What it is
RF Arm at Klinik Amisi is a non-invasive radiofrequency treatment focused on supporting firmness on the upper arms. It is delivered using the Thuzzle platform from GMV Medical Innovation (Italy), with handpieces and settings tailored for the body. It sits within our body pillar as one of four related RF body protocols — RF Tummy, RF Thigh, RF Buttock and RF Arm.
The treatment is needle-free and uses controlled radiofrequency energy to gently warm the deeper layers of the skin on the upper arms. It is typically chosen by patients with mild to moderate skin laxity, often after weight loss or with age-related changes, who prefer a non-invasive approach over surgery.
A consultation is required before the first session so our doctor can assess the area, your medical history and any prior procedures, and confirm whether RF Arm is appropriate.
How it works
Radiofrequency energy is delivered through a handpiece that glides over the skin in a warmed gel medium. The energy heats the deeper dermal layers in a controlled way, typically warming tissue to around 40 to 45 degrees Celsius. Existing collagen fibres respond with an immediate contraction, which can produce a subtle tightening sensation. The warming also triggers the skin’s natural repair response, encouraging fibroblasts to produce new collagen and elastin over the following weeks and months.
The Thuzzle platform allows the clinician to switch between deeper monopolar and more superficial bipolar modes, and to adjust intensity for your skin and comfort. The temperature is monitored throughout the session.
What to expect
Before your treatment
Your first visit begins with a consultation. We will discuss the area you want to address, medical history, any prior body procedures and any implants. Please come with the area clean and free of heavy moisturisers or oils.
During the session
You will sit or lie comfortably with the upper arms exposed. Warmed coupling gel is applied and the handpiece is moved in continuous passes across the area. A typical session takes 30 to 45 minutes. Most patients describe the sensation as a comfortable, deep warmth.
After your treatment
The skin may feel warm and look slightly pink for a short time. Use a gentle moisturiser, and broad-spectrum sun protection if the area is exposed. Avoid very hot showers, sauna and intense exercise for the rest of the day. You can return to most normal activities straight after the session.
Recovery and downtime
RF Arm typically has minimal downtime. Mild warmth or pinkness usually settles within a few hours, and there are no marks or peeling. Improvement in firmness builds gradually over the months following the course as collagen activity continues, and individual results vary. Maintenance sessions are sometimes suggested afterwards.
Who is this for
RF Arm is typically offered to adults with mild to moderate skin laxity on the upper arms who want a non-invasive supportive treatment, often after weight loss or as part of a broader body contouring plan.
You may be a candidate if you have:
- Mild to moderate skin laxity on the upper arms
- Loose or crepey skin after weight loss
- A preference for non-surgical skin firming
- Realistic expectations — RF supports firmness rather than removing excess skin
- Willingness to commit to a course
- No contraindicating implants or medical conditions
Considerations and contraindications
RF Arm is generally not recommended for patients who are pregnant or breastfeeding, who have a pacemaker, defibrillator, cochlear implant or other implanted electronic medical device, who have a metal implant in the treatment area, or who have active skin infection, open wounds or recent sunburn in the area. Always inform our doctor of any medications, implants, prior surgery and medical history during consultation, so we can confirm whether this treatment is right for you.
