Redefining moisturiser – Soft Matter article in Chemistry World

Scientists in Sweden have probed the outermost layer of skin to gain molecular insights into how naturally occurring molecules in this layer protect it from drying out.

Healthy skin with a normal degree of hydration is soft and pliable. This is not the case for dry skin, which is brittle and easily cracks. To treat dry skin it is common to apply a cosmetic containing a humectant  ̶  a type of “moisturiser” – like glycerol or urea. These substances are also components of natural moisturising factor (NMF), a group of molecules naturally present in the skin barrier. The beneficial function of these compounds if often claimed to be their capacity for increasing skin hydration, although the underlying mechanisms are generally described with a rather weak molecular basis.
