Freshly Activated Barrier Biology
Why Probiotics
Your barrier is an ecosystem.
We formulate for it
The skin barrier depends on a living microbiome, a community of microorganisms that helps regulate moisture retention, immune signaling, and barrier resilience. When that ecosystem is disrupted, the barrier fails.
STRATA-B uses a genome-sequenced probiotic strain designed to support barrier function at its biological origin, working with the living ecosystem at the skin barrier rather than coating the surface.
Core Complex
The live probiotic serum built for the skin barrier.
Genome-sequenced and freshly activated, Core Complex brings live probiotic biology to a barrier-first skincare ritual.
Real Results
Visible improvement across clarity, texture, and visible redness.
Individual results may vary.
Genome-Sequenced Strain
Not a generic probiotic blend. A clinically validated novel strain, selected for its documented association with barrier lipid synthesis and reduced transepidermal water loss.
Live Activation
Activated by you at first use, never pulled from shelf-stable inventory.
Barrier-First Design
Every component in the formulation exists to support delivery of the live organism and the environment around it. No fragrance, no colorants, no marketing ingredients. The vehicle serves the biology.
Fresh Use Window
Designed for use within 8 days of activation. Press the cap to release the probiotic into the serum, and the clock starts.
