Microneedle Machine Rf MFR SFR Microneedle Fractional Machine Intracel Rf Micro Needling SFR Collagen Induction Therapy Unique dual channels of SFR noninvasively delivers RF energy to the Epidermis and superfical dermis with synergistic effect,resulting in luminous skin and controlled tightening. Wound Healing Mechanisms by RF energy Since Micro-needles are insulated except the edge part (0.3mm), Micro-needle electrodes deliver bipolar energy directly deep into dermis without damage in epidermis.   Minimally invasive RF thermal energy creates fractional electrocoagulation in dermis which facilitate natural Wound Healing Process. WHM promote the remodeling of collagen and wound contraction, which enhance skin laxity. Not only stimulate dermal remodeling but also RF inhibit sebaceous gland activity to improve acne. Improved Outcomes Fractional rf microneedle consistent, even thermal distribution ensures more consistent results and improved outcomes. Microneedle tracks and thermal distribution of RF energy in the skin phantom model for the 3 mm depth with different exposure times as shown (in seconds). Images were captured immediately after withdrawal of the microneedles.
