Published: Nov 28, 2023
Uncover the underlying causes of photosensitivity and how it affects your skin's response to sunlight.

Understanding UV Radiation
Ultraviolet (UV) radiation from the sun is a major cause of photosensitivity. It includes UVA and UVB rays, which penetrate the skin and can cause damage. This damage can lead to DNA mutations and immune system suppression, making the skin more vulnerable to reactions.
Genetic and Environmental Factors
Photosensitivity can be influenced by both genetic predispositions and environmental exposures. Conditions like lupus or porphyria increase sensitivity to UV light. Additionally, factors such as certain medications, cosmetics, or even occupational hazards can exacerbate the condition.
Reactive Oxygen Species
Exposure to UV radiation generates reactive oxygen species, which are harmful molecules that can damage skin cells. This oxidative stress not only contributes to photosensitivity but also plays a role in skin aging and cancer.
Frequently Asked Questions

Yes, certain medications can heighten sensitivity.
They are molecules that damage skin cells when exposed to UV radiation.
