“Fractional” devices enable RF energy to be used for controlled fractional skin rejuvenation, and can achieve results similar to fractional laser systems without the risk of pigmentary changes resulting from absorption of energy by epidermal melanocytes.
Because only a fraction of the skin surface is treated at any single time, small “micro-wounds” in the epidermis result which trigger the skin’s natural wound healing response while leaving the untreated zones “between the dots” to serve as a reservoir of healthy cells for faster wound healing and less risk of side effects. When the optional D-pin array is utilized the patient receives the “double benefit” incident to the mechanical skin puncture whereby the skin’s natural wound healing response triggers the release of growth factors from fibroblasts, keratinocytes and monocytes to stimulate the formation of new collagen, elastin and hyaluronic acid for younger, healthier skin.
