Why does your skin ‘dent in’ when wearing e.g. a too tight wrist band or bra strap or rubber band?

Question

Answer 1

The outside of your skin is dead skin cells known as keratin. Beneath them are skin cells, fascia, muscle, and fat. All human cells are enveloped by a membrane, essentially, the skin of the cell. Each cell is mostly water. The cell membrane is flexible, so it conforms to the pressure around it. When outside influence is present, you might see your body temporarily change shape, because thousands if not millions of cell ~~walls~~ membranes have adapted to the pressure instead of rupturing all over the place
