# The Optics of Human Skin

## One-sentence takeaway

Anderson/Parrish 1981: the dermatology paper graphics skin models all cite for epidermis/dermis optics.

## Problem

Predecessor chain tissue optics. This paper's job: Anderson/Parrish 1981: the dermatology paper graphics skin models all cite for epidermis/dermis optics.

## Design

Anderson/Parrish 1981: the dermatology paper graphics skin models all cite for epidermis/dermis optics. Lineage: tissue optics.

## Evidence

Journal of Investigative Dermatology 1981. DOI `10.1111/1523-1747.ep12479191`. Anderson/Parrish 1981: the dermatology paper graphics skin models all cite for epidermis/dermis optics.

## Limitations

Read the cited predecessors before treating this as a drop-in Anoptic shader. Do not claim the library already implements it.

## Implications for Broadside

Anoptic has a forward+ mesh renderer and is betting on FMM+RC 3D GI. Skin is the first character-appearance hole: translucent dermis, not another BRDF lobe. Do not claim Anoptic already has SSS.

## Bottom line

Mint this 1981 Journal of Investigative Dermatology paper. Anderson/Parrish 1981: the dermatology paper graphics skin models all cite for epidermis/dermis optics.
