My Skin Track pH by L’oreal

28

L’Oréal demonstrated My Skin Track pH at the beginning of the year. This is a wearable sensor that allows you to make independent measurements of the skin pH. The novelty was developed jointly by the L’Oréal Technology Incubator innovation laboratory and La Roche-Posay dermatological brand.

The pH value from 4.5 to 5.5 is considered normal for human skin. Going beyond these limits may indicate the presence of skin disorders, for example, the appearance of excessively oily or dry skin. Inaccurate acid-base balance also occurs when a person is prone to skin diseases: atypical dermatitis, eczema, and so on.

Changes in pH can be determined visually when redness or irritation occurs. Dermatologists also use special testers to measure sweat secretion. The new sensor, worn on the skin, will allow to quickly determine this indicator without the help of a specialist. These data will be used by dermatologists while diagnosing diseases.

The device has to be worn on the arm for a quarter of an hour, and then it will change color and transfer the results to the corporate application. The program will analyze the pH level and give advice on skin care products using La Roche-Posay products. It is still unknown whether it will be possible to reuse the sensor.

For the time being, L’Oréal is planning to launch its sensor and an appropriate mobile application for a limited number of people in partnership with US dermatologists to ensure the reliability of the invention.
