French cosmetics firm L'Oreal is teaming up with bio-engineering start-up Organovo to 3D-print human skin.
It said the printed skin would be used in product tests.
Organovo has already made headlines with claims that it can 3D-print a human liver but this is its first tie-up with the cosmetics industry.
Experts said the science might be legitimate but questioned why a beauty firm would want to print skin.
L'Oreal currently grows skin samples from tissues donated by plastic surgery patients. It produces more than 100,000, 0.5 sq cm skin samples per year and grows nine varieties across all ages and ethnicities.
Its statement explaining the advantage of printing skin, offered little detail: "Our partnership will not only bring about new advanced in vitro methods for evaluating product safety and performance, but the potential for where this new field of technology and research can take us is boundless."
