Insulated Microneedles for Safer Treatments

MeliaRF features fully insulated microneedles that emit radiofrequency energy exclusively from the needle tip. By delivering heat only to the lower dermal layers, the epidermis remains protected throughout the treatment — a critical advantage for patient safety and comfort.

This insulation design makes MeliaRF particularly well-suited for individuals with darker skin types (Fitzpatrick Scale IV–VI), who face a higher risk of post-inflammatory hyperpigmentation with conventional RF microneedling devices. By shielding the epidermis from thermal energy, MeliaRF significantly reduces that risk.

Optimal & Uniform Thermolysis

MeliaRF achieves optimal and uniform thermolysis through the precise spacing of its microneedles. The ideal inter-needle distance allows bipolar RF energy to be applied uniformly across the target area, ensuring every zone receives consistent thermal stimulation.

This engineered spacing eliminates the risk of energy interference caused by overlapping RF fields in already-treated areas — a common limitation of devices with poorly spaced needle arrays. The result is a more controlled, predictable treatment outcome with fewer hot spots and more even collagen remodeling.

• Uniform bipolar RF energy across the entire treatment zone
• No energy overlap or interference in treated areas
• Consistent thermal stimulation for predictable collagen remodeling
• Reduced risk of uneven results or localized over-treatment
