The term "skin conditions" refers to any medical issue that affects the skin, hair or nails. These can range from mild and temporary (such as acne) to chronic and severe (such as psoriasis). Skin conditions are often caused by a combination of genetic and environmental factors, and they can have a significant impact on an individual's quality of life. Treatment for skin conditions may involve medication, lifestyle changes or medical procedures, depending on the severity and nature of the condition.
