A farmer’s tan is a type of hyperpigmentation that occurs when the skin is exposed to ultraviolet (UV) radiation from the sun. It is characterized by a sharp line of demarcation between the tanned and untanned skin, typically at the neckline or sleeves. This can be caused by prolonged sun exposure while wearing clothing that covers certain areas of the body, such as long sleeves or a hat. The covered areas remain pale, while the exposed areas become tanned.
There are a few reasons why you might want to even out a farmer’s tan. First, it can be unsightly. The sharp line of demarcation between the tanned and untanned skin can be unflattering and make it difficult to wear certain types of clothing. Second, a farmer’s tan can increase your risk of skin cancer. The UV radiation that causes a farmer’s tan can also damage the skin’s DNA, which can lead to the development of skin cancer.
