GlossarySun Exposure (Sunlight)

exposure to the sun's ultraviolet rays affecting skin health

Sun exposure, also known as sunlight exposure or UV exposure, refers to the amount of time the skin is exposed to the sun's ultraviolet (UV) rays. While moderate sun exposure is essential for the production of vitamin D, excessive exposure can lead to skin damage, premature aging, and an increased risk of skin cancer.
