Tanning bed use is tied to almost a threefold increase in melanoma risk, and findings from new research show these devices cause melanoma-linked DNA damage across nearly the entire skin surface. The findings were reported in a study published in Science Advances  led by Northwestern Medicine in Chicago and the University of California, San Francisco. This new study “irrefutably” challenges claims from the tanning industry that tanning beds are no more harmful than sunlight by

Patients with chronic skin diseases have higher rates of addictive behaviours.

A new analysis in JAMA Dermatology  reports that nicotinamide, a form of vitamin B3, was associated with a meaningful reduction in incident skin cancers among U.S. veterans with a prior history of the disease. The findings point to an inexpensive, orally administered chemopreventive option that could help clinicians manage an especially high‑risk population. The study drew on data from more than 12,000 veterans followed over 25 years who had previously received nicotinamide a

Tyrosinase (Tyr) catalyzes hydroquinone (HQ) oxidation via two main pathways. The HBQ pathway directly oxidizes HQ to 2-hydroxy-1,4-benzoquinone (HBQ), which dimerizes and forms hydroquinone-eumelanin (HQ-EM). The BQ pathway involves dopaquinone (DQ)-mediated redox exchange producing p-benzoquinone (BQ), which reacts with cysteine (Cys) to form 2-S-cysteinylhydroquinone (Cys-HQ) and further oxidizes to hydroquinone-pheomelanin (HQ-PM). These pathways illustrate the enzymatic

46.3% of female patients with psoriasis have been exposed to at least one type of intimate partner violence.

The research, published December 12 in Science Advances , reports that tanning bed users in their 30s and 40s harbour more mutations in their skin cells than nonusers who were in their 70s or 80s.

The study, published in Cell Death & Differentiation , shows that the fatty acid-binding protein FABP5 drives ferroptosis, a particular form of cell death, and amplifies inflammatory processes in the skin. Blocking this protein significantly improved the skin change

Probiotics as adjunctive therapy for acen vulgaris do not result in a statistically significant improvement in disease severity.
