Pulled from the live Phoilex store, 2026-11-05. All 20 files are 3024x4032 and all 20 are distinct (md5 checked, no duplicates). Ranked by how readable the change is at ad size.
forehead / temple

a clearly scaling, flaking patch before, clean skin after. The most obviously readable of the set.
elbow

thickened, bumpy, angry patch before, flat and only faintly pink after. Reads at thumbnail size.
inner elbow

red patch before, clear after. Clean and easy to read.
palm / base of thumb

red patch before, clear after.
nape of neck

redness before, clear after. Necklace and top change between the two shots.
neck / jaw

redness before, calmer after. Shirt changes from white to black.
inner forearm

discoloured patch before, more even after.
fingers

mild redness, and the difference is small at ad size.
back of hand

faint marks before, slightly clearer after.
palm / fingers

the two frames look close to identical to me, and I would not ship this one.
