L’Oréal researchers have been working for over twenty years to gain a better understanding of the role of adult stem cells in skin and hair regeneration.
This knowledge has already been used as the basis of products aimed at preserving the integrity of skin and hair and repairing aging skin.
Aging skins undergoes a number of changes that L’Oréal scientists are trying to better understand and address.
One of the tools L’Oréal has helped to develop is in vitro reconstructed human ski, which can be used to address questions of basic science as well as allowing the evaluation of the efficiency and safety of products.
L’Oréal stem cell research has yielded active ingredients that are effective in protecting against and repairing the effects of aging.
When it comes to hair, understanding the biology of hair stem cells is essential for comprehending the causes of hair loss and for proposing new approaches to preventing and treating this phenomenon.
The L’Oréal team found that melanocytes are susceptible to stress because they do not possess a key enzyme called TRP2. Active ingredients that mimic this enzyme could serve as the basis for treatments to prevent hair whitening in the future.
Dr Bruno Bernard, of the Hair Biology Group, L’Oréal: “In the future, and because of the key role of stem cells, we might end up with new strategies to prevent skin aging, hair loss and hair whitening. At L’Oréal, we first want to understand the biology and, from our discoveries, we want to design new strategies. But clearly we have to do that very carefully, bit by bit, respecting all the ethical problems. This is the way we work.”
