The Skin Layers Anatomy Model is a 3D cross-section teaching aid showing the structure of human skin — epidermis, dermis, subcutaneous layer, and embedded structures including hair follicles, sebaceous glands, sweat glands, and capillary networks.
For PMU and cosmetic tattoo practitioners, understanding which skin layer a needle is depositing pigment into is foundational to every technique decision. The model gives students and educators a tangible reference for explaining needle depth, pigment retention, healing response, and why certain techniques work on some skin types but not others.
