sting for a few seconds before the point becomes numb.
Cannula movement
Pressure and pushing
Movement of the blunt cannula beneath the skin is often felt as pressure, pushing or a dragging sensation.
Product placement
Stretch and fullness
As filler is placed, the area may feel full, tight or stretched, particularly where tissue is firmer.
Positioning
Posture, not the buttocks
Lying face down for a period can cause discomfort in the neck, back or hips. Let the team know if you need to adjust.
Pressure and fullness are expected. Sharp pain at a numbed point may mean the anaesthetic needs topping up. Any pain that is severe, sudden, spreading or unlike the earlier sensations needs a different response, described below.
Why some sensations must still be reported
The gluteal region contains large blood vessels, particularly in deeper layers, and complications involving blood vessels are among the most serious risks of buttock filler. Research describing danger zones of the gluteal anatomy and reviews of minimally invasive buttock augmentation safety explain why product depth and technique matter. Our buttock anatomy article discusses tissue planes in more detail.
Local anaesthetic is used for comfort at access points, not to allow treatment to continue through warning symptoms. If you notice severe or sudden pain, pain that spreads beyond the treated area, a change in skin colour such as pale, dusky or mottled patches, chest pain, shortness of breath, coughing, dizziness or feeling faint, tell the team immediately. Treatment should stop while you are assessed.
Seek urgent help for serious symptoms after you leave
Call emergency services for chest pain, breathlessness, confusion or collapse. Contact the treating team urgently for severe or worsening pain, skin colour change, fever, spreading redness or feeling very unwell after treatment.
What is discussed before treatment
The anaesthetic plan is part of the wider medical assessment. Before treatment, the clinician should ask about, and explain why they need to know, the following.
| Topic | Why it matters |
|---|---|
| Previous reactions to local anaesthetic, including dental anaesthetic | Helps identify allergy or sensitivity and decide on an appropriate approach. |
| Allergies to filler components, antibiotics or other medicines | Some products and aftercare medicines may need to be avoided. |
| Medicines and supplements | Some affect bleeding or interact with anaesthetic. Prescribed medicines should not be stopped without advice. |
| Previous buttock filler, fat transfer, liposuction or implants | Changes tissue planes, anaesthetic spread and treatment planning. Our filler removal planning article explains why product history matters. |
| Heart, liver or kidney conditions; pregnancy or breastfeeding | May affect whether treatment, or a particular anaesthetic approach, is appropriate at this time. |
| Skin infection or inflammation in the area | Treatment through affected skin increases infection risk and is usually postponed. |
| Needle anxiety or a history of fainting | Allows the team to plan positioning, pacing and support. |
Being asked these questions is not a formality. Our article on who may be suitable for DBL™ explains how medical history contributes to the overall decision.
Consent, questions and time to decide
Consent should cover how anaesthesia will be given, what you are likely to feel, what you should report, and what would happen if a complication occurred during treatment. GMC guidance on cosmetic interventions supports giving patients enough information and time to make a decision without pressure.
Useful questions include: Who will be present during the procedure? How will I be monitored? What happens if I feel pain partway through? What emergency equipment and protocols are in place? You can ask to pause or stop treatment at any point, including after anaesthetic has been given.
If any medicines, such as antibiotics, are prescribed as part of your plan, take them exactly as directed and ask about anything you are unsure of.
As the numbness fades
The anaesthetic effect at the entry points usually wears off within a few hours. As it does, you may notice tenderness at the entry points, an ache or tightness in the treated areas, bruising and swelling. Sitting and lying on the buttocks may feel uncomfortable at first. Follow the individual aftercare advice you are given about sitting, activity and pain relief.
Firmness and swelling can make the shape look different during the first weeks, as explained in our DBL™ results article. Tenderness should gradually improve rather than intensify. New or worsening pain, warmth, redness or fever should be reported promptly, as should any lump that becomes painful.
Results vary between patients and cannot be guaranteed. A review or further treatment may be recommended, and any decision about it should follow reassessment once swelling has settled.
Frequently asked questions
Is DBL™ performed under general anaesthesia?
Does the filler itself contain anaesthetic?
Why do I need to report pain if the area is numb?
Can I take painkillers before my appointment?
Why is my previous filler history part of the anaesthesia discussion?
Can I change my mind on the day?
Individual assessment
Discuss anaesthesia, safety and suitability before deciding
A consultation can explain how DBL™ is performed, what you may feel and which symptoms should always be reported. Bring details of any previous buttock treatment.
