A Regenerative Signaling Complex
Cellular Integrity Factor is Bionassay’s proprietary regenerative complex designed to support the skin’s innate intelligence.
At its core is a precise composition of Milk Secretome, Allantoin, and Escin, bioactive molecules selected for their ability to help maintain cellular structure and optimize biological communication within the skin.
Healthy skin depends on more than surface renewal. It relies on coherent cellular signaling, the continuous exchange of biochemical messages that instruct repair, regulate inflammation, and preserve barrier function. When this communication becomes disrupted by environmental stress, inflammation, or aesthetic procedures, the skin’s structural integrity declines.
Cellular Integrity Factor works to help preserve both:
- Cellular integrity — supporting the strength and stability of skin cells
- Signaling integrity — encouraging efficient communication between cells
Milk Secretome delivers bioactive mediators that help reinforce regenerative signaling pathways.
Allantoin supports visible recovery and barrier reinforcement.
Escin helps maintain microvascular stability and structural resilience.
The result is skin that appears calmer, stronger, and more responsive over time.
The full composition remains proprietary, formulated to activate the skin’s own capacity for balance and regeneration.
Our ingredients are sourced without engaging in mass or wild harvesting. Additionally, 100% of our ingredients are traceable back to the source, to ensure fair working condition and the efficacy and stability of our formulas.
