Does RF Microneedling Work on Arms, Knees, and Abdomen?

What is Microneedling with Radiofrequency? How Does It Work?

Before we talk about Microneedling with RF for Body, let's discuss the treatment in general. Microneedling and Radiofrequency combine two modalities to repair and rejuvenate the skin.


A Microneedling device holds a network of super fine twenty-five gold needles. Going deep into the skin, they make controlled micro-injury. Injuries spark the body's healing response, producing collagen and elastin. Peptide solutions under the needles help the skin heal, producing more collagen.


Radiofrequency delivers heat to the deeper layers of the skin, causing significant collagen and elastin production and growing microcirculation deep into the skin.

Scarlet RF microneedling VS Morpheus 8

Both systems are the most famous as Fractional microneedling RF systems, showing similar results. The most significant difference between the system is isolated and non-isolated needles.

Scarlet RF microneedling has isolated needles, whereas Morpheus8 doesn't. Scarlet creates heat around every isolated needle and has a maximum concentration on the tip, leaving the spaces between insertions intact. Morpheus8 needles are not sole and work simultaneously. They deliver the heat, shooting more extensive areas, not having untouched regions between them.

To understand the difference between these two: isolated and non-isolated, I would give the example of laser evolution. Ablative lasers were pioneers in the market. They perfectly evaporated significant skin areas, delivering the results of skin rejuvenation. The only disadvantage was the side effects: redness for six months, scars, and post-traumatic hyperpigmentation. Because of these side effects, they were replaced with fractional lasers, resembling pixel photo cameras. New laser generation leaves intact areas between the damaged zones, speeding up the healing without side effects.  

The difference in the result is not visible, but the differences mentioned above affect the downtime, pain level, healing speed, and marks, especially on the body. Morpheus's treatment is more painful because of the heat shock. It requires longer recovery, officially mentioned 24 hours, with redness, swelling, and pain. Post-traumatic hyperpigmentation is one of the Morpheus side effects other manufacturers prefer to avoid. Scarlet is not as painful as Morpheus; there are only 3 hours of downtime compared to Morpheus8, and Scarlet never leaves dots on the body skin.

RF Microneedling for Skin Tightening

Microneedling with RF  is famous for skin-tightening body results targeting collagen and elastin at the deep dermis level of the skin. Collagen is responsible for skin structure. It works in tandem with elastin, which helps the skin bounce back after contracting or stretching out. RF destroys cross-linked collagen, called" old collagen," and triggers cells, named fibroblasts, to produce a new one, properly structured. RF, as a technology, burns out "old elastin" tissue without any risks because the same fibroblasts create new elastin fibers. Both of them, collagen and elastin, support the skin and gives it a sturdy structure. Microneedling with Radiofrequency makes you look younger by restoring the face and body's sagging skin and removing wrinkles by sparking the natural production of collagen and elastin.

RF Microneedling for Stretch Marks

A similar collagen and elastin repair process with Microneedling RF is used to treat stretch marks. From the view of skin physiology, stretch marks are a problem with collagen and elastin. When the skin stretches beyond its capacity, like a balloon, it strains the supportive collagen and elastin tissues. Tears result from a lack of skin resistance, and the body struggles to heal the tears. Summarizing the stretch mark occurs because of collagen and elastin weakness. Microneedling RF destroys damaged areas, stimulating damaged collagen and the elastic regions to be replaced with healthier structures. By promoting collagen and elastin production, Microneedling with radiofrequency diminishes stretch mark visibility by improving the skin's thickness and elasticity. Improving the microcirculation in the area helps the skin change from grey to natural pinky. 

RF Microneedling for Scars

Scarring occurs when the wound-healing process has gone awry. When this happens, one of two things occurs. In the first scenario, insufficient collagen production results in skin indentation. In the second, the body creates a lump of tough fibrous tissue, resulting in a bumpy surface on the skin. By boosting collagen and elastin production, Microneedling with Radiofrequency creates new and fresh tissue. As a result, healthy tissue will either fill in the indentation or replace the scar tissue. Either way, the goal is to achieve a smoother and more even surface.

What are Areas of the Body Benefit?

Microneedling with RF shows the best results on the body:


  • Arms
  • Knees
  • Stomach / Belly / Love Handles
  • Thigh area or inner thighs

At MedVSpa, we always look for the best resultative, newest treatments and devices presented on the global aesthetic market. Our Scarlet/ Sylfirm Microneedling RF energy device makes no exception. Scarlet features treatment options for face and body and profound dermal skin remodeling, explicitly designed to address the client's exact needs as sageness is. It features insulated gold-plated needles for precise placement of energy on the depth of collagen with the goal of new collagen and elastin growth.

Radiofrequency RF microneedling for body

We are familiar with radiofrequency microneedling RF's amazing effects on the face. MedVSpa offers the procedure on the body where sagging skin shows. Areas like the knee, abdomen, and arms need a collagen boost, particularly for clients concerned about stretch marks and saggy skin. We successfully treated cellulite, reduced sizes, and removed swelling, but were barely successful in treating sagging skin on the areas like upper arms, elbows, abdomen, and knees before RF microneedling technology appeared on the market. RF microneedling on these areas stimulates collagen and drives peptides containing ingredients deeper to get rid of crepey skin. RF microneedling is an additional technology complimenting Starvac lymphatic drainage for cellulite reduction as it increases the blood flow in the area of concern.

Microneedling RF for dark spots on the body

MedVSpa has the experience of dark spot removal on extensive body areas, like the chest and back. The improvement appears gradually, showing 35%-50% after the first treatment.

Suppose you have hyper-pigmentation from sun damage or as a side effect of tissue damage, called post-traumatic hyperpigmentation. In that case, radio frequency RF microneedling on your chest can significantly help to make the skin tone even and change the texture of your skin. It can also help with those lines appearing as a result of sleeping on your side or your push-up bra.


RF microneedling is a safe, effective anti-aging treatment for arms, elbows, and abdomen. It significantly reduces the appearance of scars and makes the skin look smooth and even. You enjoy the plumpness of your skin even after the first RF microneedling treatment.
