Gut and Atopic Eczema:

A health gut is very important for the health of your skin; and is directly related with Atopic Dermatitis (Eczema).
Low Amount of Bifidobacteria in Adult

There is a report that children with eczema have a more diverse set of bacteria in their guts as compared to non-affected children. Their gut bacteria proportions also look more like an adult’s microbiome over a healthy toddler's (1). When comparing microbiomes between 6 and 18 months babies, it was found that the amount of bifidobacteria declined dramatically from 23% (at 6 months) to 13% (at 18 month). In addition to bifidobacteria, the relative amount of Lactobacillus also decreased from 4% to 0.3%.
Low Amount of Bifidobacteria in Atopic Eczema

The amazing thing is that bifidobacteria were 3 times more abundant in healthy children compared to the children with eczema. This shows the importance of bifidobacteria in skin health for children who have eczema.
Bifidobacteria
Therefore, bifidobacteria could do the important role for maintaining the healthy skin.
