The RF energy is delivered through the focused tip of the micro-needles, leading to far-less trauma to the surrounding epidermis. This leads to significantly decreased discomfort and down time for the patient compared to conventional fractional lasers. Non-insulated micro-needles are more effective and takes care of both epidermal and dermal problems without the need for additional superficial fractional RF treatments (SFRs).Insulated needles: equal therapy to epidermis and dermis layer
