Driven by surging demand for minimally invasive aesthetic treatments, semi-permanent makeup and at-home skincare, cosmetic metal steel needles (stainless steel puncture needles), the core consumables for electric microneedling devices and tattoo machines, have achieved rapid market expansion. The whole industrial chain covering domestic manufacturing, cross-border import and export is accelerating standardization. Three major trends including raw material technology upgrading, drug administration classification regulation and standardized customs declaration are reshaping the landscape of the sector. The Yangtze River Delta region including Zhejiang Province has evolved into the core supply base for global cosmetic steel needles.
