Secret RF — Microneedle Radiofrequency

Secret RF at MarBelle Clinic delivers radiofrequency energy precisely into the dermis using a matrix of gold-plated microneedles — the Ilooda Secret RF system. Unlike traditional surface-heating radiofrequency devices, the needles bypass the epidermis entirely, placing energy at the exact dermal depth where collagen remodelling has the greatest structural impact. The result is improved skin firmness, reduced fine lines and wrinkles, minimised pore size, and smoother texture with minimal surface trauma. Aftercare products are included in every session price, and numbing cream is applied before treatment for comfort.

Microneedle radiofrequency combines two established skin-remodelling mechanisms into a single device: the collagen-induction response triggered by controlled skin puncture, and the deep thermal coagulation produced by radiofrequency current. The Ilooda Secret RF system — used at MarBelle Clinic — is a fractional device that deploys an array of insulated needles to penetrate the dermis to a preset depth, then discharges bipolar radiofrequency energy between the needle tips. Because the needles are insulated except at their tips, the epidermis receives negligible heating; only the dermis at needle depth is treated. This protects surface melanocytes, making the treatment safe across all Fitzpatrick skin types. The radiofrequency energy delivered at the needle tips creates focal zones of thermal coagulation — controlled micro-injuries at the dermal level that trigger the wound-healing cascade. Fibroblasts migrate to these zones and begin producing type I and type III collagen to repair the injury. Over 8–12 weeks as the new collagen matures, the skin becomes progressively firmer, pore walls contract, and the dermal matrix thickens — producing visible reduction in laxity, fine lines, and texture irregularities. The combination with microneedling's own collagen-induction signal means Secret RF produces a synergistic effect beyond either mechanism alone. Clinical data for this class of device shows particular efficacy for: skin laxity (face, neck, décolletage), enlarged pores, mild to moderate rhytids, acne scarring, and post-pregnancy or post-weight-loss skin looseness. At MarBelle, the treatment protocol begins with numbing cream applied 30–45 minutes before the session, reducing discomfort to a mild pressure sensation during needle insertion and a brief warm sensation during RF discharge. The full face and neck treatment takes approximately 30–45 minutes of active treatment time within the 90-minute appointment slot. The fractional pattern of needle placement means approximately 30–40% of the surface is directly treated in each pass, with the untreated bridges accelerating healing. Post-treatment, the skin appears mildly pink and slightly swollen, similar to a moderate sunburn. The aftercare products provided — included in the treatment price — help calm inflammation and support skin barrier recovery. This typically resolves within 24–48 hours, with peeling or mild flaking possible for two to three days. Patients can generally return to normal social activities within three days. For optimal collagen remodelling outcomes, the clinic typically recommends a series of three sessions spaced four to six weeks apart, with maintenance every six to twelve months.
