Microbiome on a bottle is often unregulated vibe. Look for what the formula actually does to the barrier.
Darker cells mean a higher score for this topic on that metric.

Quick facts
Oily, moist and dry sites host different communitiesSite mosaic
About 4.5–5.5 on much of adult skinTypical pH

Healthy skin is occupied; occupancy can be protectiveNot sterile
Ordinary washing removes dirt; it does not make a desertSoap vs sterilise
The skin microbiome is a site-specific film of bacteria, yeasts and other residents. Oily T-zones, moist folds and dry forearms are different neighbourhoods.
Healthy skin is not sterile. Acid, occupancy and lipids make it harder for some invaders to bloom.
This atlas is ecology, not a cosmetics prescription or a culture protocol.

English beauty aisles now say microbiome-friendly. Dermatology English is older: barrier, acne bacteria as a cast member, not a villain with a single soap.
Acne English
Cutibacterium (once Propionibacterium) is part of the cast. Kill-all marketing oversells.
Public-health desks
Hygiene pages talk about hands. Face microbiome talk is a different, slower conversation.

Frequently asked questions
Where should I start with Skin microbiome?
Read Identity → How they live → Body & health, then use compare rails.
Is this page advice for Skin microbiome?
Public-health education — not a care plan, prescription, or outbreak briefing.
What does the local lens add?
It names everyday desks for Beneficial allies before English norms look universal.
Are the scores a ranking of Skin microbiome?
No — editorial 0–100 browsing aids inside this atlas only.
How do I compare Skin microbiome to neighbours?
Use related cards and best-of / quiz rails after the first three chapters.
Which chapter is densest?
How they live and Body & health carry mechanisms; skim Identity first.
Can I cite these scores externally?
Treat them as atlas orientation, not certificates or forecasts.
What should I check before acting?
Primary desks for Beneficial allies: public-health desks and lab teaching frames.
