That’s what’s happening with “skin barrier,” a phrase that’s taken over the skin-care conversation recently. As beauty editors, we tend to approach buzzy terminology with a healthy dose of skepticism, especially when it feels marketing-driven. But after hearing dermatologists consistently stress its importance, it’s clear this is one topic worth paying attention to. “The skin barrier—also known as the stratum corneum—is like ‘the roof of the skin,’” explains Idaho dermatologist Carl Thornfeldt, MD, founder and CEO of Epionce. And he would know: Dr. Thornfeldt has long studied barrier repair, beginning his research in 1989, and later developed patented technology to help repair the skin barrier, which is still used in Epionce’s formulas today.
