L’Oréal at the beginning of the yearshowed my skin track pH. This is a wearable sensor that allows you to make independent measurements of the pH of the skin. A novelty was developed jointly by the innovation laboratory L’Oréal Technology Incubator and the dermatological brand La Roche-Posay.
Normal for human skin is consideredpH value from 4.5 to 5.5. Going beyond these limits may indicate the presence of skin disorders, for example, the appearance of excessive oily or dry skin. Inaccurate acid-base balance is also a tendency to skin diseases: atypical dermatitis, eczema, and so on.
Changes in pH can be determined visually whenredness or irritation appears. Dermatologists also use special testers to measure sweat secretion. The new sensor, worn on the skin, will allow you to quickly determine this indicator without the help of a specialist. These data will already be used by dermatologists in the diagnosis of diseases.
The device will need to be worn on the arm forquarter of an hour, after which it will change color and transmit the readings to the corporate application. The program will analyze the pH level and give advice on skin care products using La Roche-Posay. Whether it will be possible to reuse the sensor is still unknown.
For the time being, L’Oréal plans to launch a sensor and an appropriate mobile application for a limited number of people in partnership with US dermatologists, to make sure that the invention is reliable.
