Microneedling is a process that uses a direct mechanical trauma for tissue modification, i.e. to stimulate the formation of new collagen in the dermis. The microneedling device has a pencil appearance at the end to which there are removable micro-needle extensions, which can be adjusted lengthwise and which cause numerous vertical punctures on the skin at 90 degrees. Such punctures minimally damage the skin’s surface and affect the dermis area where micro-trauma stimulates collagen and elastin formation in fibroblasts, encouraging filling atrophic scars, improving texture of the skin and allowing skin tightening and rejuvenation. In addition, through the micro-channels created by the punctures, it is possible to inject active substances and rejuvenation substances into the deeper layers of the skin, increasing the performance and effect.
Therapeutic indications for the application of microneedling are numerous: acne and operative scars, stretching, hyperpigmentation, hypopigmentation (vitiligo), alopecia, inflammatory dermatitis such as acne and rosary, teleangiectation, rejuvenating procedures, and many others.
