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 strain-specific probiotic approach designed to support barrier function at its biological origin — not by coating the surface, but by working with the living ecosystem at the skin barrier.

Core Complex
The live probiotic serum built for the skin barrier.
Freshly activated, strain-specific, and designed for use within a defined functional window — Core Complex brings live probiotic biology to a barrier-first skincare ritual.

Real Results
Visible improvement across clarity, texture, and visible redness.
A look at early outcomes observed across real-use application cycles. Individual results may vary.




Strain-Specific Biology
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. Not pulled from shelf-stable inventory. A user-activated system with a defined functional window.
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. Activation occurs when you suppress the plunger, releasing the probiotic system into the HA matrix. Potency is time-dependent from that moment.
