Not too little — one microbe overflowing.
Against "grow your skin bacterial diversity," chronic skin disease is usually the overgrowth of one microbe and skin alkalinization.
~10%
Staphylococcus aureus detection rate
~70%
The same microbe, detected this much
Overgrowth
The rising pattern of Malassezia and staph
It may be a problem of reducing the one overflowing microbe — not of adding more bacteria to fix it.
Once it tilts, it rolls on its own.
Malassezia overgrows
The skin surface tilts toward alkaline.
An environment for staph
The alkaline surface makes it easy for Staphylococcus aureus to grow.
Water loss + further alkalinization
Staph overgrowth breaks down the barrier and adds more alkalinization.
Skin immunity collapses → chronic dermatitis
Once the vicious cycle sets, it becomes chronic.
A hypothesis that raw vegetables and alkaline foods create a similar environment in the mouth — skin, mouth, and gut do not act separately.
Not restoring diversity — targeting the overgrown microbe.
The approach is not "add more good bacteria" but reduce the overflowing microbe and restore the skin barrier and pH. Resistant organisms (MRSA) in particular are hard to control with a single method and may need thorough, combined management — any specific prescription must be decided under a physician's guidance.
