Which of the following skin types is most sensitive to UV radiation?

Type I skin is characterized by very fair skin that often burns and does not tan. Individuals with this skin type have low levels of melanin, which means they have minimal natural protection against UV radiation. This lack of melanin makes them highly susceptible to the damaging effects of UV rays, including sunburn, skin damage, and an increased risk of skin cancer.

Furthermore, people with Type I skin typically have characteristics such as red or blond hair and light-colored eyes, which also contribute to their sensitivity to UV exposure. The other skin types, while also affected by UV radiation, have a higher capacity for melanin production, which allows them to tan and provides some natural protection against UV damage. Therefore, Type I is the most sensitive skin type to UV radiation due to its minimal pigmentation and higher likelihood of burning.
