Final answer:
Solar cheilitis is more common in fair-skinned adults due to their lower levels of protective melanin. Protection from UV light is crucial to lower the risk of developing skin conditions like solar cheilitis.
Step-by-step explanation:
D. Fair-skinned adults Solar cheilitis is more commonly seen in fair-skinned adults. This is because individuals with lighter skin have less melanin, which is the pigment that provides some protection against the harmful ultraviolet (UV) rays of the sun. As melanin acts as a natural sunscreen, those with darker skin have a lower risk for solar cheilitis due to their increased melanin levels. Besides exposure to UV light, other risk factors for skin cancer include having a family history of the condition, many moles, or a weakened immune system. It's important to protect the skin from excessive UV exposure by using sunscreen and protective clothing to lower the risk of developing skin cancer, including solar cheilitis.

Solar cheilitis, also known as actinic cheilitis, is a condition characterized by inflammation and damage to the lips due to long-term sun exposure. Fair-skinned individuals are more susceptible to this condition because they have less melanin, which helps protect the skin from harmful UV radiation.
