The month of October for most of the United States marks the transition between the warm, humid, part of the year and the cooler months. Cooler weather produces higher indoor drying stresses on skin due to lower indoor humidities and temperatures. Now is a good time to evaluate your skin-care practices before dry, itchy skin develops!
You observe some flaky dry skin on your face, arms or legs and so then you decide to buy a moisturizing lotion or cream. But unless you already know what product you are going to purchase, it’s somewhat daunting to select a moisturizer because of the multiple brands available as well as the wide variety of different formulations and ingredients.
As indoor relative humidity levels decline due to seasonal changes in outdoor water vapor levels, it is time to consider a room humidifier to increase humidity. The effectiveness of a room humidifier depends on how much water vapor it emits and the building properties of the residence.
Petrolatum is widely used in moisturizing lotions and creams because it helps prevent the diffusion of water from within skin to ambient air. It is actually a mixture of hydrocarbons in the form of a petroleum jelly that was first discovered in 1859 by a chemist in Pennsylvania.
