RF microneedling, also known as radiofrequency microneedling, is a cosmetic procedure that uses tiny needles to create micro-channels in the skin and deliver radiofrequency energy to the deeper layers of the skin.
RF microneedling combines radiofrequency technology with microneedles. Unlike other acne scar treatments that addresses the surface of the skin, microneedling uses flow needle technology to deliver radiofrequency waves directly into the dermis where the scar tissues are located. The radiofrequency waves are administered directly into the dermis to encourage collagen production and tissue tightening at predetermined depths decided by the doctor, with minimal downtime. A wide range of atrophic scars can be treated by adjusting the depth of the microneedles, penetrating the skin between 0.5 and 3.5mm.
RF microneedling can be used to address a range of skin concerns, including wrinkles, fine lines, acne scars, uneven skin tone, and texture.
After the treatment, the skin may be red and sensitive for a few hours to a few days, depending on the depth of the needles used. It’s important to avoid sun exposure and to follow any other specific instructions provided by our doctors to help the skin heal properly.
This treatment is almost painless. Some patients have described the treatment as feeling warm and slightly prickly. During the treatment, some ‘firecracker sound’ is heard as the carbon particles interact and absorb the light produced by the laser. You may experience mild redness immediately after the treatment but it should subside in a few hours.
The answer depends on the severity of your scars and your desired results. For mild to moderate scars, you may only need 3-6 sessions spaced 4-6 weeks apart. For more severe scars, you may need up to 12 sessions.
Fibrous scar tissue is often found in the deeper layers of the skin such as the dermis. Most doctors only use CO2 skin resurfacing lasers to reduce the appearance of scars. However, the depth of the micro-channels induced by CO2 lasers is about 1.8mm. This is insufficient to target stubborn, deeper acne scar tissue. RF microneedling on the other hand uses needles that can penetrate up to 3.55mm of the dermis. It’s an effective treatment for various skin concerns and severe acne scars, as it is less invasive, requires a shorter downtime, and results in minimal side effects. For people with ice pick scars, doctors may use other specialty scar treatment such as TCA cross to release the deep scar tissue first. After a few sessions, the overall skin texture can be further improved with RF Microneedling to smoothen out the appearance of residual scars.
