L’Oréal 3D Prints Human Skin in Partnership With University of Oregon

Researchers at the University of Oregon have partnered with scientists from the renowned French skincare company L’Oréal to pioneer the first successful development of an artificial skin model closely resembling natural human skin. This collaborative effort aims to address the need for more accurate testing methods for cosmetics and skincare products, as well as to explore potential medical applications.

The artificial skin, which closely mimics the complexity and structure of natural human skin, is the result of a novel 3D printing technique invented by Paul Dalton, a professor at the university’s Phil and Penny Knight Campus for Accelerating Scientific Impact. This innovative method allows for the creation of multilayered skin-like cell colonies in a period of just 18 days.

A Two-Layer Approach To Realistic Skin

In the past, replicating human skin has been exceptionally challenging due to its diverse array of cell types and complex extracellular matrix. This matrix is crucial in facilitating cell communication and overall function, presenting significant hurdles in achieving accurate mimicry. However, unlike prior methods, Dalton’s technique can achieve unprecedented realism and functionality.
