Radiofrequency microneedling has become one of the most in-demand skin treatments of recent years, and for good reason. It addresses a wide range of concerns with minimal downtime, suits most skin types, and produces results that improve progressively over weeks. Secret RF is the specific device we use at Skin Medical, and it combines precision microneedling with targeted radiofrequency energy to remodel collagen at depth. This article explains how it works, what it treats, what to expect from treatment, and how it compares to other skin tightening options.
Conventional microneedling creates controlled micro-injuries in the skin that stimulate collagen production as the skin repairs itself. Secret RF takes this a step further by delivering radiofrequency energy through the tips of insulated needles at a precisely controlled depth within the dermis. The insulation means the energy bypasses the epidermis and is deposited exactly where collagen remodelling is needed, significantly improving safety across skin types.
The radiofrequency energy heats the dermis, causing immediate contraction of existing collagen fibres and triggering the production of new collagen and elastin over the weeks following treatment. The result is a gradual, cumulative improvement in skin quality and firmness that continues to develop for up to three months after a course of treatment is complete.
Secret RF is effective across a range of concerns, often in combination within the same patient.
Skin laxity and mild to moderate sagging
By remodelling collagen at depth, Secret RF produces a tightening effect that is particularly noticeable in the lower face, jowl area, neck and body. It is well suited to patients with early skin laxity who want to tighten and firm without surgery.
Acne scarring
RF microneedling is one of the most clinically supported treatments for atrophic (depressed) acne scarring. The combination of physical micro-injury and radiofrequency heating at depth remodels the fibrous tissue responsible for rolling, boxcar and ice-pick scars, gradually improving both the depth and texture of scarring over a course of sessions.
Enlarged pores
Patients with visibly enlarged pores see consistent improvement after a course of Secret RF. The collagen remodelling process tightens the surrounding skin structure, reducing the appearance of pore size over time.
Fine lines and surface texture
Secret RF improves the overall surface quality of the skin, reducing fine lines, roughness and uneven texture. Patients frequently notice a smoothing and brightening effect across the treated area as collagen density increases.
Stretch marks
The same collagen remodelling mechanism that addresses acne scarring can also improve the appearance of stretch marks on the body, including the abdomen, thighs and upper arms.
A topical anaesthetic cream is applied to the treatment area for approximately 45 minutes before the procedure to ensure comfort. The Secret RF handpiece is then passed over the skin in a systematic grid pattern. Patients typically describe a warm, prickling sensation during treatment rather than significant pain.
Treatment time varies depending on the area covered: a full face typically takes 30 to 45 minutes. The procedure can be extended to include the neck, decolletage or body areas as needed.
Redness, mild swelling and a sandpaper-like texture to the skin are normal in the 24 to 72 hours following treatment. Most patients are comfortable returning to their usual activities within two to three days. Full skincare routines, including active ingredients such as retinoids and acids, should be paused for seven days. SPF is essential throughout the recovery period and beyond.
Aftercare is an important part of the treatment process, and our clinic provides detailed post-treatment guidance. If you have already been searching for aftercare information before your treatment, the aftercare page at skinmedical.com covers everything you need in full.
Most concerns are addressed over two to three sessions spaced four to six weeks apart. Acne scarring typically requires three sessions and benefits from longer spacing to allow full collagen remodelling between appointments. Skin laxity may show meaningful improvement after two sessions. A single session is not usually sufficient to produce the changes most patients are looking for, and results continue to improve in the weeks following each treatment.
At Skin Medical, we offer a range of skin tightening and quality treatments. Secret RF sits within a broader toolkit alongside collagen stimulators, skin boosters and energy-based devices.
For patients whose primary concern is skin laxity, collagen stimulators such as Sculptra or Ellanse address structural volume loss that RF microneedling cannot target. For patients with diffuse skin quality concerns such as sallowness or dehydration, skin boosters and Profhilo are better suited. Secret RF is most effective where the primary concern is textural change, scarring, open pores or early laxity in a patient with reasonable skin quality.
A consultation will determine whether Secret RF is the most appropriate first treatment for your concern, whether it should be combined with other approaches, or whether a different starting point is more suitable.
Secret RF’s insulated needle technology makes it safer across a broader range of skin types than many other energy-based treatments. In particular, it is suitable for darker skin types (Fitzpatrick IV-VI) that carry a higher risk of post-inflammatory hyperpigmentation with surface-energy devices. Your clinician will assess your skin type and any relevant history before confirming suitability.

Results continue to develop for up to three months after a course of treatment and are typically maintained for 12 to 18 months. Periodic maintenance sessions help sustain the improvement over time.
Yes. Secret RF can be used to treat areas beyond the face and neck, including the abdomen, thighs and upper arms. It is particularly effective for stretch marks and skin laxity on the body.
