These findings were published online ahead of print in the Journal of the American Academy of Dermatology . In the paper, the authors note that emerging reports suggest potential dermatologic adverse effects associated with GLP-1RA use, particular

Natural compounds that can be used in sunscreens may also be beneficial for skin health and blood pressure.

The University of Oulu, Finland study, published in the Journal of the American Geriatrics Society ,  examined the effects of AD on the quality of life of older people in northern Finland. The research was ba

Researchers have discovered a new approach to protect patients from radiation-induced skin damage during cancer treatments.

In a study published in Scientific Reports , Agata Bienkowska and colleagues found that consistent sunscreen application can prevent many of the fundamental biological disruptions caused by repeated UV exposure. The findings build on decades of evidence linkin

DKK3 in keratinocytes orchestrates radiation-induced skin hyperplasia, dermatitis, and fibrosis. Radiation-induced reactive oxygen species (ROS) increase DKK3 expression in keratinocytes, which subsequently activates canonical Wnt signaling through autocrine TGF-β signaling. Elevated DKK3 levels in keratinocytes drive hyperproliferation and hyperplasia, promoting the polarization of macrophages toward a profibrotic phenotype. These polarized macrophages, in turn, upregulate..

Researchers recently reviewed the relative efficacy of 22 immunomodulatory treatments for scalp psoriasis.

The findings, published Jan. 22, 2026, in Cell , outline a neural crest–derived fibroblast program and a ROBO2–EP300 signalling pathway that together drive a more regenerative, less-fibrotic pattern of repair.​
