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.

J Invest Dermatol 2025 Oct. 29:S0022-202X(25)03509-2 A new study from the University of Otago in Christchurch, New Zealand, has found that dietary vitamin C intake directly enhances collagen production and skin renewal, offering clinical confirmation that nutrition may play a central role in skin physiology. Published in the Journal of Investigative Dermatology , the investigation established a strong, dose-responsive relationship

A registry study from Lund University in Sweden shows a possible increased risk of basal cell carcinoma with certain blood pressure medications. Because the risk increase is relatively low, 9% or lower, the researchers do not recommend treatment discontinuation. Instead, physicians should inform their patients that extra sun protection may be needed. The study’s lead author, Johan Kappelin, PhD, is a senior consultant at the dermatology clinic in Landskrona, Sweden. “Basal c

Patients with severe AD have higher rates of venous thromboembolism than those with moderate AD or without AD.
