Vacation Tan Damages Beneficial Skin Bacteria

Researchers have found that four weeks after vacation, the participants in the experiment had significantly reduced diversity of skin microorganisms, even among those who did not acquire a strong tan. Over time, the number of bacteria recovered. Scientists believe that such fluctuations are a worrisome sign, as a sharp change in microbiota diversity can lead to conditions such as dermatitis, eczema, and psoriasis.
