1. Fractional Radiofrequency Technology: Secret RF uses fractional radio frequency electromagnetic waves to specifically target the deeper layers of the dermis, typically between 1 and 3.5 mm below the skin's surface. This fractional approach means that only a fraction of the target area is treated at any one time, leaving untreated areas in between. This promotes faster skin recovery. 
2. Sterile needles: Unlike some laser treatments, Secret RF does not use a laser, but rather sterile needles to deliver the radiofrequency. These needles are inserted into the skin to reach the targeted layers, where the heat generated stimulates collagen production.
3. Collagen fibre contraction: When radiofrequency waves reach the deep layers of the dermis, they cause collagen fibres to contract. This thermal contraction stimulates the production of new collagen, helping to improve skin firmness and elasticity. 
4. Versatile applications: Secret RF can be used to treat various areas of the body, including the face, neck, décolleté, hands, arms and other areas prone to sagging skin. 
5. Clinical Benefits: Potential benefits of Secret RF include skin rejuvenation, improved texture, wrinkle reduction and scar reduction. The fractional technique also allows for faster recovery compared to some more invasive treatments. 
6. Number of sessions and results: Usually, several treatment sessions are recommended to achieve optimal results. Results usually become visible progressively over time, with continued improvement in skin texture and firmness.

It is important to consult a qualified professional to determine if Secret RF is the right treatment for your specific needs, and to discuss expectations, potential results and post-treatment care.
