Micro-needling is an innovative technique that allows the correction of skin blemishes of various kinds, through the stimulation of physiological cell turnover. The technique is frequently combined with the topical use of active ingredients specific to the pathologies treated. During the session, the skin is subjected to multiple micro-perforations, performed using a multi-needle instrument that mounts small sterile steel needles at the top. The micro-trauma, triggering tissue repair mechanisms, stimulates the production of collagen and elastin by fibroblasts, resulting in dermal remodeling of the treated areas.
