Winter Skin

Your skin changes in winter, rarely for the good. 

The outer barrier layer of the skin, known as the stratum corneum, does not do as good a job of keeping water in and keeping chemicals out. 

This development comes as no surprise as the weather grows colder and the air becomes drier.

Research has shown the negative effects of low relative humidity and temperature on skin barrier function. 

The result is that skin not only dries out, but is also more susceptible to the itching and pain that comes with irritation. If someone has a history of eczema, worsening of that disease may also be more likely to occur. 

One study has also shown that application of moisturizer will improve these changes to skin on the face that are caused by winter. 

Moisturizers work their magic by providing the environment necessary for the skin barrier to repair itself.

Effective moisturizers will have two key components—a humectant component, such as glycerin, to attract and retain moisture; and an occlusive component, such as dimethicone, to seal in moisture and prevent further water loss.

Next time, we will talk more about these two proven ingredients, how they shape formulation development, and ultimately the ingredient listings in the commercial products you see on every shelf.

Make an effective two-component moisturizer the cornerstone of your winter regimen for your skin to be its best!
