La Roche-Posay My Skin Track pH

My Skin Track pH is the wearable sensor for measurement of the pH level (pH value) of skin.

2018: Announcement

The cosmetic company L'Oréal provided on January 6, 2019 My Skin Track pH — the wearable sensor which allows to measure a pH value of skin independently. The sensor is developed by a dermatological brand of La Roche-Posay and the innovation laboratory L'Oréal Technology Incubator.

The device is described in video posted on YouTube channel of L'Oréal company.

As you know, the pH value (pH) of skin of the healthy person equals about 5.5 — an indicator lower, to 4.5, it is considered regulation, and higher or low value can speak about different skin violations, for example, of the increased dryness or fat content of skin. The unhealthy acid-base balance can also indicate predisposition to different skin diseases, for example, to eczema and atypical dermatitis.

Usually it is possible to define changes in skin pH or independently, having traced violations (for example, irritation and redness), or by means of a special tester which measures pH in the selected sweat, but only in the dermatologist's office. The special sensor, wearable on skin, from L'Oréal will allow to determine the pH level independently. Dermatologists for diagnosis of diseases will be able to use data retrieveds.

On the data which are available for January, the device measures a pH value from the user's sweat. The gadget will be required to be carried on a hand within 15 minutes until it changes color. After that it needs to be scanned in the application which analyzes the pH level and makes the personalized recommendations about care of skin using products of La Roche-Posay. Whether the sensor is subject to reuse, it is not specified.

The pH level — one of the main indicators of health of skin. It is in what my many patients are interested, but still it was very difficult to be measured out of clinical conditions. The sensor will help patients to impart healthy habits on care of skin, and dermatologists will be able to make accurate recommendations in treatment — the dermatologist of La Roche-Posay doctor Thomas Lager shared opinion.[1]

L’Oréal expects to put the sensor and mobile application to it on the market, but meanwhile is going to provide the gadget to the narrow group of people in partnership with the American dermatologists.^[2]
