During investigation, the company found a supplier that developed a complex incorporating bifidus ferment lysate in milk proteins. “The [engineered] bifidus ferment lysate is immersed in milk proteins to strengthen the skin,” said Marc.

Although the actives are no longer alive, they are still active. The company formulates the complex at 5%.

Also formulated into the product is soybean seed extract and hydrolyzed rice protein. These ingredients were added for their claimed ability to help protect the skin barrier and build collagen.

In vivo and In vitro Testing
As most cosmetic manufacturers know, science sells. Thus during its ingredient search, the company placed heavy emphasis on efficacy testing and found that, with the particular ingredient chosen, four different tests were performed, two of which relating to the ingredient’s interaction with ultraviolet (UV) light.

“The tests showed that the bifidus complex strengthened the skin against UV light, meaning that the chemical changes that occur when the skin interacts with the sun were reduced,” added Marc.
