How does your skin care respond to indoor dermal stresses?

The Key Challenges

You cannot sense the magnitude of indoor drying stresses on your skin due to changes in humidity and temperature. Consequently, it is not easy to deal with dry skin in a timely fashion.

Indoor drying stresses are linked to changes in the weather, and therefore skin-care practices should adapt accordingly to promote healthy skin.

Maintaining healthy skin gets more difficult as you age due to biochemical changes that impact the barrier function of the outermost skin layer (stratum corneum).

Failure to keep aging skin hydrated increases the risk of low-level dermal inflammation, which has been connected to various health conditions ranging from eczema to cognitive impairment.

The Solutions

Monitor the following skin-care diagnostics with the DSI Sense + app to guide your year-round skin care:

  1. the Dry Skin Index (DSI), which measures the external drying stresses on skin due to changes in indoor temperature and relative humidity, and
  2. the hydration level of the stratum corneum in contact with ambient air, calculated from indoor relative humidity.

Adapt your skin care based on the magnitude of indoor dermal stresses so that you can achieve healthier skin care with:

  1. the timely application of the appropriate moisturizing creams and lotions to keep skin hydrated, and 
  2. the operation of a room humidifier to increase indoor humidity along with skin hydration.

Skin Sim app

See how dermal drying stresses change at a reference house where you live.

This app conducts custom simulations for your location using local climate data and an indoor air model.

Based on the simulation results, purchase a DSI Sense device to help you monitor indoor dermal stresses to improve your skin care!
