Scaly skin
Psoriasis. Artwork comparing two sections through human skin: healthy skin (left) and skin affected by psoriasis (right). Psoriasis is the presence of scaly lesions on the skin, caused by an increase in the rate at which new skin cells are produced. Normal skin consists of an epidermal layer of dead skin cells (light grey) that arise from a thin layer of living epidermal cells (dark grey). Below these is the large connective tissue layer of the dermis that also contains blood vessels (bottom). In psoriasis, constant division pushes older cells upwards from the living epidermal layer to flatten and die, forming a thick layer of painful, flaky skin (top)

EDITORS COMMENTS
This print showcases the stark contrast between healthy skin and skin affected by psoriasis. The artwork provides a detailed comparison of two sections through human skin, revealing the detrimental effects of this chronic condition. Psoriasis is characterized by scaly lesions that appear on the skin due to an abnormal increase in the production rate of new skin cells. On the left side of the image, we observe a section of normal, healthy skin. It consists of a thin layer of living epidermal cells (dark grey) from which dead skin cells (light grey) arise. Beneath this lies the dermis, a connective tissue layer housing blood vessels for nourishment. In stark contrast, on the right side, we witness how psoriasis wreaks havoc on one's complexion. Constant cell division pushes older cells upwards from the living epidermal layer to form a thick layer of painful and flaky scales at its surface. This excessive growth disrupts the natural balance and causes discomfort for those affected. Through this monochrome illustration layered with intricate details, Science Photo Library captures both scientific accuracy and artistic beauty simultaneously. This thought-provoking visual representation sheds light on psoriasis as a disorder that affects millions worldwide while emphasizing its impact on overall health and well-being.
