Body contouring and facial definition without surgery: PB Serum lipolytic treatment stands out as one of the most advanced medical enzymatic approaches to localized fat reduction available today. Offered in Geneva and throughout the Swiss Romande region, this injectable treatment targets stubborn fat deposits that resist diet and exercise. Dr Lucas, FMH-certified plastic surgeon in Geneva, combines deep anatomical expertise with surgical precision to ensure both safety and natural-looking results at every session.
What Is PB Serum Lipolytic Treatment?
PB Serum is an injectable enzymatic complex containing three active enzymes: lipase, which breaks down adipocytes in a controlled manner; collagenase, which targets fibrous tissue and improves skin texture; and lyase, which complements the lipolytic action. Together, these enzymes achieve targeted fat cell reduction while secondarily improving skin quality.
Rather than simply “dissolving fat”, the aim is to restore natural, balanced proportions across the face and body. As Kybella® is not authorized by Swissmedic in Switzerland, PB Serum is the leading enzymatic alternative available on the Swiss market distinct from other lipolytic body injection protocols offered at the clinic for other indications.
Treatment Areas
PB Serum adapts to a wide range of localized fat deposits. On the face, it effectively treats the double chin recreating a well-defined cervico-mental angle of approximately 105 to 120° in women, slightly sharper in men as well as the lower face and cheeks. For a full overview of facial treatments available at the clinic, visit our aesthetic medicine of the face page.
For the body, indicated areas include the abdomen, love handles, arms, inner thighs, and bra fat rolls. These treatments are part of our comprehensive body contouring offering in Geneva, which also includes liposuction with Renuvion® and other surgical solutions.
In women, the treatment aims for soft, continuous curves; in men, the result is more angular and structurally defined. Dr Lucas approaches every case with a global understanding of anatomical proportions.
Who Is This Treatment For?
PB Serum lipolytic treatment is designed for women and men with localized fat deposits resistant to diet and exercise, seeking a non-surgical solution. For larger volumes, body liposuction with Renuvion® or abdominoplasty may be considered. For arm or inner thigh refinement, arm and thigh lift surgery is an available alternative. For complex double chin cases, neck liposuction with Renuvion® can complement or replace enzymatic treatment. A consultation with Dr Lucas determines the most appropriate solution for each patient’s profile.
How Does a PB Serum Session Work in Geneva?
Before the Session
Aspirin and anti-inflammatory medication must be stopped 10 days before treatment. Any anticoagulant therapy (Sintrom, Coumadin, Eliquis, etc.) must be disclosed to Dr Lucas. Alcohol should be avoided 48 hours prior, and good hydration is recommended. Contraindications include pregnancy, breastfeeding, active infection, and coagulation disorders.
During the Session
Dr Lucas begins with precise marking of the treatment zones, followed by strict antiseptic preparation. Injections are performed using a fine needle or microcannula, depending on the area and tissue depth, ensuring even distribution of the enzymatic complex. Local anesthesia topical cream or local injection ensures patient comfort. Sessions last approximately 30 minutes. Discomfort is mild to moderate, typically rated 2 to 3 out of 10. No hospitalization is required.
After the Session
Tightness or tenderness may be felt for 48 hours, relieved by paracetamol. Swelling is common for 3 to 5 days; mild bruising may occur. Return to work is possible within 24 to 48 hours, and return to sports within 48 to 72 hours. No sutures are needed. Post-treatment instructions include: ice packs for the first 48 hours, avoiding heat exposure (sauna, steam bath) for 5 days, no intense exercise for 48 hours, avoiding intensive massage unless directed, and maintaining proper hydration. A follow-up with Dr Lucas is scheduled at 4 weeks.
Results, Timeline and Longevity
When Are Results Visible?
Initial changes appear within 2 to 3 weeks of treatment. Optimal results are visible between 6 and 8 weeks, as the body progressively metabolizes and eliminates the fragmented adipocytes.
How Many Sessions Are Required?
Typically 1 to 3 sessions are needed, spaced 3 to 4 weeks apart. The exact number depends on fat layer thickness, the area treated, and the desired outcome. Dr Lucas determines the appropriate protocol including the selection of PBSerum Medium or PBSerum High at the initial consultation.
How Long Do Results Last?
Destroyed adipocytes do not regenerate, making results long-lasting. Provided weight remains stable, the effect is considered permanent for the treated cells. Significant weight gain may cause fat accumulation in other areas, but eliminated cells remain gone permanently.
Side Effects, Risks and Safety in Switzerland
As with any medical injection, adverse effects may occur: prolonged swelling, bruising, infection (rare), irregularities, asymmetry, or excessive inflammatory reaction. These complications are uncommon when treatment is performed by an experienced physician in a compliant medical setting.
In Switzerland, lipolytic injections are classified as medical procedures. Only physicians holding a valid cantonal medical license and professional liability insurance are authorized to perform them. The aesthetic medicine practice of Dr Lucas fully complies with Swiss regulatory requirements and FMH standards. Non-certified products and counterfeits exist on the market and may pose serious health risks. Incorrect injection depth can lead to severe complications including skin necrosis, vascular injury, or permanent irregularities. Anatomical expertise is therefore essential.

FAQ – PB Serum Lipolytic Treatment
How does PB Serum lipolytic treatment work?
PB Serum is an injectable enzymatic complex containing lipase, collagenase, and lyase. These enzymes break down fat cells in a controlled way, reduce fibrous tissue, and secondarily improve skin quality. The action is targeted to localized fat deposits and results develop progressively over several weeks.
What is the difference between PB Serum and liposuction?
Body liposuction with Renuvion® is a surgical procedure for larger fat volumes under anesthesia. PB Serum is a non-surgical outpatient alternative suited to moderate, localized deposits with minimal downtime. Results are progressive. For cases requiring greater volume correction, a surgical consultation can be arranged at the clinic.
Is PB Serum treatment painful?
Discomfort is mild to moderate, typically rated 2 to 3 out of 10 comparable to a standard aesthetic injection. Local anesthesia is applied before the session. Post-treatment tightness or sensitivity fades within 48 hours and is managed with paracetamol.
How many sessions are needed for a double chin?
Generally 1 to 3 sessions spaced 3 to 4 weeks apart. For more complex cases, neck liposuction with Renuvion® may be considered as a complementary or surgical alternative. The 4-week follow-up allows evaluation and protocol adjustment.
What are the risks and side effects of PB Serum treatment?
Typical side effects include swelling for 3 to 5 days and possible mild bruising. Less common complications include prolonged swelling, infection, irregularities, asymmetry, or excessive inflammatory reaction. Treatment must be performed by an experienced physician in a medically compliant setting.
Is PB Serum an alternative to Kybella in Switzerland?
Yes. As Kybella® is not authorized by Swissmedic in Switzerland, PB Serum is the available enzymatic medical alternative for double chin and localized fat reduction. The clinic also offers lipolytic injections for other body areas depending on the indication.
What is the price of PB Serum treatment in Geneva?
Treatment starts from CHF 600 per area, with a 4-week follow-up included. The total cost depends on the number of areas and sessions required. See the full pricing page or book online for a personalized quote.
Are the results permanent?
Destroyed adipocytes do not regenerate, making results long-lasting. Maintaining a stable weight is the primary condition for preserving results. Eliminated fat cells do not return, even if weight gain may cause accumulation elsewhere.
