NICD does not replace toxicological safety evaluation under EU Regulation 1223/2009 or equivalent legislation. It provides an additional assessment layer addressing neurological compatibility, sensory predictability, and cognitive accessibility.
Products applying for NICD verification must already be fully compliant with applicable cosmetics regulations before assessment begins.
NICD governs formulation, packaging, delivery systems, and all user communication — assessed as one integrated system.
"NICD recognises neurological diversity as a fundamental dimension of human variation."
Communication, sensory cues, and performance must align without deception or omission. Honesty is a design safety parameter.
A routine performed consistently delivers greater wellbeing than a perfect routine performed once and abandoned.
Sensory and behavioural predictability is as critical as microbial and chemical stability.
Complexity is acceptable only when each component serves a clear purpose and does not increase neurological friction.
All sensory attributes must serve a neurological function. None exist solely for marketing appeal.
"Completion supersedes optimisation."
Assess a ProductProducts are evaluated across five defined, measurable, and auditable domains. Products must meet minimum thresholds in every domain to qualify for verification.
Consistency of sensory output across batches and over shelf life.
Mental effort required to understand and complete the routine.
Alignment between declared and actual sensory profile.
Routine design for completion with minimal executive function demand.
Honesty alignment measured by the Honesty Gap Score (HGS).
Every verified product is classified within one of three stimulation bands — defining its dominant neurological effect on the user.
Low-frequency sensory input designed to reduce arousal and promote neurological regulation. For high-sensitivity users and regulation-focused routines.
High-frequency sensory input designed to support alertness and sensory differentiation. For under-stimulation profiles and activation-focused routines.
Minimal sensory signature designed to avoid neurological interference. Suitable for all profiles where sensory neutrality is required.
Products relying on any of the following are automatically excluded from NICD verification.
Undefined or unpredictable sensory output without neurological purpose.
Products that only work when applied in a highly specific or exacting manner.
Multi-step routines that serve brand narrative rather than user need.
Technology presented as innovative without transparent explanation.
Use of ADHD or neurodivergent language in claims without evidence or audit.
An HGS above defined limits constitutes automatic exclusion.
