It has everything to do with cortisol. As you may know, when your cortisol levels are ramped up, your collagen, hyaluronic acid, and lipids tend to suffer; those other processes are put on the back burner in order for your body to focus all its energy on that “fight-or-flight” response. As these three components deplete over time, it can lead to “dermal thinning,” where the skin can actually become thinner and less elastic. As a result, your skin barrier weakens, which can kick-start a smattering of concerns—think irritation, dryness, and premature aging.
