Get the DSI Sense

The DSI Sense monitors the indoor drying stresses on your skin!

The Problem

You cannot sense the magnitude of indoor drying stresses on your skin due to changes in humidity and temperature. This can impact your skin care because we spend most of out time indoors!

Your Skin

Indoor drying stresses are linked to changes in the weather, and therefore skin-care practices should adapt accordingly to promote healthy skin. This is even more important for mature skin due to biochemical changes that impact hydration.

The Solution

Monitor the Dry Skin Index (DSI), which measures the external drying stresses on skin due to changes in indoor temperature and relative humidity.

How to use: preventing seasonal dry skin

The DSI Sense is easy to use—simply download the app from the either the iOS or Android store, set up an account in the app, plug the device into its USB power adapter, and use the app to set up the WiFi connection.

Once logged in, you’ll see the dashboard screen with gauges for the Dry Skin Index and the estimated level of hydration for the outer layer of the stratum corneum.

For a quick update, the LED on the DSI Sense also shows the current level of the Dry Skin Index as one of 5 color-coded categories.

Because each person’s skin responds differently to external drying stresses, periodically check the dryness of your skin and compare it to the Dry Skin Index and hydration level. Adjust the use of moisturizers according to the appearance of your skin and the levels of the two diagnostics shown in the app and LED indicator.

Optimize your skin-care routines!

With a DSI Sense you'll always be ready to respond to indoor drying stresses related to changes in the weather.

The app summarizes the stress level due to changes in indoor temperature and humidity. It also provides suggestions regarding the use of moisturizers to care for your skin.

Based on the DSI level, you can change your selection of moisturizing lotions and creams, as well as the frequency of applications to areas of skin prone to dryness.

Know when to set up your room humidifier(s)

When the DSI Sense shows values of the Dry Skin Index above 6, it is time to consider the use of a room humidifier to supplement your normal skin-care routine.  For example, running a humidifier in your bedroom at night would be one convenient way of hydrating your skin while you sleep. Or, if you have a home office, run a room humidifier when you are working.

Still Not Sure if the DSI Sense is for you?

Not to worry! We have prepared the FREE  Skin Sim app for Android and iOS devices that simulates the indoor drying stresses on skin at a reference house in a US community that you select.

The app uses meteorologic data from NASA and the National Weather Service as input to a simulation model. Outputs include:

  • Current level (and range) for the Dry Skin Index (DSI)
  • Monthly DSI values
  • Year-long simulation of daily DSI values
  • Number of days above DSI levels of 4,5, and 6
  • Statistical summary

Based on these custom results, and knowledge of how your skin responds to indoor drying stresses, you can safely decide whether the DSI Sense would help inform your skin care.


Testimonial from Dave Layton, creator of the DSI Sense:

“I remember having dry, flaky skin at different times of the year as I got older, but never really knew why I was experiencing the skin dryness. As a result, my skin-care practices were erratic, and unproductive.

However, since I’ve been using the DSI Sense, I’m much more aware of the drying stresses on my skin and now I adjust my use of moisturizers accordingly. I am happy to see that my skin is much healthier looking!
