Radiofrequency microneedling: what it is and why patients choose it for skin rejuvenation
In the pursuit of healthier, more youthful-looking skin, many patients are turning to radiofrequency microneedling as a non-surgical solution. This advanced treatment combines two well-established technologies—microneedling and radiofrequency energy—to stimulate natural skin repair processes and collagen production. With minimal downtime and a strong safety profile, this procedure is increasingly popular among those seeking visible yet natural skin improvements. In this article, a consultant dermatologist explains how radiofrequency microneedling works and its benefits.
Understanding microneedling and its use in dermatology
Microneedling involves the use of fine needles to create controlled micro-injuries in the skin. These tiny punctures trigger the body’s natural wound-healing response, leading to increased collagen and elastin production, which are the proteins responsible for skin firmness and elasticity.
This technique has been used effectively for years to treat fine lines, acne scarring, enlarged pores, and uneven skin tone. It also helps to improve overall skin texture and resilience, making it a valuable tool in anti-ageing and dermatological care.
What is radiofrequency microneedling?
Radiofrequency microneedling enhances traditional microneedling by delivering radiofrequency energy deep into the skin via the needles themselves. The radiofrequency energy heats the underlying dermis, further stimulating collagen remodelling and skin tightening, without causing significant damage to the skin’s surface.
This combination allows for greater precision and customisation, making the treatment suitable for a wider range of skin concerns. Patients often see firmer, smoother, and more radiant skin over the course of several sessions.
Is radiofrequency microneedling safe, and who is it suitable for?
RF microneedling is generally considered a safe and well-tolerated treatment when performed by a trained professional. Because it works within the deeper layers of skin, it tends to be less abrasive than certain laser treatments, making it an appealing option for patients with darker skin tones who may be at higher risk of pigmentation issues.
Suitable candidates include individuals with:
- Mild to moderate skin sagginess
- Fine lines and wrinkles
- Acne scars or surgical scars
- Enlarged pores
- Uneven skin tone or texture
However, it is not advised for those with active skin infections, severe acne, or certain medical conditions. A detailed consultation is essential to assess suitability and ensure optimal results.
Where can it be applied?
RF microneedling is most commonly used on the face and neck, but it can also be applied to other areas of the body, including:
- Chest
- Abdomen
- Thighs
- Arms
- Hands
These areas may benefit from improved texture and tone, particularly where there is loose or baggy skin, stretch marks, or signs of ageing.
What to expect during a treatment session
A typical radiofrequency microneedling session begins with the application of a topical anaesthetic to reduce discomfort. Once the skin is numbed, a handheld device is passed over the treatment area. The device’s microneedles penetrate the skin at precise depths, while simultaneously delivering controlled radiofrequency energy.
The entire procedure usually takes 30 to 60 minutes, depending on the size of the area being treated. Most patients describe the sensation as mild pressure or warmth, rather than pain.
Following the session, there may be some redness, swelling, or a sunburn-like feeling for a day or two. Most individuals return to their normal activities within 24 to 48 hours, although it’s important to follow post-treatment care guidelines to support healing.
Results are generally progressive, with visible improvement in skin tone and texture over the following weeks. A course of treatments — usually three to six sessions spaced several weeks apart — is typically recommended for optimal results.
