Cores
A system for understanding and choosing formulations.
Cores Thirty distinct formulations, made easier to understand.
A Core contains, protects, and delivers a skincare formulation together with the information needed to understand it.
The Intrinsic Series, developed with COSMAX, begins with thirty fragrance-free formulations.
Each formulation has its own ingredients, texture, hardness, pH, water content, and formulation type.
Available in 7g, 15g, and 30g, the collection helps people compare real differences and choose according to their condition, environment, preferences, and purpose.
Physical Language A shared language for real differences.
Cosmetics are often described with emotional language that can mean different things to different people.
Physical Language adds comparable information such as ingredients, hardness, pH, water content, and formulation type.
These values are not intended to reduce a product to numbers.
They help people recognize real differences between Cores and form clearer expectations before choosing.

Graphic ID Physical characteristics translated into a visual language.
Graphic ID translates physical characteristics such as texture, flow, viscosity, and structure into a visual language.
It helps people observe and compare formulations beyond emotional imagery alone.
Personal AI Explore structured Core information with the AI you choose.
Each Core presents its ingredients and physical properties in a structured form that can be explored with the AI service a person chooses.
AI can explain terms and offer possible interpretations in context, while the final decision remains with the person.
