More than 60 percent of the human body is comprised of water. Aside from just quenching one’s thirst, water is essential for replenishing skin by transporting nutrients and oxygen to cells.
When skin becomes dehydrated, both its appearance and protective function begin to deteriorate. There are a number of factors that contribute to water-loss in the skin such as sweating, environmental stressors like UV radiation and pollution, changes in season, and of course, drinking insufficient amounts of water. Beyond these contributors, the skin’s inherent ability to retain water from within the body is diminished by the aging process.
This aging phenomenon, coupled with exposure to environmental stressors, weakens skin’s natural moisture barrier, leading to more rapid water loss. The result? Skin can become dry, flaky, and dull. You might also notice that skin is less supple and bouncy when it’s dehydrated, which can create wrinkles on the surface. It is for precisely these reasons that good hydration—with water-replenishing topical products—is essential for a healthy, radiant complexion.
