Nestlé Skin Health has launched a new app to combat skin scratching even when the user is not aware of it. This technology is geared towards patients who scratch their skin while sleeping and cognitively impaired patients with Alzheimer’s or Dementia. The app, called Itch Tracker, tracks the number of scratching incidents and the duration of each incident. Though the app can be used anytime, Nestlé is particularly interested in sleep incidents due to sleep disruption.
