L’Oreal unveils a new prototype for skincare

by Arun Shirishkar

The new prototype by L’Oreal is a wearable microfluidic sensor to measure the skin’s pH levels.

L’Oreal has introduced a prototype of the latest innovation from the L’Oréal Technology Incubator at the 2019 Consumer Electronics Show. My Skin Track pH by La Roche-Posay is the first-of-its-kind wearable sensor. It has an accompanying app to measure personal skin pH levels and create customized product regimens.

My Skin Track pH has been honored with a CES 2019 Innovation Award. It has been named as “Best of Innovation” winner in the Wearable Technology Products category. The sensor was co-developed with L’Oreal’s skincare brand La Roche-Posay, which works closely with dermatologists to develop safe and effective skincare products.

The pH scale ranges from acidic to basic, on a spectrum measured from 0 to 14. Healthy skin pH exists within the slightly acidic range between 4.5 and 5.5. When pH balance is compromised, it can trigger inflammatory responses. Such responses can cause or exacerbate common skin concerns including dryness, eczema, and atopic dermatitis.? A small, thin, flexible sensor, My Skin Track pH represents the next frontier in personalised skincare technology for L’Oreal. It captures trace amounts of sweat from skin pores through a network of micro-channels, providing an accurate pH reading within 15 minutes.

My Skin Track pH provides an accurate pH reading via a simple two-step process:

  • The wearer places the sensor on their inner arm, leaving it in place for 5-15 minutes—until the center two dots take on colour.
  • Next, the wearer opens the My Skin Track pH app and photographs the sensor. Utilising an advanced algorithm, the app reads the pH measurement, as well as the wearer’s local sweat loss—the rate of perspiration on the skin’s surface—to assess skin health and make customized La Roche-Posay product recommendations to care for skin and balance pH.

“This new prototype represents the next step in La Roche-Posay’s beauty tech journey. We are committed to bringing scientific progress directly to consumers, to help them take great care of their skin,” said Laetitia Toupet, Global General Manager of La Roche-Posay.

My Skin Track pH will initially be introduced in 2019 through select La Roche-Posay dermatologists in the U.S., with the goal of amassing new research and ultimately launching a direct-to-consumer product
