Skin is the outermost tissue layer of the body, providing the initial barrier encountered during surgical approaches. It is layered — the epidermal layer at the surface, the dermis layer beneath it, and the subcutis below that — and several builds on this page cut through the whole stack at once, as skin and subcutaneous tissue.
Materials

|---|---|---|---|---|
| Felt | Trocar Placement Trainer, Soft Tissue Lesion Simulator | Felt sheet skin layer | ||

| Animal Skin | Muller Cricothyrotomy Simulator | Section of porcine skin; provides the scalpel incision surface. | ||
| Foam mattress | Man-O-War Chest Tube Simulator | "extra dur" (extra-firm) foam mattress; it stands in for skin and the chest wall together. | ||
| Vinyl | Appendectomy Simulator, Open Appendectomy Simulator (Matthews) | Outer vinyl skin layer — the outermost surface of the abdominal-wall stack.[1] | ||
| Ioban2 antimicrobial drape | Multipurpose Thoracic Simulator (Carter) | Iodophor-impregnated transparent adhesive drape wraps the chest wall module as sealant and outermost traversable layer.[2] | ||
| External skin overlay | Gauger Cricothyroidotomy Trainer | External skin overlay for emergency needle cricothyroidotomy training. | ||
| Fabric | Cricothyrotomy Simulator (Aho) | Outermost layer wrapping the model. Provides cuttable surface. | ||
| Synthetic skin | Peripheral Intravenous Catheterization Trainer, Bronchoscopy-Guided Percutaneous Dilatational Tracheostomy Simulator (Kattan), Pediatric Front-of-Neck Access Simulator (Kovatch) | As tattoo practice skin: the puncture surface (epidermis). As a commercial 3-layered flat pad, allowing about 9 iterations per pad.[3] As a commercial elastomer shaped overlay: the outer neck skin.[4] | ||
| Liquid plastisol | Emergency Department Thoracotomy Simulator (Misra) | Medium-density liquid plastisol with skin-tone pigment. Paired skin/fat sheets are designed for one-use-per-resident replacement.[5] | ||
| Goat or lamb hind leg (skin layer) | Hemorrhage Control Simulator (Malik) | Outer surface of partially defrosted hind leg. | ||
| Synthetic silicone rubber overlay | Thoracoscopic Diaphragmatic Hernia Repair Simulator (Barsness) | Replaceable silicone skin overlay; it is the consumable part, swapped between trainees.[6] | ||
| Silicone cast over power mesh fabric | Pediatric Inguinal Hernia Repair Simulator (Heo) | Mesh-backed silicone skin sheet | ||
| EVA Foam | - | - | Synthetic Tourniquet Training Model (Souza Lima) | EVA sheet skin layer |
| Elastomeric impression material (light or medium body) | - | - | Suturing Simulator (Kumaresan) | A thin layer of elastomeric impression material forms the skin face; its rubbery texture and tear strength give acceptable resistance to a suture needle.[7] |
| Vinyl doll | - | - | Abdominal Wall Defect Simulator (Medeiros) | Vinyl baby doll body, giving the neonatal torso shape and the umbilical landmark.[8] |
| EVA Foam + Sponge | Intra-abdominal Bleeding Simulator (Fernandes) | EVA-foam plate over a thin sponge layer as the skin and subcutaneous incision surface.[9] | ||
| Acetic silicone + maize starch | - | - | Suture Simulator (Almeida) | Moldable silicone-and-starch suture pad. A single homogeneous layer — a suturable skin-like surface that does not reproduce the different layers of skin tissue.[10] |
| Pomelo peel (Citrus Maxima) | - | - | Skin Graft Harvesting Simulator (Cohen) | The fruit's tri-layered pericarp — exocarp, mesocarp and endocarp — mimics human integument, giving tissue-plane differentiation.[11] |
| Castable silicone + Soma Foama 15 | – | – | Chest Tube Insertion Simulator (Brannan) | Three-layer cast-silicone laminate: the top skin layer is Ecoflex 00-30, the middle is the expanding silicone foam Soma Foama 15, and the innermost layer is Dragon Skin 10.[12] |
| Polyurethane Foam | - | - | Percutaneous Renal Access Simulator (Ewald) | Premium Poly Foam. Layers of thick, visually opaque foam encase the gelatin block, giving the resistance and the visual obstruction that simulate overlying skin, fat and muscle.[13] |
| Gelatin | - | - | Resuscitative Endovascular Balloon Occlusion of the Aorta Simulator (Keller) | Ultrasound-compatible gelatin block simulating combined groin soft tissue (skin, fat and muscle) |
| Foam, soft | - | - | Lumbar Laminectomy and Dural Closure Simulator (Bakhshi) | |
| Coated Fabric | - | - | Lumbar Laminectomy and Dural Closure Simulator (Bakhshi) | As rexine covering the book-fold foam block; the trainee enters through a pre-cut slit rather than incising the cover. |
| Polyurethane Foam (headliner foam) | - | - | Multipurpose Thoracic Simulator (Carter) | Foam chest-wall covering[2] |
| Grapefruit rind and pith | Grapefruit Distal Anterior Cerebral Artery Bypass Simulator | Skin analogue[14] | ||
| Castable silicone with power mesh fabric | Adult Proximal Tibia Intraosseous Access Simulator (maxSIMIO) | Dragon Skin 10 NV with skin-coloured Silc-Pig pigment; power mesh fabric embedded for skin strength. Version one of the simulator.[15] | ||
| Castable silicone, power mesh (80% nylon/20% spandex) | Melanoma Excision Simulator (maxSIMhealth), Z-Plasty Simulator (maxSIMhealth) | Melanoma Excision Simulator (maxSIMhealth): Ecoflex 00-20 FAST. Power mesh between silicone layers for durability. Pigmented with Silc Pig (various skin tones). Z-Plasty Simulator (maxSIMhealth): Ecoflex 00-20 FAST. Carries a small scar marking the incision site. Power mesh between the skin layers, in the incision areas, for durability. Pigmented with Silc Pig (skin tone; scar coloured red).[16] | ||
| Clear packing tape | Soft Tissue Lesion Simulator | Over the felt. It gives a firm surface for the incision and holds the layers together, which increased the durability of the model.[17] | ||
| Sponge | Soft Tissue Lesion Simulator | A large sponge. The source says the sponge represents "wounded skin and tissue". The wound model has no felt, tape or gelatin: the sponge is both the surface and the depth.[17] |
