Skin Mitochondrial Protection by R0090948A Active

28. september 2026 opdateret af: L'Oreal

A Monocenter, Double-blind, Comparative, Controlled, Randomized Study to Evaluate the Effect of Active R0090948A at 1%, Compared to Vehicle, on Mitochondria With or Without UV Stress in Healthy Participants.

The study intends to evaluate the skin longevity through mitochondria protection efficacy of cosmetic products after 3 months of product application, under UV exposures or not, followed by skin biopsies.

Primary objective:

- To assess the efficacy of the investigational active in skin mitochondria protection, after twelve weeks of product application with or without UV stress, by morphological and texture parameters measurements

Secondary objectives:

  • To assess efficacy on other biomarkers of skin mitochondria with biopsies histological analyses
  • To assess efficacy by skin colorimetric measurements
  • To assess efficacy by visual scoring of skin pigmentation and erythema
  • To assess efficacy by skin untargeted full proteomic analysis
  • To assess efficacy by skin metabolomic analysis

Safety: to follow the Adverse Events all along the study
