AI Article Synopsis
- The study investigates how skin type affects sunburn sensitivity in individuals with vitiligo, who have white patches in otherwise pigmented skin.
- Researchers used UVB lamps to expose both affected (lesional) and unaffected (non-lesional) skin in 33 vitiligo patients, categorizing them by skin type (II-VI).
- Findings indicate a correlation between skin type and UV sensitivity, suggesting there may be protective mechanisms beyond melanin, potentially involving antioxidant status.
Article Abstract
It is assumed that skin is protected against sunburn by melanin. In patients with vitiligo, there are white patches in the normal pigmented skin. We noticed that there is a difference in burning capacity of these white patches between people with different skin types. With UVB 311 nm lamps, we irradiated both lesional and non-lesional skin with increasing doses in 33 patients with vitiligo, divided into 5 groups according to skin type (II-VI). Twenty-four hours later we assessed the minimal erythema dose and found a correlation between skin type and UV sensitivity in both lesional skin and normal skin. We suggest that there must be a protection mechanism, other than that offered by melanin pigmentation. The antioxidant status may play a role in this phenomenon.
