Slapping on microbiome serum morning AND night sounds smart. It’s not — you’re basically wasting half the bottle.
The living bacteria in this stuff need specific conditions to survive. Sunlight kills them. Your morning SPF creates a chemical barrier that suffocates the good bugs before they even settle in.
Ourself Microbiome Serum — $68 for 30ml. The claim that made me roll my eyes: “rebalances your skin’s ecosystem.” I’ve heard that from 47 brands and none delivered.
Postbiotic Ferment
Feeds your existing bacteria instead of dumping foreign ones on your face
Ceramide Complex
Repairs the barrier so the good bugs actually stick around
Zinc PCA
Controls oil without stripping — surprisingly gentle for an active

Three hero ingredients that don’t get enough credit. The prebiotic inulin feeds your skin’s natural bacteria — most brands skip this step. Lactobacillus ferment creates a protective biofilm that lasts 6-8 hours post-application.
- Inulin: Feeds good bacteria like fertilizer for grass
- Lactobacillus Ferment: Creates a living shield on your skin
- Ceramide NP: Plugs gaps in barrier so bacteria don’t escape
- Zinc PCA: Keeps fungus in check without nuking everything

Sinks in 8 seconds — feels like water but leaves a weirdly dry finish. I hated it the first week. It’s not moisturizing. You need a separate hydrator underneath.
Week 3 my chin stopped getting those tiny white bumps. Unexpected win: my sunscreen stopped pilling. The serum creates a grip layer that makeup actually sticks to.
Fewer breakouts by week 4. Less redness around my nose. Still had texture on my forehead — it’s not magic. My skin stopped freaking out when I skipped a night.
Use it only at night. Morning application is a marketing gimmick — the bacteria die under SPF and your money evaporates. Nighttime gives them 8 hours to actually work.
