It doesn’t matter what the chemistry concerned or the product produced, security is paramount, Elisabeth Bouhadana, international scientific director, L’Oréal Paris Worldwide, instructed attendees. She additionally talked about that earlier than a product reaches retailer cabinets, greater than 100 specialists and a collection of 100 controls can have been concerned in its creation.
Anne Colonna, international superior analysis director, defined how the corporate employs learnings from biology, chemistry, biotechnology, optics, biophysics and arithmetic to create novel pores and skin and hair care merchandise. She defined that L’Oréal groups are devoted to a few main domains: skin and hair data; the event of measurement strategies to extend data; and the analysis of ingredient security and efficacy, with the purpose of creating new ones.

The corporate employs a five-step security validation program. It contains scientific evaluation of actives, predictive in vitro checks on its Episkin reconstructed pores and skin adopted by human repeat insult patch checks (HRIPT) and dermatological checks. From there, L’Oréal conducts scientific and client tests beneath actual situations of use. Lastly, the corporate conducts “cosmetovigilance;” i.e., it stays on the alert for stories of questions of safety. Cosmetovigilance contains hostile impact reporting, evaluation of stories and danger administration.
“Our hyaluronic acid know-how was examined with greater than 15,000 purposes, throughout three totally different scientific research utilizing a number of biophysical measurements,” defined Bouhadana. “Multi pores and skin tone scientific research had been essential to verify the security and efficiency on all pores and skin sorts. Evaluations included essentially the most superior Raman spectroscopy to look at the penetration of HA, alongside Dermotrace measures as a way to correlate the exceptionally long-lasting replumping impact with the penetration of the micro HA.”
L’Oréal researchers are usually not averse to revisiting outdated chemistry. Firm executives stated they’ve revisited and reinvented the L’Oréal uncooked materials and formulation portfolios by incorporating inexperienced science ideas akin to circularity.

Micro hyaluronic acid penetrates the pores and skin and is ready to activate particular receptors, referred to as CD44, which stimulates the manufacturing of hyaluronic acid.”
Chen famous that macro HA rehydrates and smooths the pores and skin’s floor. Micro HA penetrates and plumps pores and skin from the within. This mix of HA ensures that the system won’t be sticky. L’Oréal researchers had been so happy with the outcomes from the HA that they created 9 True Match tinted replumping serums formulated with 1% micro HA.
