Show HN: I'm a dermatologist and I vibe coded a 3D biophysical skin model

- TCA CROSS uses 70% trichloroacetic acid applied directly to pitted scars to coagulate protein, which is replaced by new collagen over weeks, lifting the scar floor.
- Fractional laser settings (30 mJ, 200 zones/cm²) create microcolumns of coagulated tissue that remodel scars over months, with depth and width varying by energy level.
- Acne scars can be simulated as ice pick, boxcar, or rolling types, placed in clusters, with severity and mix adjustable via sliders.
- The skin model includes anisotropic pretension, anisotropic moduli (skin 30 kPa, fat 10 kPa, scar 120 kPa), and overdamped viscoelastic response to simulate realistic tissue deformation.
