RF Expert (Radiage) – Fractional, Monopolar, Bipolar & Multipolar Radiofrequency

The course offers a comprehensive, advanced approach to radiofrequency (RF) technologies used to treat the skin and subcutaneous tissue of the face and body.

The programme focuses on the differences between monopolar, bipolar and multipolar systems and their modern variants (including microneedling RF and fractional systems), taking into account their physical, biological and clinical properties.

RF technologies work by generating controlled heat in tissue (usually 40–45°C in the dermis), leading to denaturation of collagen fibres and induction of neocollagenesis and neoelastogenesis. Histological studies have shown increased expression of type I and III collagen and remodelling of the extracellular matrix after a series of RF treatments, which translates into improved skin firmness and elasticity.

A key element of the course is understanding the differences between systems:

• Monopolar RF – deep penetration (down to subcutaneous tissue), larger heating volume, effective for lifting and reducing laxity
• Bipolar RF – more superficial action, greater energy control, improves skin quality and wrinkles
• Multipolar RF – even energy distribution, greater safety and comfort, often used in combination therapies
• Microneedling RF (fractional RF) – delivers energy directly to the dermis, strong collagen stimulation with limited effect on the epidermis, used for scars, pores and laxity

RF works differently from lasers – the energy is not absorbed by chromophores (e.g. melanin), which makes RF a safer option for different skin phototypes.

Course programme (advanced)

• combined systems: RF + light (ELOS), RF + ultrasound

3. Procedural anatomy

• layered structure of the skin and subcutaneous tissue
• fibrous septa and their role in cellulite
• fat distribution
• danger zones (e.g. periorbital area, anterior neck)

4. Treatment protocols – face

• skin lifting and tightening
• improving facial contour

• eye-area therapy
• microneedling RF for scars

5. Treatment protocols – body

• firming the skin of the abdomen, arms and thighs

• number of sessions and intervals between treatments
• protocols for individual needs and indications

7. Safety and complications

• overheating and risk of burns
• PIH – less common than with lasers, but possible
• safety procedures

Combination therapies – an evidence-based approach

Research shows that RF achieves the best results in combination therapies when properly combined with other technologies such as HIFU, cryotherapy, laser therapy and electrotherapy.
