It is fermented by the compound bifidobacteria (known as bifidus yeast in the industry). It is a probiotic product that thoroughly improves the skin condition and can be classified as a skin micro-ecological active matter. The core ingredient of the Estee Lauder Advanced Night Repair is the bifidus yeast. The anti-ageing active ingredients extracted from the lysate of bifidobacteria through biotechnology can effectively protect skin, reduce the damage caused by ultraviolet rays to the skin, activate the immuno-suppressive process, stimulate endogenous skin protection, and promote cell repair. It can reduce skin spots, brighten the skin, reduce the number and degree of wrinkles, and smooth the skin. Bifidus yeast can promote cell repair and support the endogenous protection mechanism to fight against skin aging.

PuriBifido is created through the fermentation of composite bifidobacterium (commonly known as Bifida) groups. It is a bifidobacterium derivative that can completely improve skin states with the
