Lactobacillus Ferment Lysate in Collagen Firming Night Pak: Conditioning Care

Separately, researchers studied a Lacticaseibacillus rhamnosus IDCC 3201 lysate in a cream. They worked with two separate groups of women, and neither group compared the cream with the same cream made without the lysate, so both results belong to the study cream as a whole rather than to the lysate on its own. In a randomized, investigator-blinded comparison in 24 women, forearm skin went through a skin-drying challenge before the cream went on one site while a paired site stayed untreated; over five days, measured water-loss recovery improved against untreated skin. In the other group, 21 women used the cream on the face for four weeks, and hydration rose against baseline.
