This is a review article, not an experiment with measurable results. It summarizes what we already know about trehalose—a natural sugar found in bacteria, plants, and insects—and its potential uses in cosmetics, food, and medicine. The authors highlight that trehalose can stabilize proteins and other molecules, but the abstract doesn't provide specific skin benefits or efficacy data.
The authors reviewed existing published research on trehalose's chemistry, how it works in living organisms, and its current and potential industrial applications. This is a literature review, not original research testing trehalose on human skin.
