I tried the essence as a rich toner to hydrate my dry skin and strengthen my skin barrier. It doesn't seem to work for my skin though. It provides surface hydration but nothing more than that. It also causes redness. I think the long ingredient list is too much for my skin as a first step. I'm not sure if it's the ferment-niacinamide combination or the entire mix of ingredients.

La texture est sympa, et il s’intègre très bien dans ma nouvelle routine pour peau déshydratée. Je recommande !
