Skin needling is a minimally invasive dermatological procedure that creates controlled micro-injuries in the skin using fine sterile needles mounted on a specialized device, stimulating natural collagen and elastin production through the wound healing cascade. The procedure penetrates the stratum corneum to precise depths between 0.5 and 2.5 millimeters.
The mechanical trauma induced by microneedles triggers the release of growth factors and cytokines, initiating neovascularization and neocollagenesis. This process activates dermal fibroblasts, promoting the synthesis of type I and III collagen, essential structural proteins for skin regeneration and remodeling.
The technique demonstrates efficacy in treating various dermatological conditions, including acne scarring, photoaging, hyperpigmentation, and striae distensae. The microchannels created during treatment enhance transdermal drug delivery, increasing the bioavailability of topically applied substances by up to 500%. Clinical studies show optimal results through treatments spaced 4-6 weeks apart, with visible improvements in skin texture, firmness, and overall appearance.
