No, we’re not talking about short days, shoveling the walk, or the morning commute. We’re talking about the atmospheric humidity which, together with sauna-like indoor heating, can bring humidity levels as low as 5-10%. And what happens to skin not accustomed to such conditions? It struggles to keep up by building its barrier, but that adaptation can take a while, and often gums up the whole system.
There is a cascading impact that ripples through the skin’s infrastructure when there’s not enough moisture. The lipid layers stall, the normally plump skin cells flatten and create fissures. The shedding process, which is dependent on water, stops functioning, so that dead cells stay stuck in the skin’s surface, and then break off in scaly chunks. Cracks in the skin make it more vulnerable to germs and permeation of all kinds of things. The skin can usually adapt over time, but in the meantime, it’s not a pretty (or healthy) picture.
