ABSTRACT Recently, trends in aesthetic medicine have returned to easy-to- perform, effective and low-cost procedures. Electrical microneedling is one of these techniques. This article discusses the development of microneedling, its mechanism of action, and therapeutic role in the treatment of scars and ageing skin. Microneedling involves the production of thousands of controlled microscopic needle incisions in the papillary and reticular dermis. Using specially designed and manufactured sterile medical devices, the goal is to provide a physical mechanical stimulation of the dermis, while leaving the epidermis intact. This stimulates a wo=und healing repair and regeneration mechanism that results in dermal regeneration, normalised ‘basket weave’ collagen formation, and increased angiogenesis. Clinical studies have provided an objective evidence base for the efficacy and safety profile of the procedure with regard to acne scars, and texture, tone, line, wrinkle and laxity improvement in ageing and photodamaged skin. However, patient discomfort and the inflexibility of most manual skin-needling devices can be limiting factors for the intensity of the treatment and therefore, clinical outcomes achieved. This is where electrical microneedling devices come into their own, as they provide an increased level of intensity, control and comfort. The effectiveness and excellent safety profile of electrical microneedling treatments have resulted in the technique rapidly becoming established in Europe and Asia as a frontline medical aesthetic treatment for scar treatment and skin rejuvenation.
