A New Weapon in the War on Wrinkles


L'Oréal unveils skin massager based on mechanobiology.

L'Oréal's Research & Innovation has rolled out its first-ever skin device based on mechanobiology discoveries. The launch comes after nine years of research in collaboration with the Mechanobiology Institute, Singapore (MBI) and the Institute of Medical Biology (IMB) in Singapore, the Institut Langevin and the Denis Diderot University in Paris.

The device has a unique massage head with anti-aging effects on wrinkles and the contours of the face, lips and neck. The launch marks the first time that L’Oréal R&I teams are able to apply this scientific field to skin, creating a massaging device able to improve the signs of aging.

L’Oréal R&I worked with Singapore’s Mechanobiology Institute to better understand the effects of mechanical stimuli on skin cells and to examine its potential applications in beauty devices. After years of research work, L’Oréal R&I discovered that vibrations could modify two key skin tissue properties: strengthen the dermal-epidermal junction and increase the extracellular matrix production. Best results were observed at a frequency of 75 Hz, which was identified as the optimal frequency generating 9000 micro-massages per minute. In collaboration with the Institut Langevin, L’Oréal researchers used advanced imaging techniques to study the movement of vibrational waves in ex vivo and in vivo skin and optimize their effect.

Finally, L’Oréal R&I teams in the US designed a three-point massage head able to maximize the stimulation. A clinical trial confirmed that several clinical signs of skin aging are modified, in particular the elasticity and firmness of skin around the edges of the face. All the results were published in PlosOne in 2017:
