Tanning in body dysmorphic disorder (BDD) has not previously been studied. In this study, 200 subjects with BDD were evaluated with measures to examine the prevalence of BDD-related tanning--i.e., darkening one's skin color by direct exposure to sunlight or artificial light which is motivated by a desire to improve a perceived appearance defect (i.e., a BDD concern). We also examined clinical characteristics of individuals who engaged in BDD-related tanning. 25% (95% CI, 19.0%-31.0%) of subjects reported BDD-related tanning. Among tanners, the skin was the most common body area of concern (84.0%). All tanners experienced functional impairment due to BDD, 26% had attempted suicide, and quality of life was markedly poor. 52% of tanners had received dermatologic treatment, which was usually ineffective for BDD symptoms. Tanners were more likely than non-tanners to compulsively pick their skin. In conclusion, tanning--a behavior with well-known health risks--is a relatively frequent BDD-related behavior.

The utilization of chromium free tanning agents generates lots of pollutants such as chromium containing wastewater and sludge. Besides, trivalent chromium may be converted into carcinogenic hexavalent chromium under certain conditions, causing permanent harm to the human body. Therefore, the promotion of chromium free tanning technology is extremely significant.

Background And Objectives: Basal cell carcinoma (BCC) is the most common form of skin cancer, originating from basal cells in the skin's outer layer. It frequently arises from prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds. Although BCC rarely metastasizes, it can cause significant local tissue damage if left untreated.

Seasonal polyphenism enables organisms to adapt to environmental challenges by increasing phenotypic diversity. exhibits remarkable seasonal polyphenism, specifically in the form of summer-form and winter-form, which have distinct morphological phenotypes. Previous research has shown that low temperature and the temperature receptor regulate the transition from summer-form to winter-form in by impacting cuticle content and thickness.

Background: Cutaneous melanoma incidence varies consistently across body sites between men and women, but the underlying causes of these differences remain unclear. To date, no prospective studies have examined risk factors for melanoma separately for men and women according to body site.
Objectives: We aimed to examine the association between identified constitutional, genetic and environmental risk factors for invasive melanoma of different body sites among men and women.

Background: Tanning bed users have a significantly increased risk of melanoma, but it remains unclear how indoor tanning drives melanomagenesis. Tanning bed radiation is often thought of as a substitute for natural UV radiation despite differences in the maximum doses, UV content, body sites exposed, and patterns of melanoma that arise.
Methods: To better understand the epidemiologic trends and etiology of melanoma associated with tanning bed use, we described the patterns of melanoma in patients with quantifiable tanning bed usage and performed exome sequencing of 182 melanocytes from normal skin of a subset of these patients.
