👉 Blench, also known as a blemish or scaly skin condition, is characterized by the appearance of small bumps or patches on the skin that are often itchy and red. These lesions can appear anywhere on the body, but they are most commonly found on the face, neck, back, and hands. Blench can be caused by various factors such as genetics, environmental factors, stress, and certain medications. The condition is often self-limiting and does not require medical attention.
