Monitor Indoor Air to Improve Your Dry Skin Care

Variations in the relative humidity and temperature of indoor air are directly linked to the temperature and water vapor content of outdoor air. Consequently, as the weather changes, the indoor drying stresses on skin also change—even though you can’t sense them. Adapting your skin care to the changing drying stresses requires two basic actions:

  • Monitoring the drying stresses on skin and
  • Managing the skin’s responses to those stressors.

As depicted in the accompanying diagram, a proactive approach to dry-skin prevention and care requires the monitoring of indoor humidity as well as the Dry Skin Index (DSI), which is a function of both relative humidity and temperature.

Proactive skin care to prevent and manage the potential for dry skin depends on the routine monitoring of indoor air for humidity and the Dry Skin Index.

Each monitoring activity corresponds to a specific management action. In the case of humidity, it is the operation of a humidifier that releases water vapor to indoor air. For example, when relative humidity in a bedroom consistently drops below 40%, operating a room humidifier while you sleep will help reduce drying stresses and enhance skin hydration. Monitoring the DSI on a daily basis will inform your skin-care choices regarding the application of moisturizing lotions and creams to areas of your body that are prone to dryness or flaky skin.

The DSI Sense, which is now under development, is the only sensor device that will measure both indoor humidity and the Dry Skin Index to inform your skin care practices. Check out our product page for more information and then sign up to be notified about its status.
