Sun Sensitivity

Sun sensitivity is an increased susceptibility to UV radiation, leading to exaggerated sunburn reactions and potential long-term skin damage. It can be triggered by medications, medical conditions, or topical products.

Sun sensitivity, also known as photosensitivity or phototoxicity, refers to an increased susceptibility of the skin to the harmful effects of ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. This heightened sensitivity can lead to exaggerated sunburn reactions, including redness, blistering, itching, and skin pain, even after minimal sun exposure. In severe cases, it can cause systemic symptoms like fever, chills, and nausea. Some medications, medical conditions, and topical products can increase the risk of sun sensitivity. Photosensitivity can manifest as phototoxic reactions (caused by direct damage to the skin from light and a substance) or photoallergic reactions (an immune response triggered by light and a substance). Chronic photosensitivity can lead to premature skin aging, increased risk of skin cancer, and persistent skin discoloration. The specific manifestations and severity depend on the individual, the triggering substance, and the intensity and duration of UV exposure.
