A Novel “stroke scheme without spots and gaps” technique: A mechanical innovation to prevent pigment patchiness in eyebrow micropigmentation

PROBLEMAchieving stable and uniform healed results in eyebrow micropigmentation remains a persistent challenge in esthetic practice.Practitioners frequently observe uneven pigment retention, including patchiness and localized pigment voids after healing. [1]ese inconsistencies often necessitate secondary touch-up procedures, which increase cumulative tissue trauma and elevate the risk of inflammation and fibrosis. [1,2]nventional approaches, such as microblading and standard machine-based techniques, rely on linear intradermal pigment implantation. [2]ese methods commonly involve vertical pressure combined with skin stretching, which can result in uncontrolled penetration into the reticular dermis. [3,4]As a consequence, pigment distribution becomes irregular, with excessive depth leading to color distortion and reduced long-term stability. [3]is highlights a fundamental limitation of existing techniques: reliance on operator intuition rather than a structured, reproducible implantation system.To execute this correctly, several technical principles are integrated into a single mechanical protocol.First, the elimination of vertical pressure is crucial; the skin is stabilized without www.cosmoderma.
