BUTTOCK AUGMENTATION WITH HYALURONIC ACID INJECTIONS

Dernière mise à jour : 16 July 2026

What is buttock augmentation with injections?

Injectable augmentation increases buttock volume and improves shape without surgery. Products sculpt and contour for natural, harmonious results.
Unlike surgery, it requires no recovery, is less risky and is personalised.
Hyaluronic acid, Hyacorp or Sculptra can augment buttocks.
Sculptra® progressively improves contours, projection and firmness without surgery or implants. Unlike hyaluronic acid, Sculptra® is a collagen stimulator made of poly-L-lactic acid (PLLA). It progressively stimulates collagen-producing fibroblasts, naturally increasing volume and improving quality, particularly for discreet results.

Key points

Increasing buttock volume in Geneva

Buttock augmentation with injections is increasingly popular, producing curvier contours without surgery. Products such as Sculptra and Hyacorp, hyaluronic acid designed for the body, naturally and durably improve buttock volume and shape .

Injections reshape the silhouette subtly or substantially according to goals.
Non-surgical augmentation is safe and effective. Curvier buttocks have become fashionable, inspiring magazine titles such as 'buttocks, the new face' or 'Kim Kardashian's buttocks or Jennifer Lopez's'.

Why are my buttocks flat?

Several factors cause flat buttocks.

  • Sex: men tend to have flatter buttocks and women rounder ones.
  • Underdeveloped gluteal muscles.
  • Genetics: fat distribution depends on weight and inherited localisation tendency.
  • Cellulite.
  • Rapid substantial weight loss often causes laxity and less defined contours.

Attractive buttocks

Common aesthetic criteria define harmonious buttocks.
They are toned, rounded and naturally curved.
From behind, an even, defined convex outer curve is seen.
From the side, a clear lower-back transition indicates projection.
Volume ideally concentrates in the upper third for balance.

Buttock shapes

Women have four buttock shapes:

  • Square or H: prominent hip bone or love handles.
  • Round or O: fat in upper and lateral areas creates roundness.
  • Pear or A: fat around lower buttocks and thighs makes the waist appear narrower.
  • Inverted V or V: fat concentrates centrally, with a less full lower part. Typical in older women as oestrogen declines.

Men tend to have flat, square buttocks with upper-half volume. Outer hollows can create a muscular appearance.

How can buttock volume increase quickly?

Hyaluronic acid (Hyacorp) or Sculptra rapidly creates fuller, sculpted buttocks without surgery.
Expert anatomical and injection knowledge is essential to avoid infection or surface irregularities.

Why choose buttock augmentation?

Shape and projection strongly influence silhouette beauty.
They depend on gluteus maximus size and lumbar curvature, the 'lower-back curve'.
Beauty ideals favour full, round buttocks and a defined waist.
Flatness may cause distress and low self-esteem.
Laxity and poor quality can worsen volume-related concerns.

What happens during buttock injections?

Motivations include personal aesthetic goals, fashion or fitness icons.
Adults without contraindications and with realistic expectations are eligible.

Before buttock injections

An initial consultation is essential to:

  • Assess expectations.
  • Explain options and possible results.
  • Explain procedure, preparation and aftercare. Avoid anti-inflammatories and certain supplements for a week beforehand. Dr Romano does not inject patients taking antiplatelets and/or anticoagulants.
  • Exclude contraindications.
  • Select Sculptra or Hyacorp.
  • Analyse shape, areas and volume.
  • Assess amount and prepare a quotation.

Buttock injections

A 15-day reflection period between consultation and injection is a medico-legal requirement.
Stages are:

  • Photographs.
  • Review desired shape and volume.
  • Marking.
  • Comfortable positioning on the examination couch.
  • Cleaning and disinfection.
  • Local anaesthesia for Hyacorp; none for Sculptra.
  • A fine rounded-tip cannula is used.
  • Careful placement in skin and subcutaneous layers.
  • Duration: 10 minutes for Sculptra, between 1 and 2 hours for Hyacorp.

After buttock injections

  • Avoid intense exercise for 24 to 48 hours.
  • Avoid saunas, steam rooms and intense heat for one week.
  • Avoid sitting directly on buttocks for the first 24 to 48 hours.
  • Avoid pressure from clothing.
  • Follow medical aftercare instructions.
  • Gentle massage of injected areas.

Hyacorp injections to increase buttock volume

Hyacorp is preferred for substantial volume.
This highly volumising body hyaluronic acid can be placed throughout, unlike implants in the upper two thirds, allowing outer convexity impossible with implants.
Practice-based local anaesthesia is used.
Dr Romano selects harmonious filling for morphology and anatomy.
A cannula provides safe, even treatment, around one hour.
Immediate usual activities are possible.
Costs are substantial: twenty to thirty syringes may be used.
Absorbable Hyacorp is temporary.
Every year and a half, two thirds of the initial amount need reinjection.

The Sculptra Butt Lift

Sculptra is common in the USA and Brazil, where the Sculptra butt lift is routine.
Collagen stimulation improves quality and contours.
Advantages over Hyacorp include:

  • Improved cellulite.
  • Softer, more toned skin
  • No after-effects.
  • A mild lifting effect.
  • Progressive, natural results.
  • Natural buttock feel, while hyaluronic acid feels firmer.

The drawback is only moderate volume increase.

How do buttock injections differ from implants?

Hyaluronic acid and implants suit different indications and expectations.

Injections are less invasive, non-surgical and require no recovery. Natural, adjustable shape and projection can be modified over sessions, with substantial personalisation, but temporary results need maintenance.

Implants require general-anaesthetic surgery, providing greater volume in one operation and lasting results. Infection, displacement and longer recovery are risks. Shape personalisation is more limited by implant type.

How do buttock injections differ from fat transfer?

Injections and fat transfer are different augmentation techniques.

Fat transfer harvests a patient's fat elsewhere and injects it into buttocks. General anaesthesia, infection and recovery are surgical drawbacks.
Results await swelling resolution. Patients often report temporary results and surface irregularities from uneven absorption.

Injectable products give immediate but temporary volume, requiring maintenance every 12-18 months without recovery or interruption of daily activities.  

Can buttocks be augmented without surgery?

Yes, Sculptra or Hyacorp provide non-surgical augmentation.
Sculptra stimulates progressive, lasting collagen; body-specific Hyacorp gives immediate but shorter-lasting results without surgical constraints.
Personalisation provides natural, harmonious outcomes.

Results before / after buttock injections

Sculptra or Hyacorp injections give visible, natural results.

  • Silhouette enhancement without surgery.
  • Fuller, rounder buttocks with improved shape.
  • Corrected asymmetry.
  • Improved skin imperfections.

Personalised results according to wishes.

How long results last 

Duration depends on product.
Sculptra is progressive, lasting up to two years.
Hyacorp is immediate but temporary, around twelve months.
Lifestyle, metabolism and anatomy also influence duration.
Maintenance every year and a half is expected.

How much do buttock augmentation injections cost in Geneva?

Price depends on Hyacorp or Sculptra and quantity. Hyacorp costs 300 CHF per syringe, generally requiring 20 to 40 syringes according to morphology and goals.
Sculptra costs 900 CHF per vial, usually two to four each session. One to four sessions generally meet volume and consultation goals.
Initial consultation provides a precise quotation.

Buttock injection reviews

Reviews are generally favourable, with high satisfaction for natural results, speed and rapid recovery.
Patients value improved volume, shape and balanced silhouette.
No scars and low complication risk are strengths.

WHAT THE STUDIES SAY
01

In a multicentre study involving 91 patients, injections of hyaluronic acid intended for the body were used to reshape the buttocks. Patients and doctors reported high satisfaction with the volumes and contours achieved. Follow-up included repeated injections: long-term results therefore do not correspond to the effect of a single session.

02

In a study involving thirty women, results of buttock augmentation with hyaluronic acid were followed for one year. Satisfaction was 90% at one month and 62% at twelve months. The gel was gradually absorbed during follow-up. These observations show that volume and contour correction is temporary with the product studied.

03

In a multicentre study involving thirty women, three sessions of poly-L-lactic acid injections were performed to improve buttock contours. Six months after the final session, doctors observed improvement in 84% of patients assessed, and satisfaction reached 96%. Measurements also showed improved skin quality. These results concern the protocol studied, without comparison with a control group.
