Designed for all skin types, particularly those experiencing visible imbalance including sensitivity, redness and/or breakouts. Core Complex is a user-activated probiotic serum built around a strain-specific system.
Each application delivers a viable strain suspended in a multi-molecular hyaluronic acid serum designed for surface interaction, barrier support, and daily compatibility with the skin.
Activation occurs at first use via a dual-chamber system, releasing the probiotic into the serum.
At activation, the system delivers 8 billion CFU of live L. paracasei, protected by ProSym833™.
Single Core Complex restock coming soon.
Activation Protocol
ProSym833™
ProSym833™ is the protective environment designed to promote symbiosis on the skin and support the probiotic system within a defined functional window.
Why It Is Different
Most probiotic skincare relies on inactive extracts or shelf-stable formats.
Core Complex is built around a different model — one that requires viability to function as intended.
The system remains stable until activation, then enters a defined functional window where the biology is active.
This is not an open-ended product.
It is designed to be used as part of a defined application cycle.
